Magnetic tape is essentially the most practical medium for creating Unix backups. Backup machines present redundancy of knowledge residing on primary storage Ought to the storage medium , reminiscent of a hard disk drive ( HDD ), fail or become corrupted, the unique knowledge is recovered from copies on the backup hardware.
Not like an inner exhausting drive , there is no need to open the computer chassis to increase storage space. The same information is then periodically written once more from disk to tape. Dropping, heating, cooling, soaking, slamming, or shouting abuse at tape cartridges could harm the media and the tape drive.
Some filesystems, comparable to XFS , present a “dump” utility that reads the disk sequentially for top efficiency whereas skipping unused sections.

A digital tape library ( VTL ) is an archival backup storage gadget that mimics the habits of physical tape. I will by no means use moveable exhausting drives as a backup for firm information. Documentation is oriented toward synchrotron use, but firewire drives could also be used for different purposes as nicely.
