I try to limit the amount of time I'm simultaneously reading from and
writing to any DSSU.  In my testing here with SATA Disk I take a pretty
big performance hit on the write to tape - in the neighborhood of 80%.
You could probably do better with FC or SAS Disks, but you are still
going to take a performance hit.

Subject: [Veritas-bu] Backup to DSSU, and staging to tape at the same
time?


Hello

What is the best practises regarding this? Can I do DSSU at the same
time as backup jobs use the DSSU?
I want my drives free in daytime to do restores...
