For regular backup I use dar and if I need to copy a whole disk I use mirrordir -- ZekeVarg <[EMAIL PROTECTED]> -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?

Hard Drive Going - Need a good backup utility
Title: Message The boot drive of one of my systems is going. I would like to make a copy to CD or a Disk to Disk copy. It has many partitions and I would like to preserve them seperately or at least be able to recreate them painlessly.

By ignoring the filesystems on the failing drive you excerise the drive less. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble? Contact [EMAIL PROTECTED]
