Hi All
Just to give you a brief background for my question.
In March this year, I changed from a Ultrium1 (MSL 5xxx) to Ultrium2 (MSL 6xxx) on my tape technology.
Every month I do a duplication of the last week's full backups to store offsite.
Before changing technology the duplication was 6-7 tapes.
When changing technology I was thinking that since I basically double the capacity per tape each duplication should be no more than 4 tapes.
I was pretty surprised to discover that duplications still ended up on 7 tapes after running completely on Ultrium 2.
The data volume increase since the Ultrium1/2 swap is very close to zerro.
My question is as follows:
Is there a way I can check if compression is actually being performed during backup?
I am running NetBackup Enterprise v6.5.1 on a Windows 2003 Server SP1.
I have verified (in device manager) that I am using Symantec tape drivers and I don't see any errors in the system at all.
Some help is greatly appreciated.
