Server 2.5.22/Client 2.5.16 - Can not create virtual subclients

I am using urbackup for years and had no problems so far.
Yet, I have updated my linux server to the latest beta release (2.5.22) as I need xtrabackup for backing up mysql-databases.
Now I tried to add a new linux client using client version 2.5.16.

Everything seams fine expect it is not possible for me to create the [incr]-subclient for that machine used for incremental xtrabackups.
I have adjusted the /usr/local/etc/urbackup/mariadbxtrabackup.conf accordingly and executed /usr/local/share/urbackup/scripts/setup-mariadbbackup. But no luck, the server did not accept the virtual subclient setting of the client. I also tried to create the virtual subclient via the webinterface of the server. But also, no luck.

Does anybody have an idea what I am doing wrong? How can I create a new virtual subclient on S-2.5.22/C-2.5.16? Should I use an other server/client version-combination?

Kind regards

It might not work yet (virtual sub clients – need to reproduce). Meanwhile could you perhaps attach a debug client log as described in Having problems with UrBackup? Please read before posting ?

Thank you for your quick reply!

I have attached a server and client log (both debug-level).
Before creating this log files i have removed the client (atlas) from the server and did a “urbackupsrv cleanup” to really remove the client from the server.
Than I started with a fresh client installation, modified mariadbxtrabackup.conf and run the setup-mariadbbackup.
In the server and client logfiles you can see that xtrabackup is running and doing an full backup from the main-client. Also one can observe, that the setup-mariadbbackup tries to create the virtual server [incr] for atlas but this virtual client did not show up in the webinterface and also the entry virtual_client=incr has been removed from /usr/local/var/urbackup/data/settings.cfg.

Do you need additional infos?

Kind regards
