As far as size, you will have no problems at 35GB.  Well, no problem if
everything else is good - I'm assuming you have an adequate system, RAM,
fast disk, etc.  What you have your "compress after X days" also plays a big
role, as browsing compressed files is considerably slower.

We use the two-stage method to put our catalog on more than one tape.  It
might fit on one tape (it's close to the LTO-1 limit) but using the
two-stage method is better for Vaulting.  When Vault runs in the morning, it
just has to run an incremental, rather than backing up the whole catalog.  

The two-stage method can scale to any number of tapes.  It is described in
the 4.5 manual.

Subject: [Veritas-bu] Size of NetBackup Catalog


Does anyone have any suggestion on the maximum size
that the NetBackup Catalog should be allowed to grow.
The NetBackup Sys Admin book only recommends that it
be able to fit on one tape. Which is at least 200 Gigs
with LTO-gen2 drives. 

With our current frequency and retention level, I'm
expecting it to be about 35 Gigs. Will this make
browsing the Catalog extremely slow?
