     FIELD OF THE INVENTION 
     The present invention relates to devices and methods regarding digital security, off-line backup technology and data backup technology. 
     BACKGROUND OF THE INVENTION 
     Hackers use ruthless techniques to first gain access to information technology (IT) systems, copy the data therein, destroy backups, and even encrypt all of the data such systems store. Hackers use ransomware designed to force victims to pay for decryption codes. In some instances, hackers, viruses and/or malware can be used to delete some, or all, of the data stored on computer system. Such crimes are being committed with increased frequency and sophistication. The consequences of such crimes can be devastating for businesses, victims and those affected by consequences of such crimes. 
     In the current technological environment, data is everywhere. Images, videos, documents, contacts, databases and other files are critical to creating and/or sustaining people&#39;s livelihoods, means of earning a living, or are important in their personal lives and/or business. Such data can easily be lost, damaged, corrupted, stolen, deleted, made inaccessible, or otherwise interfered with by hackers, malicious individuals or through negligence or equipment failure. Cloud-based storage can also be affected by such destructive influences. Data that is connected to computers, systems, networks, online and/or in the cloud is vulnerable to damage, destruction, modification, or denial by lock-out. 
     Technological solutions that defend against cybercrime and destruction or loss of victim&#39;s data are desperately needed.

     USB Timer—Scheduled Backup Device Selector 
     Devices and methods for backing up digital data on storage devices which are automatically selected on an individual basis for digital connection, data exchange and data storage on a scheduled basis and each kept digitally disconnected, by manipulating either the multiplexer (data selector/digital switch) gates (ON/OFF) also referred to as combination logic circuit or by manipulating the individual USB port interface control (IC) chips using ON/OFF when not selected and connected for backup data transfer and storage. Devices and methods which backup data on one of a number of offline storage devices by connecting a selected storage device, back up data onto it and then disconnecting it, in order to isolate the backed up data and optionally allow a different storage device to be used for the next back-up event/task. 
     In an embodiment, this device allows the operator to store backups offline for security and storage purposes, and only available during certain pre-scheduled times which can be manipulated by the local device interface, not the host system (e.g. the system being backed up/protected). Hackers would not be able to delete all of the user&#39;s backups, thus achieving an automated off-line protection. In this embodiment the operator can set up multiple varying schedules including once only backup, which in an embodiment is disconnected until the operator decides to bring the storage device back online. The device is programmed in such a way that allows the local operator to manipulate the connected storage devices. In this embodiment, it is not possible to remotely change a respective USB storage port  22  status from “on” in which it can exchange data to “off” in which no data is exchanged with that respective USB storage port  22 . Likewise, in this embodiment, it is not possible to remotely change a port&#39;s status from “off” in which no data is exchanged with the port to “on” in which it can exchange data. Similarly, in this embodiment, it is not possible to remotely change and/or adjust the schedule data. Thus, this design prevents remote hackers from gaining access to storage devices which were already disconnected from the host system. 
     In addition to its ordinary and customary meaning, herein the term “open” means that there is an active digital pathway for sending and/or receiving data. 
     In addition to its ordinary and customary meaning, herein the term “closed” means that there is no longer an active digital pathway for sending and/or receiving data. 
     In addition to its ordinary and customary meaning, herein the term “turn on” means that a particular digital interface, gate or pathway is activated to allow for sending and/or receiving of data. Additionally, “on” means previously activated and/or active to allow sending and/or receiving data. 
     In addition to its ordinary and customary meaning, herein the term “turn off” means that a particular digital interface, gate or pathway is deactivated and can not send and/or receive data. Additionally, “off” means previously deactivated and/or can not send and/or receive data. 
     In addition to its ordinary and customary meaning, herein the term “connect” means to digitally activate a pathway to allow sending and/or receiving of data to and/or from a storage device or host. Additionally, “connected” means previously activated and/or active to allow sending and/or receiving data. 
