Compression is currently set for 7 days; we could drop it lower but that seems 
like it should be reasonable.

Solaris 8 NBU 4.5 FP5
Use 'compress catalog after' option in the Windows Admin Console, Host 
Properties->Master Server Properties->Global NBU Attributes.  I set it to 120 
days when my disk filled up and it went down to 75% full.  It also took less 
time to backup.  I'm going to try 60 days now.  I don't get requeststo restore 
anything past a couple weeks old anyway?

Subject: [Veritas-bu] Increasing catalog backup throughput rates ?


Environment:
        HP-UX 11.0 master server
        NetBackup 4.5 FP4
        HP Tachyon PCI FC HBA
        Fibre IBM LTO1 drive in an STK L5500

Our catalog backups have always run a little long, but lately it seems to have 
gotten even worse. Backing up our 83 GB catalog is taking around 6.5 hours now, 
which comes out to about 3719k/sec. Does anyone have any suggestions for 
increasing the throughput rate of this backup ? The catalog is cleaned up 
fairly often so there's not much I can do to shrink its size without altering 
our retention periods. Only the master server is being accessed for this, and 
the filesystem is off of an EMC. The backup is triggered via CLI so we do have 
backups running during it (we just don't have a 6 hour window of downtime 
daily). 

Any suggestions for improving the throughput rates would be appreciated. 
Thanks.
