Yup!  I am aware of that, but thanks for reminding me.  My backup
strategy, such as it is, is to have *all* my data on my main machine hard
drive (including photos etc.) and an external USB drive mirrored with
rsync.  It is suboptimal in that it doesn't maintain historic snapshots,
but I am aware of the limitation I have imposed on myself.  Since hard
drives fill up over time I move all my data onto a new hard drive when
it's full, and get a new external drive.  That means that the old drives
themselves are historic snapshots.  The DVD copies are intended to be last
ditch backups if I lose the laptop, the backup drive and the most recent
retired drive.

Oh, and by the way, I like using rsync for this as it means I can look at
the directory tree on the backup drive verbatim, and not compressed up
into some notional "backup file".  For our readers at home using XP I
recommend Microsoft's SyncToy power tool.  It's basically rsync with a
GUI.

Best wishes,

Andrew