     In addition to its ordinary and customary meaning, herein the term “disconnect” means to digitally deactivating a pathway which will prevent sending and/or receiving of data to and/or from the storage device or host. Additionally, “disconnected” means previously deactivated and/or can not send and/or receive data. 
     In addition to its ordinary and customary meaning, herein the term “open” means that there is an active digital pathway for sending and/or receiving data.

     In addition to its ordinary and customary meaning, herein the term “turn off” means that a particular digital interface, gate or pathway is deactivated and can not send and/or receive data. Additionally, “off” means previously deactivated and/or can not send and/or receive data. 
     In addition to its ordinary and customary meaning, herein the term “connect” means to digitally activate a pathway to allow sending and/or receiving of data to and/or from a storage device or host. Additionally, “connected” means previously activated and/or active to allow sending and/or receiving data. 
     In addition to its ordinary and customary meaning, herein the term “disconnect” means to digitally deactivating a pathway which will prevent sending and/or receiving of data to and/or from the storage device or host. Additionally, “disconnected” means previously deactivated and/or can not send and/or receive data. 
     In an embodiment, this device achieves security to the data backups because the microcontroller that controls the backup process it is isolated. In an embodiment, the microcontroller has a sole role in which it executes a task based on schedule, and that task is to issue commands to the multiplexer to disconnect/connect (close/open) a given storage device port. In an embodiment, this microcontroller runs a program and controls only the multiplexer and is isolated from the host, the data and the storage device. The microcontroller has a direct connection to the Multiplexer(s)/USB hub(s) or interface control chip(s) and does not have a direct control connection to the host. Optionally, or as desired, one or more multiplexer(s) can be used and/or one or more USB hub(s) and/or interface control chips(s). Herein, the term “hub” and USB hub” are used interchangeably. The microcontroller has a predetermined schedule which can be further adjusted to the needs of the user for the purpose of offline data storage/protection. In an embodiment, the microcontroller is isolated from and/or does not come in contact with the data (the multiplexer/USB hubs do). Thus, in such configuration, the microcontroller will not be subject to be exploited by the data being transmitted, e.g. the microcontroller will not be exposed, or subject, to data corruption, viruses, malware and other malicious data or damaging data, or data or components of the data flow from a host, or other source. For example, even if the data being passed to the storage device is malicious, the microcontroller will not be infected, altered or affected. The microcontroller does not process any data that is being transferred from the host to the selected storage device, or vice versa. The microcontroller acts as a “traffic controller” and directs which storage ports are visible to the host system(s). In embodiments, malware that can be protected against includes in non-limiting example: viruses, adware, trojan horse code, worms, ransomware, root kits, bots, and other types of malware. 
     Furthermore, in an embodiment the microcontroller is also not visible, or subject, to the host or its data flow. Therefore, if the host was compromised, an attacker or malicious event, virus, corrupt data and/or malware, cannot turn on specific ports in the device in order to access, read, delete, or affect, the backups from previous hours/days/weeks/months—held by other storage devices that are offline but still can be physically connected to the device. In other words, if the backup occurs and completes on Friday night and the hackers deploy ransomware on Sunday the Friday&#39;s backup has been offline and can not be corrupted by the malware. The operator will be able to simply connect the storage device with Friday&#39;s backup directly to the host and restore the affected data. 
     In an embodiment, the multiplexer does not interpret or store the data; rather—it provides the means and/or capability of data transfer from the host to the selected storage device. 
     In an embodiment, the multiplexer does not have a microprocessor or memory, therefore it also cannot be exploited by the data traveling through it. The multiplexer comprises of a series of interconnected gates that connect/open and disconnect/close based on directions from a separate interface (lines)—which accept commands sent from the microcontroller and allow the specific gates to connect/disconnect (open/close; turn on/turn off) so that only a particular storage interface is connected to the host. 
     In an embodiment, data backups can be accessed by a second operator at a second location different than the location of a first host system operated by a first local operator. 
