Urbackup Server: on Docker v 2.5.32
Urbackup Client: 2.5.25.0

For the last few days i’ve been getting the below errors and there’s been a few /.datto folders leftover thats roughly 15G in size.

This is the log from the client

I have the exact setup and have the same error with Ubuntu 20 and Dattobd. I hope somebody can clarify this this situation.

I ended up uninstalling urbackup from this system then upgrading it to Ubuntu 22.04 then reinstalling it with LVM instead of dattodb. It seems to be working fine. I do get a few errors about it trying to back up sysvol but that’s something I’ll dig into further when i have more time.
