Thanks in advance, -Ray The original guide (that I know of) for doing disk to disk backups with rsync can be found here: http://www.mikerubel.org/computers/rsync_snapshots/ Then there's dirvish which I think it based on that method: http://www.dirvish.org/ Next there's rdiff-backup, which can be found here: http://www.nongnu.org/rdiff-backup/ I think there are some other rsync-related backups too. I hear good thing about the backup pc project. http://backuppc.sourceforge.net/ ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

There are simply so many different ways one could implement a backup strategy depending on hardware available, what software you're comfortable with, whether you want to script your own or use a backup package, the type of data you need to back up etc. The *important* thing is that you're comfortable with your backup procedure, it meets your needs, it's performed regularly, it's tested and it works. Hi Ned, Thanks for the thoughtful reply. I've cloned the OS drive already and it is safely locked away. We're an entirely off-internet system, so updates aren't even a problem. The issue is the user data and with what you and others have written, I'm considering doing a local rsync to a second set of mirrored drives already in the box (but as of now disused).

Keep in mind that certain hardware, software, or operator errors (or a building disaster) can wipe out all of the disks at once. A safer approach might be to rsync to external disks that you rotate offsite or to rsync over the network to a different location. -- Les Mikesell [EMAIL PROTECTED] ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