     The device control can be further extended to a remote location by adding a 4G/5G or Wi-Fi/Bluetooth (Bluetooth also as “BT”) module, or other wireless protocol and/or means and/or capability, to the microcontroller, to such that the device can be controlled remotely. More over other wireless or wired communication systems, e.g. such as Ethernet, can also be utilized in the context of this embodiment to allow secure remote control of the device, as well as data transfer. The remote operator can perform all tasks related to scheduling and allowing devices to be on or off line by having the microcontroller send manual control parameters to the multiplexer. This cellular data connection would be independent and isolated from the device&#39;s host local network/internet as to not be hacked. The WiFi and Ethernet connection would allow the device to be on the local network—but this can be viewed as riskier if the hackers already penetrated the defenses of the network and can gain access to this device via network and control the active backup device. These features allow an IT professional to maintain the devices, rotate storage devices, or diagnose them as needed. Furthermore—the remote operator can select the active storage device and retrieve any backups through the host&#39;s remote connection for the local user, without the local user&#39;s interaction.

Such structures, devices protocols encompass for example computer bus interfaces, e.g. USB (universal serial bus), SATA (serial advanced technology attachment), NvMe (non-volatile memory express), as well as the cables, connectors and protocols for such bus interfaces. Additionally, A “means for exchanging data” expressly encompasses software and middleware, as well as hardware for achieving an exchange of data between the data storage device  22  and data backup device  1  and vice versa. 
     
       FIG. 1 
     
       FIG. 1  shows a diagram of an embodiment of an external device. 
       FIG. 1  shows an embodiment of a data backup device  1 , having a plastic enclosure  2 , a display screen  3  and menu control buttons  4 , e.g.  4 A,  4 B,  4 C and  4 D (menu control buttons  4 A- 4 D). In the  FIG. 1  embodiment, the data backup device  1  has a USB host port  5  which can be connected to a host system  18  via a USB cable  17 . This embodiment has a plurality of USB ports which connect to data storage devices, herein referred to as “USB storage ports”, e.g. USB storage ports  90 , e.g. USB storage ports respectively  6 ,  7 ,  8 ,  9 ,  10 ,  11 ,  12  and  13  (USB storage ports  6 - 13 ).  FIG. 1  shows an example of an optional USB extension cable  21 , e.g.  21 A,  21 B,  21 C,  21 D,  21 E,  21 F,  21 G and  2111  (data storage devices  21 A- 21 H), to a data storage device  22 , e.g.  22 A,  22 B,  22 C,  22 D,  22 E,  22 F,  22 G,  2211  (data storage devices  22 A- 22 H).  FIG. 1  also shows the data backup device  1  power port  14  having a 5V power cord  199  and adapter  200  plugged into power port  14  which can be plugged into a US 110V electrical wall socket  210  to power the data backup device  1 . 
     In an embodiment, the disclosure herein results in a foolproof backup that is not accessible to an internet or otherwise connected user. The data backup device  1  provides a foolproof backup this is both automated in regards to the schedule, e.g. day and/or day, and time, by which back-up data is received and stored and then taken offline to secure that backed up data without manual intervention. 
     In addition to its ordinary and customary meaning, “data storage device” expressly encompasses USB flash drives, thumb drives, hard drives, solid state drives (SSD), solid state flash memory, memory chips, memory cards, or other nonvolatile data storage device. 
     The data storage device  22  types which can be used with data backup device  1  can be the same or different. For example, the operator can use different storage media for different types of backups. For example—a small, e.g. less than 64 GB of, database backup which runs daily can be sent to a USB flash drive having a memory capacity compatible with the small, less than 64 GB, backup data storage requirement. In another example, where a full system backup, e.g. having greater than 500 GB of day, that runs on Saturday would necessitate that use of a larger hard drive what could record that amount of backup storage data. An operator who would like to have the fastest transfer rate may elect to use solid state drives for backups that are scheduled during the day, and hard drives for backups at night or Saturdays. 
     The data storage device  22  types which can be used with data backup device  1  can be the same or different. In another example different types of data storage devices  22  can be used. 
