No worries, I have an ordinary backup and wanted to try out the rolling
backup additionally ;).

The csync backup replication already works fine (well, apart from the
error messages mentioned in my other email). I just wanted to try out
the "sync_try_imap" option because csync was described as deprecated /
outdated in the documentation.

So, basically it's:

- setting up a common replication: use imap in favour of csync because
the latter is getting obsolete
- setting up a backup replication: use backupd w/csync

?

Probably I mixed up the replication types and thought of the backup as a
common replication with "extras".

Best,
