Just an FYI:

NetBackup 6.5-6.5.2 apparently decompresses the data on an NSS volume on
OES2 before it backs it up.

I don't know if other backup software has this issue.

My guess is that this is not a "Novell" issue and probably a Symantec
issue only.

But since I don't have Syncsort or Commvault or CA to test with, I don't
know if they have the same issue.

OES2 with NSS volumes with compression on and with compressed data.
