Netbackup Catalog (6.0) and Microsoft DFS-R

Has anyone tried to use DFS-R to replicate the Netbackup Catalog?  We have used it with a lot of success in other systems in our environment, and I was wondering if anyone has any input.  Our NBU mas...

    You will need to perform a hot catalog backup of the Sybase database or else you will have an inconsistent database and not be able to bring up NetBackup.  /usr/openv/db or %installpath%\veritas\db (I think on windows) is the location and has a script to perform a backup of database.

     

    We do a similar thing on a UNIX master, but perform a Sybase backup first (Volume and Device Database), then use rsync to get a copy of everything on an NFS mount. 

     

    A seperate thing but related to DFS-R.  NetBackup 6.0MP6 will NOT backup data in the replicated area with the DFS-R service running yet the backup will complete with a 0 status code.  It would back it up in MP5, but will not in MP6. If you are running 6.0MP6 on a server running DFS-R make sure you can restore the data.   BEWARE>>>>

I mean comfort that at roughly any given time, the "replicated" catalog data could be presented to a warm-standby server at another site beit for disaster recovery or a true disaster.  We would like to avoid using Storage Foundation for mirroring and may think of using some back end storage mirroring like flashcopy, but it seems that DFS-R would be nice and simple if of course it's reliable in this scenario.

 

Hope that explains where we're trying to go with it...
