Hello,
we have problems with the urbackup client. A full image backup is possible without problems, but the incremental backup does not work. The backup always aborts exactly after 2minutes and 2 seconds.
The clients are running Windows Server 2022 the server is the latest Docker Image 2.5.27 running on Linux.
We currently do not see firewall and network issues as the full backup works without any problems.
What could be the cause of the problem?
Here are the client logs:
Starting unscheduled incremental image backup of volume “C:”…
Image backup is based on the last full image backup.
Failed to exchange data with client while preparing image backup. Connection to the client interrupted.
Time needed for client backup -------: 2m 2s
Backup failed
Here are the server logs:
