Warning: Error setting file time of

Hello,

After the file backup is finished, I get the following messages:
Error setting file time of …

This takes then a few minutes and in the protocol then over 50000 such messages.
The protocol comes by mail and is then so large that it can barely open.

Can this feature be disabled?

Backup Server:
Urbackup 2.1.19 Ubuntu 16.04
Client Windows 2012 Server
Synology NAS for Backupfiles, mounts via smb on Backupserver.

Is the same as here, but I can not ignore that:

Thanks
Tobias

6 years later and I am having the same warnings. I have the same setup as the OP but newer OSes.
Wondering where this can be disabled.
P.S. Still a great product.
