I think amanda or bacula (or both) have a mysql backup program as an extra that will perform an incremental.
For mysql, it has a bin file system that can be rotated daily, hourly, whatever with a full dump only needed when you want (once a week?) so I would just grab the bin files I think. When I figure this out, perfectly, I should post it all so others can have a backup solution. I have over 40 linux books and not one really goes into backups. They mention them, but no working examples of merit. _______________________________________________ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos
