Urbackup fails (SYSVOL partition failed)

Server
1

Hey!
I installed an urbackup Server on Debian 9.5 a few weeks ago.
On my machine I just realized that my Windows 10 machine hasn´t done a full image Backup, so I forced it to do a Backup.
As this fails I started debug mode on my Client. Do you have any ideas what to do? Thank you!

Which client version are you using?

3

I´m using Client Version 2.2.6.

I think I already fixed that problem, but didn’t merge it to 2.3.x yet (and the fix isn’t in 2.2.6). It’ll be fixed with the next 2.3.x client version, I guess.

Well, I just downloaded 2.3.1 beta and it seems to work! Thanks!
Keep up the great work! Cheers!
