Dennis,

What do you have as your backup selection inside your catalog policy.

We have always used the default backup selection in our catalog policies (1 
Daily full, daytime cumulative every hour, night time cumulative every 3 hours) 
and a quick look at our policy shows we have specified CATALOG_DRIVEN_BACKUP as 
the backup selection.  I can’t find anything that confirms exactly what is 
backed up by this backup selection but we also do our DR testing at Sungard in 
Philly and have successfully restored our catalog multiple times.

I also went into the backup and restore GUI and took a look at some of our 
catalog backups and they all seem to get the list of files you were talking 
about under /usr/openv (db, netbackup, var, volmgr).

Under /volmgr/database I see the following

.devices_ready
globDB
ltidevs
poolDB
robotic_def
ruleDB
volDB

I don't know if it makes any difference but we don't backup up anything to tape 
(all backups go to Data Domain restorers).  The one time we did try a DR 
exercise from tape we couldn't get the catalog restore to work.  That helped 
put together a pretty convincing business case to move to disk based backups 
and we've been 100% successful every time since then !!

I just checked by catalog tape ( I always do fulls)
And I do find /usr/openv/netbackup/db on the tape listing class and
images and other items.

So I checked the catalog config and see in the file list that I specify
the catalog to backup that dir.


My list
Master:/usr/openv/netbackup/db
Master:/usr/openv/volmgr/database
Master:/usr/openv/var
Media:/usr/openv/netbackup/db
Media:/usr/openv/volmgr/database
Media:/usr/openv/var
Master:NETBACKUP_RELEATIONL_DATABASE_FILES

What is in your list?

We are running Solaris 10 boxes, Netbackup 6.5.3.1

1 master server
4 media servers
SL8500 tape library with T10Kb drives

Just got back from a Disaster Recovery Exercise at Sungard in Philly.
What we discovered is: 

Full Catalog backup does NOT backup /usr/openv/db but DOES backup
/usr/openv/netbackup, /usr/openv/var, & /usr/openv/volmgr.
Differential/Incremental Catalog backup DOES backup the following:
/usr/openv/db
/usr/openv/netbackup
/usr/openv/var
/usr/openv/volmgr
 
The difference is the FULL backup "misses" the /usr/openv/db directory
and it's files, while the DIFF/INCR does backup the /usr/openv/db
directory. So what's the big deal?

In a DR Exercise, you normally bring your FULL catalog backup with you
and recover the catalog from that FULL. What it does NOT put back are
the "Media Pools" that are outside the Netbackup default media pools.
This means that once your recovery of the catalog is done? You have
nothing but the standard default media pools and not your production
media pools for your backups and any RMAN backups.

Anybody seen this or know if I'm just off my rocker or is Netbackup
really missing part of the catalog for DR Recovery?

Inquiring minds want to know.
