## Background
BACKGROUND
Organizations increasingly rely on virtualization technologies to improve the flexibility, efficiency, and stability of their data centers. These organizations may fulfill a variety of computing requirements using virtual machines provisioned with appropriate virtual hardware, operating systems, applications, and configurations.
Unfortunately, managing a large number of virtual machines may require a significant amount of work on the part of an administrator. Creating and configuring new virtual machines, locating and restoring old virtual machines from backup, compiling information on existing virtual machines, and various other tasks may constitute repetitive and tedious work for administrators who could better spend their time on other tasks. Accordingly, the instant disclosure identifies a need for systems and methods for enhancing virtual machine backup image data.
SUMMARY
As will be described in greater detail below, the instant disclosure generally relates to systems and methods for enhancing virtual machine backup image data. Systems and methods described herein may gather information on the configuration of virtual machines during backup (e.g., virtual hardware, installed applications, operational context, etc.) and associate each backed up virtual machine with its configuration information in a searchable catalog. For example, a method may include identifying a virtual machine to be stored as a backup image, collecting configuration information that identifies at least one aspect of how the virtual machine is configured, storing the backup image of the virtual machine in a backup repository, and associating the configuration information with the backup image in a catalog of virtual machine backup images, the catalog being searchable by the configuration information.
The configuration information may include a variety of information. For example, the configuration information may include information identifying virtual hardware of the virtual machine, such a storage device type, a storage device size, a number of storage devices, a type of processor, a number of processors, an amount of random-access memory, a characteristic of a SCSI controller, and/or a characteristic of a network interface controller. Additionally or alternatively, the configuration information may include information identifying an original location of the virtual machine, such as a hypervisor monitoring the virtual machine, a server hosting the virtual machine, a resource pool including the virtual machine, a data center including the virtual machine, and/or a virtual center managing the virtual machine. In additional examples, the configuration information may include information identifying applications installed on the virtual machine and/or information identifying system software installed on the virtual machine.
Systems and methods described herein may also search the catalog described above for a virtual machine using configuration information of the virtual machine as search parameters. For example, a method may include identifying a searchable catalog of virtual machine backup images. The method may also include receiving a search query directed to finding at least one virtual machine in the searchable catalog of virtual machine backup images, the search query identifying configuration information comprising at least one configuration aspect of a sought virtual machine. The method may additionally include querying the searchable catalog with the search query and receiving an identification of a backup image of the virtual machine from the searchable catalog in response to the query.
The configuration information may include a variety of information, including the types of configuration information discussed earlier. For example, the configuration information may include information identifying virtual hardware of the virtual machine, information identifying an original location of the virtual machine, information identifying applications installed on the virtual machine and/or information identifying system software installed on the virtual machine.
The systems described herein may receive the search query in a variety of contexts. For example, these systems may receive a request to instantiate a new virtual machine with a configuration matching the configuration information. In this example, these systems may further instantiate a new virtual machine based on the backup image of the virtual machine. In another example, these systems may receive the search query in the context of receiving a request to generate a report on virtual machines within the searchable catalog that match the configuration information. In this example, these systems may further generate the report.
Features from any of the above-mentioned embodiments may be used in combination with one another in accordance with the general principles described herein. These and other embodiments, features, and advantages will be more fully understood upon reading the following detailed description in conjunction with the accompanying drawings and claims.

Backup module 104 may also collect configuration information 212 that identifies at least one aspect of how virtual machine 210 is configured. Backup module 104 may additionally store virtual machine backup image 214 in backup repository 208. Backup module 104 may also associate configuration information 212 with virtual machine backup image 214 in a catalog 210, catalog 210 being searchable by configuration information 212. While backup module 104 and search module 106 are depicted on backup cataloging system 202, all or portions of modules 102 may be located on host system 206 and/or backup system 208.
Search module 106 may be programmed to receive a search query 218 directed to catalog 216, search query 218 including at least a portion of configuration information 212. Search module 106 may also be programmed to query catalog 216 with search query 218. Search module 106 may additionally be programmed to receive an identification of virtual machine backup image 214 from catalog 216 in response to search query 218. While catalog 216 is depicted in backup repository 208, all or portions of catalog 216 may be located on backup cataloging system 202, host system 206, and/or a separate computing device.

