List, hello,
We have different machines for (i) our mail-server, and for (ii) a
backup of that mail server's mail storage. Under cron's control,
rdiff-backup uses a remote ssh login from the mail machine onto the
backup machine to make each backup of the mail store. We've just
replaced our mailstorage backup server with a new-build Debian system
equipped with bigger discs; the existing backup data has been copied
(rsync) into the same directory name but which is now mounted under
/srv. The mail system server remains as existing; the new backup
server now has a different IP address but still on the same local
subnet. rdiff-backup is version 1.2.8 on both machines.
But I must have done something wrong in the new set up. The first
attempt to check that mail backup would continue working failed with
Exception 'Found too many current_mirror incs!' raised of class '<type
'exceptions.AssertionError'>':
The rdiff-backup command (same as before but with different IP
address, and with '/srv' added at the destination because the backup
storage is mounted under /srv on the new machine) is:
rdiff-backup --print-statistics -v3 /Data101/vmail/
ron@192.168.0.201::/srv/Data/101vmail
The error report in full is:
Exception 'Found too many current_mirror incs!' raised of class '<type
'exceptions.AssertionError'>':

Using straight ssh login to ron@192.168.0.201 enables
$ cd /srv/Data/101vmail
without error, and
$ ls
lists all the directories and files that should be there, plus the
radiff-backup-data directory. So the remote ssh login looks ok, and
the name of the destination directory look ok.
Using a check-destination-directory command from the mail server
# rdiff-backup --check-destination-dir
ron@192.168.0.201::/srv/Data/101vmail
results in the same error report as above.
I am not sure what to check to find what might be causing this. Has
anybody else seen this error before?
Honestly, any ideas would be really welcome.
regards, Ron