     Given that these data backup device consists of USB storage ports—there is a variety of USB devices that can be plugged into any of them the user can plug a USB flash drive into USB storage port  6  and plug external SSD in port  7 , and plug an external hard drive in port  8 . 
     In an embodiment, the backup is an off-line backup. An off-line backup is not available to anyone online. An off-line backup is not available to anyone from the internet. An off-line backup is not available to anyone on an intranet, or otherwise connected to the system being backed up. In other words, in embodiments, only the person with physical access to the device can control the operation of the device, and therefore controls access to the storage devices attached. 
     Criteria Selection of a Storage Device 
     End users will select the storage device based on their data size requirements. For example, a system with 10 GB of data can be backed up using a 16 GB USB flash drive, or a number of 16 GB USB flash drives setup for each day of the week and rotated weekly/monthly as desired. 
     Organizations with small amounts of data, e.g. 1 GB can for example elect to use several USB flash drives with storage of 4 GB to make sure all the data fits and allows for some additional growth in the future. 
     Organizations with more data, e.g. greater than 500 GB for example, can elect to use a number of external hard drives with storage of 1 TB, or other values of memory, to make sure all the data fits and allows for some additional growth in the future. 
     Organizations with even more data, e.g. greater than for example 10 TB can elect to store their data on external hard drives with capacity of 12 TB or 16 TB by connecting several of these drives to the storage ports of the device. 
     How a Storage Device is Connected to Receive Data 
     Once the microcontroller determines that it is time to connect a particular port to the host, it sends a signal to the multiplexer to perform the operation. The external device appears as if “plugged in” to the host system. The host system at a scheduled interval and using its own backup software or code will send the data files to the storage device. Because the host system is not aware of the data backup device, only the specific storage device that is selected by the microcontroller on the schedule basis is visible to the host. To the host, the storage device appears as if it was just manually plugged in by the user. 
     How a Storage Device is Disconnected to Protect the Stored Data 
     Once the microcontroller determines that it is time to close the USB storage port to the host, it sends a signal to the multiplexer or interface control chip to perform the operation. The external device appears as if “unplugged” from the host system, thus taking that device off-line and protecting the contents of the storage device. Since the host system is not aware of the data backup device, the host system sees the storage device as if it was just unplugged by the user. The microcontroller would send a code to the multiplexer or interface control chips to close the gate to the particular USB storage port. 
     How to Switch Between One Storage Device and Another 
     The microcontroller is programmable via LCD display screen and menu control buttons  4  on the device. The user programs the schedule using the menu control buttons  4  and display screen menus to indicate which device is to be turned on at what time. If a user determines that they need immediate access to any particular device, the user would go into the override menu and select the active port manually. Once the user&#39;s task is completed, the user can revert back to running the original schedule as previously programmed. This manual operation mode is selected from the display screen and the data backup device does not execute scheduled code until the operator changes the mode from manual to automatic. The user can also physically disconnect the storage device containing the needed backups and plug it directly into the host, bypassing the data backup device to gain access to the data. This can be useful in rapidly gaining access to the backup data in the event of a system crash/malware. Furthermore, the operator can at any point remove a storage device from the data backup device by simply unplugging it. 
     Options for Configuring Storage Devices and Switching Between them 
     The schedule is what controls which device is visible to the host. The configuration allows for date/time setting and repeated backups, e.g. for example the user can elect to have five (5) daily backups, one weekly and one monthly backup to two different devices. The user would enter the schedule menu and edit as follows: 
     Storage Device 1 ON Mondays at 6 pm OFF Mondays at 10 pm; 
     Storage Device 2 ON Tuesdays at 6 pm OFF Tuesdays at 10 pm; 
     Storage Device 3 ON Wednesday at 6 pm OFF Wednesdays at 10 pm; 
     Storage Device 4 ON Thursday at 6 pm OFF Thursday at 10 pm; 
     Storage Device 5 ON Friday at 6 pm OFF Friday at 11:30 pm; 
     Storage Device 6 ON Saturday at 4 pm OFF Saturday at 8 pm; 
     Storage Device 7 ON 1 st  Sunday of the January/March/May/July/September/November at 4 pm Off same day at 8 pm; and 
     Storage Device 8—ON 2nd Sunday of February/April/June/August/October/December at 4 pm—off same day at 10 pm. 
