[rdiff-backup-users] Trying to backup and restore root-partition...

[Oliver Kaltenecker]

Hello,

I'm new to rdiff-backup and tried to find an answer for the following 
problem in the archives but didn't find an answer yet:

I'd like to backup a linux machine (client) with two partitions (e.g. / 
(root) and /srv) to the backup-server (server) and restore the two 
partitions completely in case of a failure.

For backup I invoke the following commands on the backup-server:

for /srv: rdiff-backup --force \
                       --print-statistics \
                       --exclude-device-files \
                       --exclude-other-filesystems \
                       client::/srv \
                       /mirror/client/srv

for /: rdiff-backup --force \
                    --print-statistics \
                    --exclude-device-files \
                    --exclude-other-filesystems \
                    --exclude /dev \
                    --exclude /srv \
                    client::/ \
                    /mirror/client/wurzel

For restore I do the following:

for /srv: rdiff-backup --force \
                       --print-statistics \
                       --exclude-device-files \
                       --restore-as-of now \
                       /mirror/client/srv \
                       client::/srv

for /: rdiff-backup --force \
                    --print-statistics \
                    --exclude-device-files \
                    --exclude-other-filesystems \
                    --restore-as-of now \
                    /mirror/client/wurzel \
                    client::/

The restore of the srv partition works well but the restore of the root 
partition throws the following error messages:

    raise ConnectionReadError("Truncated header string (problem "
rdiff_backup.connection.ConnectionReadError: Truncated header string 
(problem probably originated remotely)



I tried various combinations of --include ... and --exclude ... but 
cannot restore the root partition.

Am I missing something or am I completely wrong in trying to restore the 
root partition?

Any help would be greatly appreciated.

   Oliver.
