backups I use a nice big usb disk drive,
Note that these scripts are mostly pretty customized for my system, but can serve as examples of how to do backups that you can modify for your own system.
One of the nifty features of
Naturally, this will eventually fill up the usb drive, but I manually remove the old backup directories when the disk starts getting full. Usually there is plenty of room to keep a month or two worth of backups.
I run the backup script every day by simply making a symlink in
The rsync-exclude perl script is where most of the customization lives. It "just knows" how my various disk partitions are arranged, which files I want to backup, etc. In particular, there are several versions of linux on this box, and I back up all of them (or all the useful ones anyway), by backing up the root trees from the places where I have them mounted and excluding the same subdirectories in those roots that I exclude from the current system's root.
Since backups are kind of important, it is also important not to have them corrupted or deleted if you can help it. One thing that can help is the Hide Disks web page which explains how to keep hal from automatically mounting the usb drive any time anyone logs in.
