The above is quoted the following thread on the rsync mailing list : http://www.mail-archive.com/rsync@lists.samba.org/msg26679.html I figured that this information may be useful to people who are considering the use of lbackup or are simply looking for a full system backup solution. _______________________________________________ lbackup-discussion mailing list http://www.lbackup.org Change options or unsubscribe : http://lbackup.org/mailing_lists