FIG. 3 is a flow diagram of an exemplary computer-implemented method 300 for enhancing virtual machine backup image data. The steps shown in FIG. 3 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 3 may be performed by one or more of the components of system 100 in FIG. 1 and/or system 200 in FIG. 2.
As illustrated in FIG. 3, at step 302 one or more of the systems described herein may identify a virtual machine to be stored as a backup image. For example, at step 302 backup module 104 may, as part of backup cataloging system 202, identify virtual machine 210.
As used herein, the phrase “virtual machine” generally refers to a computing system platform that may not have direct correspondence to hardware of an underlying host system. For example, hardware of a host system may be abstracted to a virtual machine using a hypervisor or other virtualization software. A virtual machine may run a guest operating system and/or various other software applications. As used herein, the term “image” as applied to a virtual machine may refer a file and/or other data structure that includes data representing the contents and/or structure of the virtual machine, e.g., so as to be able to run the virtual machine and/or reconstruct the virtual machine.
Backup module 104 may identify the virtual machine in any suitable manner. For example, backup module 104 may receive a message from a host system of the virtual machine identifying the virtual machine. Additionally or alternatively, backup module 104 may identify the virtual machine while scanning a host system for virtual machines.
At step 304 one or more of the systems described herein may collect configuration information that identifies at least one aspect of how the virtual machine is configured. For example, at step 304 backup module 104 may, as part of backup cataloging system 202, collect configuration information 212 that identifies at least one aspect of how virtual machine 210 is configured.
The configuration information may include a variety of types of information. In some examples, the configuration information may include information identifying virtual hardware of the virtual machine. For example, the configuration information may include information identifying one or more storage devices of the virtual machine. In this example, the configuration information may identify various aspects of a storage device, such as the type of storage device (e.g., by interface standard, such as IDE/ATA/SATA and/or SCSI; or by storage medium, such as a hard disk drive, an optical disc drive, a solid-state drive a floppy drive, a tape-based storage device, etc.), the size of the storage device (e.g., the total storage capacity of the storage device), the amount of available storage on the storage device (e.g., accounting for software and data already present on the storage device), the number of storage devices, and/or performance specifications of the storage device (e.g., latency, throughput, etc.).
In another example, the configuration information may identify aspects of other virtual hardware such the type of motherboard, the BIOS, the number of processors, the type of processors and/or chipset used (e.g., the specific processor used, the instruction set architecture of the processor, whether the processor is single-core or multi-core, etc.), the amount of random-access memory, the type of random-access memory, characteristics of a SCSI controller (e.g., how many devices the SCSI controller can handle), the number of SCSI controllers, characteristics of a network interface controller (e.g., an identification of an emulated network interface controller and/or a virtual network interface controller, performance specifications of the network interface controller, functionality of the network interface controller, etc.). Additional examples of virtual hardware that the configuration information may identify and/or describe include a graphics card, device ports (e.g., serial ports, parallel ports, USB ports, ethernet ports, etc.), and peripheral input/output devices (e.g., keyboards, mice, printers, etc.). Generally, the configuration information may identify any aspects of any virtual hardware of a virtual machine.
In some examples, the configuration information may include information identifying an original location of the virtual machine. For example, the configuration information may include information identifying a hypervisor monitoring the virtual machine (e.g., at the time of backup). The hypervisor may be identified with any suitable information, such as a unique identification number, a name, a host device, etc. In another example, the configuration information may include identifying a server hosting the virtual machine. The server may be identified with any suitable information, such as a network address, a unique identification number, a name, etc. In an additional example, the configuration information may include information identifying a resource pool including the virtual machine (e.g., a defined group of virtual machines that share underlying physical computing resources). Additionally or alternatively, the configuration information may include information identifying a virtual center managing the virtual machine (e.g., a system managing virtual machines across hypervisors). In some examples, the configuration information may include information identifying a data center managing the virtual machine. The data center may be identified with any suitable information, such as an IP address, a unique identification number, a name, a geographical address, etc. Generally, the configuration information may include any information for categorizing and/or grouping virtual machines by location and/or systems that manage the virtual machines.
