[rdiff-backup-users] rdiff-backup stopped working

[Michele]

Hi everybody.
I have a problem with my backup. I'm used to periodically run a backup
with rdiff-backup. Unfortunately a few days ago the electricity went
down for a few seconds, while I was running a backup. Since that time
I'm not able to make any incremental backup as I did before for a couple
of year without any kind of problem (God Save rdiff-backup!).
This is the error I get:

====================================================================

After I get this error I cannot list the backup increments (-l option),
until I run rdiff-backup with "--check-destination-dir". After that
rdiff-backup will correctly list the increments, but if I try a backup,
no hope: again the same error.
This is the script I run:


====================================================================
#!/bin/bash

DEST_FOLDER=/mnt/space/michele/Backup/home/michele/
SOURCE=/home/michele

rdiff-backup --exclude-other-filesystems --exclude $SOURCE/.thumbnails/
--exclude $SOURCE/.cache/ --exclude $SOURCE/.googleearth/Cache --exclude
$SOURCE/.Trash --exclude $SOURCE/.wine/drive_c/ --exclude
$SOURCE/.PlayOnLinux/ --exclude $SOURCE/Desktop/apt-mirror/ --exclude
"$SOURCE/Desktop/Da vedere" --exclude $SOURCE/opt/ $SOURCE $DEST_FOLDER

====================================================================

I really would like to continue using this set of backups, without the
need of starting a new full set (tons of giga).

Any idea?
Thanks,
Michele
