I'm trying to do a backup, and it seems to be taking more tapes than I
expect it should.
Here are the details:
NetBackup Data Center 3.4.1
Solaris 8 master and media servers and clients
DLT tapes, 35GB capacity
I'm backing up this client:

I've got the class set up as follows:
"Active" and "Follow NFS" are checked, all other choices (compression,
cross mount points, etc) are unchecked.
The file list to back up is:
/
/opt/apache
/opt/apache/logs
/auspex/content
/auspex/vol00
/auspex/vol01
/auspex/vol02
/auspex/vol03
/auspex/vol04
By my calculations, those filesystems total 1,279,211,090k, which is
1,249,229MB=1,219GB.
1,219 GB / 30 GB per tape = 40.63 tapes. (bpmedialist is reporting I'm
getting roughly 31GB per tape for those big "volxx" volumes -- it's already
compressed audio data).
However, I've used over 80 tapes already, and the backup isn't finished
yet. I don't understand why it's taking so many tapes. These are fresh
tapes.
Any ideas?
Thanks very much,
-Adam