In some examples, the configuration information may include information identifying system software installed on the virtual machine. For example, the configuration information may include information identifying an operating system of the virtual machine and/or drivers installed on the virtual machine. Such identifications may also include versioning numbers. Additionally or alternatively, the configuration information may include configuration details of system software installed on the virtual machine (e.g., registry settings, system configuration file settings, etc.). In some examples, the configuration information may include information identifying system utilities installed on the virtual machine, such as security software, system profiling software, system maintenance software, etc.
The configuration information may also include information identifying applications installed on the virtual machine. Such identifications may also include versioning numbers. In addition, the configuration information may include information relating to the configuration of applications installed on the virtual machine, including installed plug-ins, configuration settings, etc.
Backup module 104 may perform step 304 in any suitable manner. In some examples, backup module 104 may harvest at least a portion of the configuration information from a profile of the virtual machine maintained by a host system of the virtual machine (e.g., a hypervisor). For example, if the virtual machine is managed by VMWARE ESX and backed up by SYMANTEC NETBACKUP, backup module 104 may harvest at least a portion of the configuration information from the file at CAProgram Files\VERITASWetBackup\online_utilVi_cntlVVirtualCenter/ESX′.xml. In an additional example, backup module 104 may query a host system of the virtual machine and/or receive a message from the host system including at least a portion of the configuration information. In another example, backup module 104 may analyze and/or parse an image of the virtual machine. In some examples, backup module 104 may collect the configuration information when backing up the virtual machine. Additionally or alternatively, backup module 104 may identify a backed up virtual machine and collect the configuration information.
At step 306 one or more of the systems described herein may store the backup image of the virtual machine in a backup repository. For example, at step 306 backup module 104 may, as part of backup cataloging system 202, store virtual machine backup image 214 in backup repository 208.
Backup module 104 may perform step 306 in any suitable manner. For example, backup module 104 may copy an image of the virtual machine from a host system of the virtual machine to the backup repository. Additionally or alternatively, backup module 104 may direct a data mover and/or a backup appliance to copy and/or replicate an image of the virtual machine to the backup repository.
At step 308 one or more of the systems described herein may associate the configuration information with the backup image in a catalog of virtual machine backup images, the catalog being searchable by the configuration information. For example, at step 308 backup module 104 may, as part of backup cataloging system 202, associate configuration information 212 with virtual machine backup image 214 in catalog 216.
The catalog may include any of a variety of formats and/or data structures. In some examples, the catalog may include a database, such as a relational database. In these examples, backup module 104 may use aspects of the configuration information as attributes in the database to relate to the backup image. Accordingly, a database query based on these attributes may yield the backup image as a result. Additionally or alternatively, portions of the catalog may be stored as metadata files maintained for each virtual machine backup image in the backup repository. In various examples, the catalog may be searchable by a single configuration aspect (e.g., as identified by the configuration information), by an exact configuration match, and/or by compound boolean expressions. In some examples, the catalog may be searchable in that it may be sortable, i.e., closest matches may appear at the top of a sorted list of virtual machines identified in the catalog. After step 308, method 300 may terminate.
FIG. 4 is a flow diagram of an exemplary computer-implemented method 400 for enhancing virtual machine backup image data. The steps shown in FIG. 4 may be performed by any suitable computer-executable code and/or computing system. In some embodiments, the steps shown in FIG. 4 may be performed by one or more of the components of system 100 in FIG. 1 and/or system 200 in FIG. 2.
As illustrated in FIG. 4, at step 402 one or more of the systems described herein may identify a searchable catalog of virtual machine backup images. For example, at step 402 search module 106 may, as part of backup cataloging system 202, identify catalog 216.
Search module 106 may perform step 402 in any suitable manner. For example, search module 106 may identify a backup repository of virtual machine backup images and locate the catalog within the backup repository. Additionally or alternatively, search module 106 may read a configuration file and/or receive a message that identifies the searchable catalog. The searchable catalog may generally include any characteristics attributed to the catalog described above in relation to step 308.
At step 404 one or more of the systems described herein may receive a search query directed to finding at least one virtual machine in the searchable catalog of virtual machine backup images. The search query may identify configuration information that includes at least one configuration aspect of a sought virtual machine. For example, at step 404 search module 106 may, as part of backup cataloging system 202, identify search query 218.
