Solution
The drive is not
backing up data
efficiently.
Network, cartridge,
SCSI bus, backup
data set, or backup
application problem.
1. Check the network bandwidth from the
host server. If you are backing up data
over a network, compare to a local-only
backup for relative backup speed
indication.
2. Make sure that the drive is on its own
SCSI bus and not daisy-chained to
another tape drive or to the hard drive
being backed up.
3. Clean the tape drive.
4. Try a new cartridge. A marginal
cartridge can cause performance
problems due to bad spots on the tape
requiring retries.
5. Make sure that the data is being
compressed. See your backup
application user documentation for
details.
6. Check the size of the files in the backup
set. Small file size can impact
performance.
7. Confirm that the backup application is
using block sizes of at least 32KB, and
preferably 64KB. See your backup
application user documentation for
details.
