Backup Exec 2010 & Qauntum Superloader 3: Lack of Compression on Full Backups (ratio 1:1)
I had issues with a pre-existing BExec installation and tape drive so I basically ripped it all out and re-installed from scratch. It is now working wonderfully, except for one major issue - I cannot get any compression when backing up to tapes, whereas an identical install and config at another of our sites gets 2:1 compression regularly.
Backup Exec 2010 R3 Sp1 with all Hotfixes
Using Symantec drivers within Bexec.
Quantum Superloader 3 has latest firmware and runs without issue.
The servers being backed up range from File & Print, to Exchange, to App Servers (all virual running on VMWare 5).
I have tried pretty much every suggestion I can find on the net but am still at a loss, and it's quite critical to resolve this as my tapes are getting eaten up.
The only difference I see on the 2 sites is backup speeds; at the site that gives compression the backups often regist over 4Gb/min whereas at the problematic site I can only achieve 1.5Gb/min - it's ample, but curious why such a difference?
Someone please help!!!
Many thanks in advance
