Home -> Community -> Mailing Lists -> Oracle-L -> RE: Shadow Image....
We have HDS 9960 and are thinking backup via shadow image.
Can someone who is using this provide us the steps to do
both backup and recovery?
Thanks. (Solaris 9 / Oracle 9.2.0.4.0)

The rumors of the conventional backup's demise are absolutely true and the corpse should have been buried a long time ago...
RMAN works quite well with those techniques (i.e. file-system snapshot, BCVs, shadow image, etc). First CATALOG DATAFILECOPY the snapped images to enter knowledge of their existence into the RMAN catalog, and then use BACKUP DATAFILECOPY to backup those copies onto tape. Admittedly not as straightforward as simply issuing a BACKUP DATABASE command, but that's what Perl and shell scripts are for, but the restore and recovery is no different. You get corruption checking and the ability to validate recoverability -- things that old-style scripted backups don't provide.
The DBAs still have to put the database into and out of BACKUP mode during the snapshot, but getting it to tape and -- much more importantly -- having an easy time during restore and recovery -- is best done with RMAN.
Yep, deader than roadkill. Better bury it before it stinks up the place...
