If you can successfully reconstruct these files, it could take weeks, or even months, to accomplish. Realizing the importance of your computerized data is the first step. Next, users need to ask their resellers the right questions to ensure that they get the protection they want and need. Low-capacity tape drives are less expensive than SCSI systems and usually connect to a computer via the floppy controller or parallel port. These drives typically store from 250 to 700MB and provide an affordable solution for protecting individual systems.
Most drives are available in either internal or external configurations.
This means they are either installed in one of the drive bays or are completely self-contained in their own enclosure. The tape drive you purchase will depend on how much data you are protecting and the performance you need. Internal vs. external is a matter of personal preference. External units are typically more expensive because they have a separate enclosure and their own power supply. Internal units take up less desk space but you need to have a spare drive bay to install it.
