Which of the following provides the QUICKEST restore time?

A bare metal restore involves reinstalling the operating system and then restoring all data, which is a lengthy process compared to a snapshot.

A snapshot captures the state of a system or volume at a specific point in time and allows for near-instantaneous rollback to that state, making it the quickest restore method. Unlike full backups, snapshots typically don't involve transferring large amounts of data but rather reverting metadata or block pointers.

Restoring from an LTO-3 tape array involves locating the correct tape, loading it, and then sequentially reading data, which is significantly slower than a disk-based snapshot.

WORM (Write Once Read Many) tape arrays are designed for data archival and immutability, not for fast recovery, and restoration involves the same slow sequential access as other tape systems.
