I note that I forgot one key point: the drawbacks of ext3.

ext3 is the most stable filesystem I have dealt with; it copes better
with corruption after the fact as well as resisting it during runtime
well.[1]

It is a passable all-round performance in terms of performance, but is
*not* the fastest filesystem out there in 'ordered' data mode.[2]  You
will find that other filesystems, especially reiserfs, consistently
outperform it at most tasks.

Er, except file deletion, since everyone else seems to fall flat on
that, while ext3 just keeps chugging along, for some reason.

Footnotes: 
[1]  I found this out the hard way, by having a faulty IDE cable that
     would cause intermittent corruption of blocks on my disk. Ah, the
     fun we had.

[2]  This is the default mode. data=journal is no real use for the way
     BackupPC operates, and data=writeback is ... not worth the overhead
     of journaling in my opinion. It makes ext3 the same as XFS in terms
     of write assurances, but gives random block content rather than
     zerod data.
