Thanks, I generally use dump as a cron job to do full backups every day (during off-peak hours) For this, it works great. If you're filesystem won't fit on a single tape and/or there is some other reason you can't take this approach, dump does offer options for incremental backups, I assume this is the "algorithm" you're talking about. It can be a little confusing. Also, dump handles multi-tape backups well. I have one client with a HUGE filesystem setup to rsync to a staging (backup) server during off- peak hours. The sysadmin can then backup to tape at his leasure during the day. The backup always comprises at least 2 25G DATs, and sometimes three. amanda is a possible option if you have more complex needs. It's in the ports. I haven't used it so I can't really vouch for it or not. There is also a commercial product available called BRU. I've not used it either (so I can't give an opinion) but you can find out more by searching http://mall.daemonnews.org Hope this helps, Bill -- "Where's the robot to pat you on the back?"
