I am looking for some advice on options for replicating the catalog between our main site and DR site.
We have a netbackup master running NBU 5.1 MP4 (L Class HP-UX server) and the same spec machine running NBU 5.1 MP4 at the DR site. The method for replication should be appropriate for this level, but we are also looking for replication options if we upgrade both environments to NBU 6.
Currently we backup the catalog (22GB approx, compressed) to tape and then take the tape down to the DR site, the configs are wiped down at the DR site and we import the relevent images from the catalog tape etc and get the system available to start restoring data from. All backup policies are disabled so we simply carry out the restore jobs.
I am looking for alternative methods to make this quicker and easier - whether this means utillising a SAN based method to replicate data between the sites including information on how we accomplish it and things like frequency of replication and methods, whether we use something like Veritas Volume Replicator, rsync or other methods or whether upgrading to NBU 6 is a better option and why.
There is a 1GB pipe available for pushing the data through, so any thoughts on how I can best achieve this would be greatly appreciated.
