This would be a huge win I think. We do something similar with our mail system (NFS mounted to a NetApp). We quicese all the dbs (bdb essentially) and execute a snapshot. Takes mere moments. Then we backup from the snapshot. This allows us to perform a multi-hour backup without having to take the mailsystem offline at all. To be able to apply this to other systems, especially ones that wouldn't even know any better (UFS, NTFS, etc) would certainly be a nice way to go. In fact, I'll have to try this on the XP box on my desk that mounts iSCSI zvols the next time I'm in the office. ;) -brian -- "Perl can be fast and elegant as much as J2EE can be fast and elegant.
