I agree with David. Shut the Linux system down. If you're only trying to backup _part_ of the Linux DASD, such as a file system for an application, you don't have to bring the whole system down for that. If you can get the application down and the file system unmounted (or mounted read-only), then you'll get a good backup of that file system. If the file system you're trying to backup is mounted read-write by _any_ guest, your backup will be potentially bad. (Some people have gotten away with doing that on occasion. It's definitely _not_ the recommended way.) Mark Post
