Snapshots are read-only. I think storage checkpoints would be more appropriate. Then you could perhaps run your DR test on the checkpoint. When you're done, toss the checkpoint and come back up on the regular (untouched) filesystem. > I suppose I could hack something up with rsync, but that would probably > be almost as time consuming as just copying the snap volume data back to > the main volume. I'm not so sure. rsync should be pretty good about skipping portions of a file that are identical, so it might be quite useful. Also, rsync is really worst when you have lots and lots of files. In a DB test, you probably don't have all that many files. -- Darren Dunham [EMAIL PROTECTED] Senior Technical Consultant TAOS http://www.taos.com/ Got some Dr Pepper?
