Mark,
Do any of you take snapshots during the day like this?
Yes but.... 1. I'm on UD so apologies, this post is probably useless to you, however the process is the same. 2. Our process is sync, dbpause, sync, take snapshot, dbresume. Total time is < 2 seconds. We take snapshots every 2 hours during the day and the process is invisible to the users and has no system impact. 4. We are using linux commands to signal the EMC san to take the snapshot rather than using o/s level snapshotting, although once we get our last servers up to RHEL4, the snapshotting function in the Linux LVM is something I'm keen to experiment with. 5. The luxury of the san snapshotting is the server itself is not affected at all and depending on the san configuration, the snapshots can be made persistent so they survive a power outage. I'm going back a few years now but iirc solaris snapshots were lost on a reboot. HTH (comments above about different o/s and database not withstanding).
