Full File Backup stucks at 100%


I have UrBackup 2.2.11 and 2 laptop clients (planning to add 2 more PC). Image backup is working fine. The problem is in full file backups - files are copied and when client reach 100%, process stucks on INFO Waiting for file hashing and copying threads… This status may be for a few days and nothing happen.

On 2nd client process was finally finished (or not), but the backup size is indicated on -1.

The server located is on Debian 8 and all clients on Windows (currently 2x Win10, want to add 1xW10 and 2x W7).

Hello, what are OS on clients ?

Both Win10
