Re: [Veritas-bu] RMAN and NetBackup Question
RMAN and NetBackup each has a retention and one can normally restore from a backup that has expired from neither. (One can add back a unexpired NetBackup image into the RMAN catalog, as one can import a tape image back into the NetBackup catalog) RMAN does not know the Netbackup retention nor does NetBackup know the RMAN retention. There are RMAN commands to bring these into (momentary) sync, deleting items in the RMAN catalog or control file and NetBackup. For example, I use (on my tapeless system) these RMAN commands, weekly: - delete noprompt obsolete device type disk; - crosscheck backup; - delete noprompt expired backup device type disk; It should be noted that RMAN retention policies can be more complex than, or different from, Netbackup's simple keep for n days. I have no clue how RMAN could change its mind unless somehow the control file and RMAN catalog were different and one query used the catalog and the other didn't.

Re: [Veritas-bu] RMAN and NetBackup Question
Hi, The retention set on the master server ultimately decides how long it is on tape, if there is a discrepancy between what the RMAN catalog server thinks and the netbackup master server thinks, then that could be one of the problems. Does/do your DBAs know what retention you use? Justin. On Fri, 13 May 2011, Patrick wrote: Thank you all for the fast replies. I don't have access to the Oracle servers so I have to rely on the DBAs.
