Quantum DX3000 and DX5000 User’s Guide 2

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

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.
