Yes, I think I backup everything important every night, with BackupPC.

What is strange is that I don't recall any episode
that might have corrupted the partition table.
I run smartd on this machine; 
and according to "sudo smartctl -a /dev/sdb"
everything seems fine with this drive, no errors reported.
(I'm a bit wary of running "smartctl -t" as I'm not in the same country
as the machine at the moment.)
