Thanks for this. I was originally responding to Andrew's saying: <quote> There are many many ways to make take backups beyond having a disk big enough to hold the data. </quote> I can think of very few - and was interested in what he was thinking of. Incremental/differential backups are not really practical, since she will be at school. A periodic dd (or Clonezilla?) of the whole drive and more frequent updates of her personal data (of which I understand that there is not much) would be the optimum, but a trifle pricey, so I am still looking at alternative possibilities.
I wrote a script that only backs up our data directories (including much of /home) into a bunch of tarballs, excluding "junk" folders like caches, thumbnails, trash, etc, and compressing most but not stuff like image and OOo document directories.
Each backup goes in a separate, dated directory.For huge binary directories (like uncompressible video and audio), I simply do a "cp -vau" from the "live" tree to the backup tree.
The bottom line, though, is that *yes*, you *do* need enough disk space for the backup data.
