I would recommend this as well. It also has the benefit of improving read performance as well. Otherwise I would recommend a simple dd of the backuppc data partition to the backup disk. This would be fastest, but does require that your backup disk be at least as big as your backuppc data partition. -Dave ------------------------------------------------------------------------- This SF.net email is sponsored by DB2 Express Download DB2 Express C - the FREE version of DB2 express and take control of your XML.
