[rdiff-backup-users] Re: IOError: CRC check failed

[Brad Beyenhof]

In thinking about this more, the initial successful backup was
probably using rdiff-backup 1.2.3 (that was what was current in
December, correct?), and the recent failure was with 1.2.5.

Hopefully that helps with the diagnosis...

Space isn't remote at all. It's only an hour's drive away if your car
could go straight upwards.
