The first step in figuring out a backup strategy is to decide on the media. I.e., will you be backing up to an external USB disk, a network disk, optical media, over the internet to a web based service, or what? The second step is to decide how often you want to back up and whether you want it automated or not. The reason you do steps one and two first is because most software packages were originally designed for one type of storage device and, while the current version of the software may be able to use various devices, you'll find a better fit if you choose software that is optimized for the media you have chosen. Ditto for the frequency of the backup, as some packages have a nice built-in GUI scheduler, while others require Cron. I once tried to figure out Cron and it was hopeless - incredibly powerful tool, but equally difficult to learn. I am currently using an external hard drive that swaps in and out with the optical drive in my laptop. Most of the time it sits in a fireproof file cabinet in my home, and I insert it when I am ready to do a backup. I don't schedule my backups because sometimes weeks will go by when I have created nothing important. And when I am working on a project that has not yet been backed up I use a 4 GB USB stick and just copy the folder to it every so often as I complete a major part of the project. For the hard disk backup I use rdiff-backup. I started with Pybackpack, which is a GUI front end for rdiff-backup. Over time I figured out enough about how rdiff-backup works to create a little bash script to run my backup. I just put a launcher in my Gnome Applications menu to run the script. To do an entire backup to the hard disk involves retrieving the hard disk from the file cabinet and inserting it (it auto-mounts), then click on the script launcher. I generally do this at night and in the morning the backup is done. _______________________________________________ PLUG mailing list [email protected] http://lists.pdxlinux.org/mailman/listinfo/plug