     In another example of a schedule a user can set one backup per week for eight (8) weeks, depending on how many storage devices are connected to the drive. 
     In another example, the schedule can be of any length desired by the use, e.g. 15 minutes, 30 minutes, 1 hour, 5 hours, or 10 hour, or 12 hour, or other time period. 
     Backups can be stored in respective USB storage devices  22  on a schedule and/or rotation of respectively scheduled and/or selected USB storage devices, in which the storage devices can be of number ranging from 1 to N USB storage devices  22 , e.g. N can be any number n from 1 to a large number, e.g. 2, or 5, or 7, or 10, or 12, or 14, or 30, or 31, or 365 or more, USB storage devices  22 . 
     The number of USB storage devices  22  selected for use by a user can be tailored to a user&#39;s desired backup strategy. For example, if a user&#39;s organization requires that all daily backups are to be stored offline for a period of 30 days, the operator can order a device that has 30+ storage ports, e.g. USB ports. This approach would achieve the capacity for executing one backup per day which is automatically kept offline on respective USB storage devices. Optionally, the USB storage devices can be reused after 30 days has passed. 
     The number of USB storage devices can also be dictated by the availability of USB storage devices, or other back up devices and/or backup drives, storage capacity of respective devices and budget of the user. In an example, some users can elect to use an embodiment of the data backup device with  7  or  8  storage ports and use some of user&#39;s existing (user&#39;s currently owned and available) USB storage devices. Other users, can elect to use an embodiment with greater than 8 ports, or 30 or more ports, or many, e.g. 365 ports. 
     Example 1—Malware Scenario 
     In nonlimiting example, when malware infects a host system it can spread through the entire network, infecting all systems on a network, significant portions of a network and/or system(s), deleting backups automatically (as seen with latest versions of ransomware malware), or encrypting everything that it finds connected to the compromised systems. Furthermore, the attacker can manually access tape backup systems if online and erase tapes or other online backup media. This can include external hard drives, flash drives, tapes, network attached storage, and servers, or other non-transitory memory devices, commonly used for storing backups. In this scenario—the malware can actually infect the host system which backs up its data through the device. Once it encounters the device, it does not know of its existence—and the only thing the malware can access is the storage device containing backups from the device that is active on the device—for example if the malware infects the network on Friday at noon—Thursday&#39;s data is already backed up and put offline as per schedule, and only Friday&#39;s backup device can be visible (if configured that way) to the host and that backup can be deleted by the malware. However, the backups from Monday, Tuesday, Wednesday and Thursday and Saturday/Sunday or a month ago were off-line during the malware attack and therefore could not have been touched by the malware. The organization can fully recover from last day&#39;s backup. Furthermore—if the backup device was configured to only be online between 6 pm and Bpm on the same day—the window which the storage device is online is only 2 hours, and after Bpm—all storage devices are again offline, and the next device does not come online until 6-8 pm window the next day (if such configuration is selected by the user). 
     Example 2—Hacker Scenario 
     In nonlimiting example, once hackers have gained access to the organization&#39;s data and systems, they usually download all the valuable data (Intellectual property, financial or personally identifiable information, or other proprietary data, or other proprietary data) to their own systems and have time to check backup locations and encrypt backups or delete them before launching a ransomware attack towards the compromised organizations systems. This is to ensure that the victim organization or user will have no choice but to pay the ransom to get their data back. Furthermore, the more valuable the data and/or the bigger the organization, the larger ransom amount is demanded. While this device cannot prevent the theft of data already on the host system (for example a file server that is physically connected to the device) it will protect the organizations/users data by keeping off line previously stored backups. If a hacker looked at the storage device connected on Friday at noon he or she would only see the storage device connected for that particular day and not for the days before. Furthermore, with more accurate scheduling which is possible with the device for example storage device can become available for only 30 minutes or 1 hour in that 24-hour period the hacker cannot even notice the device and the backups would not be affected at all. 
