A lot has been written lately about rsync and incremental backups. I'm going to preach against both of them.
Yes, a few years ago, when drives were expensive (iirc, my first one gigabyte drive, back in '95, cost me about $600) and connections were slow, some of us had to exercise the tradeoff between incremental backups and full backups. However, if you make incremental backups, for example, from the first of the month, and your system gets hacked on the 29th, you have to restore all backups from the first before your system is operational again. If you use rsync, it's even worse; you probably don't have unifected files. May I suggest: Sunday 2 am (the Internet isn't too busy then) back up your entire system and save it to the Sunday directory, overwriting last Sunday's backup. Monday 2 am back up your entire system and save it to the daily directory, overwriting Saturday's backup. Tuesday 2 am back up your entire system and save it to the daily directory, overwriting Monday's backup. Wednesday 2 am back up your entire system and save it to the daily directory, overwriting Tuesday's backup. Thursday 2 am back up your entire system and save it to the daily directory, overwriting Wednesday's backup. Friday 2 am back up your entire system and save it to the daily directory, overwriting Thursday's backup. Saturday 2 am back up your entire system and save it to the daily directory, overwriting Friday's backup. That's a lot of storage, but considering the options, it's certainly affordable. And it should give you enough time to find out you need a backup and still have a reasonably recent one you can restore quickly. On RaQ3 and RaQ4 systems we maintain our systems as closely to each other as possible, and use CMU for our backup, adding mySQL and dns before we tar the resulting directory structure. On other systems, or for more granular control, you may decide to back up differently. And oh, always test your strategy... there's nothing quite as bad as having backups you can't restore from.
