Well, My home computer is loaded with 3TB of data (a few GB for the
system, all the remaining for audio, video, photos, emails & a bit of
povray... I do not want to bother managing the space: until I delete it,
I want to be able to retrieve it )

Backup on external virgin drive took more than 2 days to perform.
(and so far, I'm lucky, 3TB external drives do exist, and rsync is able
to continue from previous run)
updating backup (using rsync) take less time (but still a bit), but I'm
lazy so I do it once in a while. Nevertheless, I want to be protected
against a single drive failure (and as I do not want to manage the
space, I had to just see "one big space", so raid was already an option,
such as raid0 (concatenation of all disks as a single partition)).
So, instead of 5 disks, I bought a sixth one and setup a raid-5.
increase of disk prices is about the VAT, I can pay it twice for such
comfort... (and it was before the water over the factories in Asia, so
prices were even cheaper than a few months ago)

Now, would I split the backup across multiple backup drive ? Not as a
starter. I probably will have to do it one day, but it will bother me to
actually have to manage the directories (which one is big enough to fit ?).
