Dirvish <http://www.dirvish.org/>. The docs are a bit obtuse, but the help on the mail list is outstanding. I switched from tape to an external, USB hard drive (300G currently) and use dirvish running daily from root's crontab. I used to make weekly full backups and daily incremental backups; now each night's backup (using rsync) are the changes from the night before. You can restore the system to any prior state (or restore individual files) as long as you have them on the drive. You can exclude filesystems (e.g., /tmp) where files disappear so they don't have a revised version for dirvish to find and copy. You can set expiration periods however you want; I keep daily backups for 2 weeks and full backups for a month. Keith keeps everything forever. While you'll spend time getting your head around how it works and setting up banks (hosts), vaults (filesystems), the initial storage drive directory setup, and initial images, it's worth the effort. Once that's done you'll have complete images of your systems ... as long as you remember to turn on the backup drive each evening. :-) Rich _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
