I get error messages about things like network errors BackupPC encounters during backups. The error you're having doesn't sound like 'regular error' though and that's probably why you get irrgular behavior (hanging processes). Either you've hit a bug in BackupPC or your installation is broken, but that undefined value error shouldn't occur. Did you install BackupPC using a package manager? If so, can you verify the installation (e.g. rpm -V BackupPC if you installed an RPM)? > and without even doing something like skipping the troublesome areas > and > moving on. Now that would be scary: would you like incomplete backups? Nils Breunese. P.S. Backing up MYI and MYD files of MySQL databases is not very useful, as they're not guaranteed to be in a consistent state when you back them up. Even if you backed them up succesfully you could have corrupt databases after restoring these files. Better create SQL dumps using the pre-dump command and backup those. ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ BackupPC-users mailing list BackupPC-users@lists.sourceforge.net List: https://lists.sourceforge.net/lists/listinfo/backuppc-users Wiki: http://backuppc.wiki.sourceforge.net Project: http://backuppc.sourceforge.net/
