Question
What technology may be used to perform disk-to-disk backups with systems designed to work only with tapes?
Options
- AJournaling
- BD2D
- CVLAN
- DVTL
Explanation
VTL (Virtual Tape Library) emulates physical tape drives and libraries using disk storage, allowing backup software designed exclusively for tape to write to disks without modification - giving you the speed and reliability of disk with full compatibility for tape-only systems.
- A (Journaling) is a filesystem technique for crash recovery, tracking changes before writing them - unrelated to backup media compatibility.
- B (D2D) stands for Disk-to-Disk and describes the concept of the backup type, but is not a technology that makes tape-only systems work with disks.
- C (VLAN) is a network segmentation technology - it has no role in storage or backup media translation.
Memory tip: Think "VTL = Virtual Tape Library" - it's a virtual layer that lies to tape-backup software, making disks look like tapes.
