The data storage solutions in the market come with a shelf life, whereby when the hardware which stores your data reached a certain usage time, the chances of a malfunction increases tremendously. A Virtual Tape Library of VTL as we call it, fundamentally mimic a tape backup library but employs disks as the means. It is an archival storage mechanism that makes it feasible to hoard data as if it were being stored on tape even if it is essentially stored on disk or on a different storage medium. VTLs are disk-based arrays that are configured to look like tape libraries to host servers and to back up software. They allow data to be streamed to hard drives as if it were being stored on LTO or other formats of tape, with all backup and restore operations. The immediate benefit is in speeding up backups, which helps accommodate shrinking backup windows, and also to reduce recovery times (and especially for partial recovery where only part of the backed up information needs to be re-established). Backed up data residing on disk also remains accessible in real-time.
