Which one of the following entails immediately transmitting copies of on-line transactions to a
remote computer facility for backup?
A.
Archival storage management (ASM)
B.
Electronic vaulting
C.
Hierarchical storage management (HSM)
D.
Data compression
Explanation:
“Electronic vaulting makes an immediate copy of a changed file or transaction and
sends it to a remote location where the original backup is stored….Another technology used for
automated backups is hierarrchial storage management (HSM). In this situation, the HSM system
dynamically manages the storage and covery of files, which are copied to storage media devices
that vary in speed and cost. The faster media hold the data that is accessed more often and the
seldom-useed files are stored on the slower devices, or near-line devices. The different storage
media rang from optical disk, magnetic disks, and tapes. Pg. 619 Shon Harris CISSP All-In-One
