Thanks for the update Frank.

What do you think about standing up a small server to
host 2.0.5 and then use NFS to reach the destination

I know performance would suffer, but that would be
acceptable as an interim measure.  I might even be
able to get a 40GbE interface working between the
two hosts.  Sounds like fun!

Yes that is correct, you cannot directly mix rdiff-backup 1.2 and
rdiff-backup 2, for a number of reasons, mostly to do with issues with
Python 2 vs Python 3 and their networking.

However, this is also a fairly common issue, and really only affects
your rdiff-backup server (i.e. where the backups are stored), as the
clients only need a single version installed.

The current best practice is to have both versions installed on the
server, and some method of selecting which one the client needs.  The
issue is usually a packaging problem, as various ancillary files, like
man pages, or even the actual program, clash (i.e. both versions of
rdiff-backup).  For most common distribution a renamed and stripped
down version (i.e. leaving off documentation, etc) has been made
available, although I don't know if one was done for openSUSE.

If you want more details about this, you can find it here:

I should add that rdiff-backup 2.0.5 has no issues reading older backup
repositories, the issues are all around the network transport.

Hi Folks,

Longtime rdiff-backup user here.

I've got a couple dozen desktops and servers backing up
to a central server, all running openSUSE Leap 15.3.  Last
week I updated one of the desktops to 15.4 and now I'm
getting rdiff-backup errors.

I vaguely recall that version 2 broke backward compatibility.
Is that true?

Leap 15.3 has 1.2.8
Leap 15.4 has 2.0.5

If this is the issue, is there a workaround?  I've got almost a
of data floating around on these hosts and I can't instantly upgrade
all of them in unison.

The installs are all from the standard openSUSE repos. Maybe try to
install 1.2.8 on the newer Leap 15.4 system?

Any suggestions?