     Consider also that the hacker would not be able to determine that a device is responsible for taking backup devices offline. The USB storage device (such as a USB Flash drive, external hard drive, or other data storage device) would appear as if just plugged in by a user or unplugged by the user at the end of its scheduled online time. The hacker would have no way of knowing that a device is responsible, nor would it be able to know right away of its existence. In addition, the hacker cannot access the microcontroller to force any other storage devices from previous days to come online until the next scheduled task would run again a day, a week, 2 weeks or a month later as per user&#39;s specific configuration and schedule. 
     Example 3 
     In an embodiment, a device can have the following features, characteristics and methods of operation:
         Device is controlled via menu control buttons  4  and small LCD display screen that allows the user to change schedule and define which port is active and therefore controls which USB device (flash drive or hard drive) is visible to host system, which is connected via USB.   Schedule example:
           Monday USB storage port  6 , i.e. with a first USB flash drive is active from 5 μm to 9 pm;   Tuesday USB storage port  7 , i.e. with a second USB flash drive is active from 5 μm to 9 pm;   Wednesday USB storage port  8 , i.e. with a third USB flash drive is active from 5 μm to 9 pm;   Thursday USB storage port  9 , i.e. with a fourth USB flash drive is active from 5 μm to 9 pm;   Friday USB storage port  10 , i.e. with a fifth USB flash drive is active from 5 μm to 9 pm;   Saturday USB storage port  11 , i.e. with a sixth USB flash drive is active from 5 μm to 9 pm;   Sunday USB storage port  12  is active i.e. with a seventh USB flash drive is active from 5 μm to 9 pm, which can optionally be a monthly backup;   USB storage port  13  can be used, e.g. for executing a custom defined backup using a thirteenth USB flash drive (in other embodiments N+1 n ports could be used with N+1 . . . n respective USB flash drives, or other data storage device  22  for backup when scheduled to be active);   
           While one port is active, all other ports are off-line;   Status display screen (Default)—indicates which device is active;   Using third party backup software—such as Windows Backup or Acronis backup, we can schedule the full backup to be stored on the flash or hard drive. Therefore, each USB flash drive contains a full back-up from a different time/day. Thus, giving the operator an off-line backup that cannot be erased or subjected/exposed to ransomware.       

     Example 4 
     In another embodiment, a device can have the following features, characteristics and methods of operation:
         Approximate dimensions are 10×6×4 inches;   USB can use latest standard, such as USB C (or a previous version i.e. 3.1 generation 2);   N+1 USB Ports are used as storage devices (there is no limit as to number of devices—additional multiplexers and/or hubs just have to be chained together to add more ports);   Storage capacity is limited only to the individual device. (USB flash drives can be used and they are commonly found with 1 TB of space or external hard drives as big as 12 TB can be connected);   1 USB Port is used as host interface;   External AC adapter USB will provide power to the device;   system on chip open source Arduino is used as program controller;   Onboard battery and system clock will make sure the device schedule remains if power is disconnected;   Host can be Desktop/laptop/server—MAC/PC/LINUX or other operating systems;   Data backup device microcontroller is not visible to the host system, only the active USB storage device is.
 
As used herein, in addition to its ordinary and customary meaning, “host” expressly encompasses any device holding digital information and/or data. Additionally, “host” expressly encompasses any device holding digital information and/or data that can exchange data with data backup device  1  as disclosed herein, e.g. though USB (universal serial bus), NvMe (NvMe, e.g. using a PCI bus) and SATA (serial advanced technology attachment) as well as the cables, connectors and protocols for such bus interfaces, or other technology which can exchange data with data backup device  1 .

     Example 6 
     In another embodiment, a device can have the following features, characteristics and methods of operation. 
