I have tried a many things andeither I cannot understand how to use them or they simply don't actually work. I will therefore return to a manual system of occasionally writinga zip archive of my home drive to the external drive. It works but is tiresome and has a number of problems.I'd do it this way, assuming your drives have enough space and are linux-formatted. Create a directory for every partition you want to back up. Then write a shell script that repeats this for each: cd /partion_top # examples / /boot rsync --one-file-system -avH . /path/to/destination/directoryThis will take a long time the first time you run it. Subsequent timeswill be fast enough that you probably won't bother scheduling or automating it - just run it in a window where it won't interfere withanything else you are doing. Once you understand what it is doing, youmay want to ad the --delete option to remove files that have been removed on the source and perhaps do something with the --backup-dir option to keep some history of changing files. You'll end up with a full copy of all your files in a form you can simply copy back into place if you need them.
I'd say rdiff-backup is about as easy (the docs are very good, lots of examples) and that gives you the added advantage of having multiple incremental backups (like Time Machine).
