Jamie, you should really be using the hot catalogue backup. I'd try it if I was you and see how you go.

So are you using a T2000 now or the V880 ??? I'm guessing you are using the T2000. If so, make sure you remove the kernel tuning parameters and if you have removed them, do a reboot. Solaris 10 uses much more resources than you will probably ever specify in the kernel file.

Also check your buffer settings, are they still there ??? You may be able to increase them now. What sort of drives are you using ???

Regards,

Dominik

Ever since I upgraded to NetBackup 6.0MP4 I've noticed that my offline
catalog backups are incredibly and painfully slow. When I was running
5.1MP5 it took between 1 and 2 hours to back up my approximately 150Gb
catalog. After the upgrade the offline catalog backups take well over
four hours to complete, this despite having a faster server (Sun T2000
v. Sun V880) and faster HBAs. What gives? Is this a bug or a feature?
 
 
Thanks,
 
Jamie Jamison