The configuration information used within the search query may include a variety of information, including any of the types of configuration information described earlier in relation to step 304. For example, the configuration information may include information identifying virtual hardware of the virtual machine, information identifying an original location of the virtual machine, information identifying applications installed on the virtual machine and/or information identifying system software installed on the virtual machine.
Search module 106 may perform step 404 in a variety of contexts. For example, search module 106 may receive the search query as part of a request to instantiate a new virtual machine with a configuration matching the configuration information. As will be described in greater detail below, in this example search module 106 may subsequently instantiate a new virtual machine based on the backup image of the virtual machine. In another example, search module 106 may receive the search query as part of a request to generate a report on virtual machines within the searchable catalog that match the configuration information. As will be described in greater detail below, in this example search module 106 may subsequently generate the report.
At step 406 one or more of the systems described herein may query the searchable catalog with the search query. For example, at step 406 search module 106 may, as part of backup cataloging system 202, query catalog 216 with search query 218.
Search module 106 perform step 406 in any suitable manner. For example, the searchable catalog may include a database and search module 106 may structure the search query as a database query. Additionally or alternatively, the searchable catalog may include an index and/or a metadata file and search module 106 may search the file for portions of the configuration information. In some examples, the searchable catalog may be searchable in that the catalog may be sortable. In these examples, search module 106 may sort virtual machine backup images referenced by the catalog according to a degree to which they match the configuration information. In various examples, search module 106 may query the searchable catalog with a single configuration aspect (e.g., as identified by the configuration information), by an exact configuration match, and/or by compound boolean expressions.
At step 408 one or more of the systems described herein may receive an identification of a backup image of the virtual machine from the search catalog in response to the query. For example, at step 408 search module 106 may, as part of backup cataloging system 202, receive an identification of virtual machine backup image 214 from catalog 216 in response to search query 218.
Search module 106 may receive the identification of the backup image of the virtual machine in a variety of ways. For example, search module 106 may receive a location of the backup image of the virtual machine within a backup repository. In some examples, search module 106 may receive a list of backup images (including the backup image) that match the query. In some additional examples, the list may be sorted by the strength of the match between each backup image and the query. After step 408, method 400 may terminate.
In some examples, the systems described herein may also instantiate a new virtual machine based on the backup image of a virtual machine identified in a search. For example, search module 106 may display the backup image of the virtual machine to an administrator based on the query. The administrator may then select an option to instantiate the displayed virtual machine. These systems may then retrieve the backup image of the virtual machine and use the backup image to create a virtual machine in a target system as selected by the administrator.
By finding, displaying, and allowing a quick instantiation of a virtual machine of a desired configuration, the systems and methods described herein may expedite some virtualization management tasks of an administrator. For example, an administrator may remove a virtual machine that is no longer of use. The administrator may subsequently require a virtual machine with the same configuration, but the administrator may not remember all of the configuration details of the original virtual machine. Using the systems described herein, the administrator may submit a search query with some of the configuration details, find a backup image of the original virtual machine, and then automatically instantiate a virtual machine with the same configuration based on the backup image. For example, the administrator could quickly find and restore a MICROSOFT WINDOWS XP SP2 x86 virtual machine with a MICROSOFT EXCHANGE installation.
In another example, an administrator could remove any currently unused virtual machines from a hypervisor and quickly find and restore them from a backup repository as needed. In some examples, a customer of a virtualization product may request a virtual machine with a certain configuration. In these examples, the backup repository may function as a golden image database for the customer.
The systems described herein may also generate a report on virtual machines within the searchable catalog that match the configuration information. For example, the systems described herein may receive a query for virtual machines managed by a specific virtual center and generate a list of such virtual machines, a count of such virtual machines, and/or statistics of hardware and/or software configurations of such virtual machines. In another example, the systems described herein may receive a query and generate a report for all MICROSOFT WINDOWS 2008 virtual machines with more than 2 gigabytes of RAM. As an additional example, the systems described herein may receive a query and generate a report for all ORACLE SOLARIS multi-computer virtual machines with similar hardware configurations. In this example, the systems described herein may also provide an option to remove duplicate backup images listed in the report.
