Re: [rdiff-backup-users] UpdateError on files that shouldn't have changed

I believe that happens when the destination file doesn't match what it backed up last time. This could happen when file system corruption has occurred on the server you're backing up to.

A large number of files are failing with the UpdateError ... does not match source error even though I know these files haven't changed since the backup started.