     The operator can connect an external USB hub to any of the storage ports and thus allow multiple storage devices (USB flash drives or external hard drives) to be visible to the host all at the same time. Allowing multiple backups to occur to those different devices at the same time when the storage device port is selected for backup. Those devices will become visible to the host and allow the host read/write to the devices connected through an externally connected USB hub. When the storage port is disconnected, all of the devices on the external USB hub will become offline and no longer visible to the host. 
     Example 7 
     In another embodiment, a device can have the following features, characteristics and methods of operation. 
     The host backup software can be scheduled to run a backup nightly at 9 pm. The device can be configured to turn on the first storage device at 8:55 pm. The storage device will be recognized by the host system and assigned a drive letter (or mount point) prior to scheduled backup taking time. The backup software will store the backup file to a predetermined drive letter (or mount point) and the backup takes 1 hour to complete. The data will flow through the hosts USB port to the device&#39;s USB host port, through the multiplexer and/or USB hub to its designated storage device port with the associated storage device connected to it, and be stored on the storage device. The device can be configured to disconnect USB storage port  6  at 10:05 pm and therefore the completed backup is now placed offline. The device will remain idle until the next scheduled event, which can be 8:55 pm the next day, and select the second USB storage port  7  to be active. Furthermore, the backup software on the host can be configured to automatically detect any of the storage backup devices upon its activation by the device controller and begin backup as soon as it is detected. The backup operator must allow sufficient time in the programming of the device for the host backup to fully complete before scheduling the storage port to go offline. 
     Example 8 
     In another embodiment, a device can have the following features, characteristics and methods of operation. 
     To setup the device, the operator will first plug in each of the storage devices directly to the host (bypassing the data backup device) and format each storage device for use with the host system. Each storage device should have a unique drive label (e.g. 
     Monday/Tuesday/Saturday etc., for example) which will help the host&#39;s backup software identify the backup device and apply the proper backup plan. Once formatted, the operator will plug in the storage devices to their respective USB storage ports in the data back device  1 . Next, the operator will plug the device&#39;s USB host port into the USB port of the system to be backed up using a USB cable. Using the device&#39;s control panel, which will now be activated and displaying a menu, the operator will set its date and time, and select a default or custom schedule (adjusted to the operators needs and backup window timeframe) and set the device to run in automatic mode. Based on the date and time, the device will execute the scheduled tasks allowing a particular storage port to be turned ON, and making the storage device plugged into it visible to the host. Allowing for the host to transfer the backup file to the selected storage device, and turning the storage port off after the predetermined schedule task is finished.

       FIG. 3  shows a diagram of an embodiment of controller logic. The controller works on a programmable schedule which depends on the clock and data of the microcontroller. The microcontroller will execute each task at a predefined interval. 
     For example, the microcontroller will tell the multiplexer to connect USB storage port  6  to the host via USB host port  5  for a predefined amount of time, and then disconnect USB storage port  6  from the multiplexer  19  by deselection of USB storage port  6  by the microcontroller. 
     Logic and Programming
         Using the logic and programming consistent with timing and scheduling, the device will at predefined intervals connect the external host port, to a particular USB Storage port  6  through  13 .

The microcontroller  16  would on schedule allow the respective host (host port  5  and  41 ) to interface with any respective predetermined storage device connected through the storage ports ( 6  through  12 ) on the USB hub during their scheduled times. 
     In addition to its ordinary and customary meaning, “nested USB hubs” means USB hubs which are interconnected and configured in a hierarchical structure. For example, “nested USB hubs” expressly encompasses a host which is connected to the main/top/root hub must connect through a data backup device  1 &#39;s secondary hub to connect to the storage device attached to a subsequent nested hub. 
