Time Required for
Backup
1
Not only is the amount of data that needs to be backed up growing, but
the time window for performing the backup is shrinking due to the
impact of global operational expansion. Adding more tape drives is no
longer an efficient way to reduce the time required for backup.
Confidence in
Completing the Backup
1
Confidence in completing the backup job within the backup window can
be very low because of time constraints or “hang ups” during the backup
process due to errors generated by mechanical problems. If these types of
errors could be eliminated by removing issues that are inherent in any
mechanical device, confidence in the backup job completing would
improve greatly.
Time to Restore Data
1
The time required to restore data from a tape library is determined by
how long it takes to mount a cartridge in a tape drive and find the proper
position on the tape. This can take several minutes and then the restore
time is also reduced by the tape drive transfer speed. Restoring data from
hard drives (emulating tape cartridges) improves restore time by
eliminating the time required to load a cartridge and transfer speed
restrictions.
