What's the current thinking regarding the best filing system to use for
an external USB backup disk?
That's a bit like asking which single engined aircraft is best for flying
the Atlantic. You talk about "your client": if they are a commercial
organisation, and they think that backups to a USB disk are a good way of
doing backups, I suggest that they need educating.
First question to ask them: When you did your last test restore from
backups, did you experience any issues?
+1. USB wasn't (isn't?) very well specified so there are reports of
buggy drivers. eSata could be another option to look at.
If they're unplugging during backups as you mentioned, they might do
better to mount the disk with the sync option, a separate issue from the
FS used. Better still try to provide a clear indication of when the
transfer has and hasn't completed.
When checking the last test restore take a look at the -c and -n flags
to rsync, don't settle for 'it seemed to work'. Good luck :)

Yes, I know a USB disk isn't the ultimate in disaster recovery planning,
but 'my client' isn't a multinational corporation, he's just the
self-employed bloke down the road.
I'll make sure it's using the 'sync' option for mounting.
