[rdiff-backup-users] Error recovering from failed backup

[Keith Edmunds]

I have a server being backed up by rdiff-backup, and occasionally the 
backup fails for network or other reasons. The problem I am experiencing 
happens on the _next_ backup. The command issued is:

--------------------------------------------------------------
        rdiff-backup --print-statistics --create-full-path \
                /home/xxx \
                backup::/backups/yyy/xxx \
--------------------------------------------------------------

Then I get, as expected:

--------------------------------------------------------------
Previous backup seems to have failed, regressing destination now.
--------------------------------------------------------------

Followed by:

--------------------------------------------------------------
Warning: Could not restore file /backups/yyy/xxx/02LaidOut/.DS_Store!

A regular file was indicated by the metadata, but could not be
constructed from existing increments because last increment had type
None.  Instead of the actual file's data, an empty length file will be
created.  This error is probably caused by data loss in the
rdiff-backup destination directory, or a bug in rdiff-backup
-----------------------------------------------------------------

Note that the source directory name is '02 Laid Out' but that the spaces 
have disappeared in the error message (but the spaces do exist on the 
backup:: machine). The exclamation mark at the end of the error message 
is part of the message rather than part of the filename. Both source and 
destination machines are running Linux with rdiff-backup 0.13.4. The 
files being backed up are created by Apple Macs and saved in an 
Appletalk share.

Any clues as to how to proceed?

Thanks,
Keith
