I'm new to the Veritas backup product. It was installed by a third party support group. My question is generally the backup runs in 5-6 hours. Ocasionally (every 5-6 days) it runs for over fifteen hours. Comparing the job log of a short run versus a long one and the only real difference is the throughput rate. For example for the same set of files:
Average night:
2,000,000,000,000 bytes in 11 minutes and 14 seconds
Throughput rate: 173.8 MB/min
Slow night
2,000,000,000,000 bytes in 1 hour, 1 minute, 35 seconds
Throughput rate: 31.7 MB/min
I see one night is slow consistanty for a particular tape and I plan on replacing it but this is not always the case. There are no error messages other then files skipped but they are the same for both runs.
Any suggestions on how to researh this? Can dirty tapes cause this?
Thanks in advance!