     The use of USB Hubs allows the device to be configured in such a way so that all storage ports are visible to one of the hosts at the same time allowing for maintenance/troubleshooting or initial setup of all storage devices prior to running program/schedule which would control access to storage devices on user determined schedule. Using interface control the device can make visible any of the storage devices connected by enabling/disabling that particular USB storage port  90 , e.g. USB storage ports  6  through  12 , including the port  5 , e.g. HOST1, and port  41 , e.g. HOST2. For example, the schedule logic would turn on port  5 , HOST1, to have access to USB storage port  6  by keeping all other USB storage ports  7  through  12  turned off, while manipulating interface control  43  attached to  6  to enable port  6 . Once the schedule window is over, the microcontroller instructs interface control  43  to turn off/disconnect port  6 —therefore taking USB storage device  6  offline, as well as taking offline host port  5 , e.g. HOST1, by manipulating the host port  5  interface control  43  attached to host port  5 , e.g. HOST1. 
     
       FIG. 4B 
     
       FIG. 4B  shows a diagram of an embodiment of controller logic for an embodiment having USB hubs 
     In the USB hub embodiment, as shown in  FIG. 4A , the microcontroller  16  runs tasks based on a preprogrammed date/time schedule, as shown in  FIG. 4B . The scheduled task runs, as shown in  FIG. 4B , comprise, for example, a series of tasks, e.g., Task  1 , Task  2 , Task  3 , Task  4  and Task N. The scheduled task runs are not limited to the number of Scheduled Task Runs, as shown in  FIG. 4B , but can include more or less Task Runs depending on the desires and needs of the end user. Each Task, i.e., Task1-N, includes a day/time and the USB/IC part to turn on, or make visible to the USB hub. When the preconfigured interval/time starts for task  1 , the microcontroller  16  sends a command, for example, to the specified USB storage port to turn on. That particular storage port ( 6 - 12 ), as shown in  FIG. 4A , enables the storage device attached to it to be visible to the host by connecting it to the USB hub  42 , as shown in  FIG. 4A . The host is always connected to the USB hub by its host interface control  43 , as shown in  FIG. 4A , in this embodiment, but only when the task is executed is the host is able to send backups to the storage device. Upon completion of the time/schedule—the microcontroller  16  sends a command to a respective USB storage port to disconnect. Which in turn makes the storage device no longer visible/connected to the host via the USB hub  42 . The next scheduled interval uses the same logic. 
     
       FIG. 5 
     
       FIG. 5  shows a diagram of an embodiment of an internal device using directly connected interface control chips. 
     The embodiment of  FIG. 5 —has display screen  3  connected to the microcontroller  16  and control buttons/knob  31  also connected to the microcontroller. The microcontroller  16  can optionally be outfitted with ethernet  28  and Wifi/Bluetooth (BT)  30 . Each USB port  5 ,  6 ,  7 ,  41  has a dedicated interface control chip attached to it  43  which allows the microcontroller to manipulate each individual USB port  5 ,  6 ,  7 ,  41 . 
       FIG. 5  shows a device comprised of direct connected Hosts ( 5  and  41 ) to their own respective storage ports ( 6  and  7 ). The microcontroller  16  on schedule would make USB storage port  6  into which a first storage device is connected only visible to the host, e.g. HOST1, via host port  5  by controlling the interface controller chip  43 . Similarly—the microcontroller can also make a second USB storage device connected to USB storage port  7  visible to a second host, e.g. HOST2, via a second host port  41  on schedule by turning on the respective interface controller chip  43  on both ports. The device in this embodiment, enabled the user with several systems to interconnect multiple storage devices through a single USB backup device and activate individual backup devices on schedule. 
     In this embodiment, multiple hosts can be backed up and protect by a single data storage device  1 . The schedule of backing up multiple devices with a single data storage device  1  can be defined such that each respective host can be backed up to any USB storage device  22  in accordance with scheduling criteria. 
     The device can also connected to only one host during a given time period for backing up to a specific USB storage device  22 , allowing the user to turn on and off the single storage device during specified backup time, to guard against data loss by malware/hackers/human error etc. as discussed in the introduction. The number of hosts and respective storage ports is not limited. The microcontroller can turn on/off multiple one to one connections on schedule by the use of interface controllers.
