Uhhhhh,,,,unless you're unmounting them first, this isn't really safe. You know that, right? Your Oracle backups are probably OK (since you're explicitly halting IO and you're flushing the disks first, so although the FS is dirty there's really little chance of it ACTUALLY being corrupt), but your system images aren't. Client 2 is a much better idea. Now, if you can arrange to UNMOUNT the fses you care about on client 1, you'd be fine. But that probably requires out-and-out stopping Oracle rather than just quiescing it, so no process has open files on the volume. If you can't do that, I'd do the client 1 thing, and then mount the snapshot volumes r/o, fsck 'em, and then back those up with a file- backup utility.
