I've tried that with backing up to tape. Unfortunately, any disk activity which goes on at the time you're trying to copy that data, will kill the disk performance. I found that it was 4x faster (12 hours instead of 48 hours) to just quiesce the machine (i.e. stop backuppc) and make the backup, than to try to make the backup of a snapshot on a live machine. It may not be as bad with disk backup; the problem with tape is that it has to stop, rewind, and restart every time it doesn't get data fast enough. The general point I'm making tho, is that snapshots of a live, active system *do* slow things down substantially. -- Carl Soderstrom Systems Administrator Real-Time Enterprises www.real-time.com ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
