[rdiff-backup-users] Files Missing In Backup Resulting in Update Error

[M. Verkerk]

Dear all,

Thanks for this script! Really fills the gap between rsync and more advanced backup tools! I ran into some trouble I hope to find some help here!

I’m running rdiff-backup with the following cronjob script:

—Cut--

#!/bin/bash

if [ -e /tmp/backup-XXX.lock ]

then

        echo "Previous backup still in progress! Bailing out!";

        exit 0;

fi

echo "Setting lock file!";

touch /tmp/backup-XXX.lock

echo "Backing up etc!";

nice -n -3 rdiff-backup --print-statistics /etc YYY.domain.nl::/data/backup/XXX/rdiff-disk-backup/etc;

echo "Done!";

echo "Backing up home!";

nice -n -3 rdiff-backup --print-statistics /home YYY.domain.nl::/data/backup/XXX/rdiff-disk-backup/home;

echo "Done!”;

echo "Removing lock file!";

rm /tmp/backup-XXX.lock;

echo "Done!";

-Cut-

During the last backup I got several UpdateErrors with seemingly random backup files (just including three):

—Cut-

UpdateError 529841/top100000.txt Updated mirror temp file /data/backup/XXX/rdiff-disk-backup/home/529841/rdiff-backup.tmp.265 does not match source

UpdateError marijn/src/perl-5.16.1/x2p/s2p Updated mirror temp file /data/backup/XXX/rdiff-disk-backup/home/marijn/src/perl-5.16.1/x2p/rdiff-backup.tmp.4011 does not match source

UpdateError 529841/FVC/Meta_all/ecrhs_ALL1.txt Updated mirror temp file /data/backup/XXX/rdiff-disk-backup/home/529841/FVC/Meta_all/rdiff-backup.tmp.231 does not match source

-Pase-

The files mentioned here ARE existing on the backup source drive with no peculiar ownership or permissions. Somehow they are NOT on the backup folder - they should have been, some of the files are there and not changed since we start using rdiff-backup. I think the error message is indirectly related to the problem. Could this be a network failure - as you can see in the script we are using ssh?

More important: what can I do to trigger the rdiff-backup to reconsider en copy these omitted files?

Thanks very much in advanced!
