Hello:
Sorry to dig up an old thread, but I think I’m seeing the same issue as the OP:
I’ve just started evaluating UrBackup (looking like a nice project - thanks all!), and am running the server on a Synology NAS (hosted in a Docker container) connected on the LAN to a macOS client (running inside a VM for testing purposes).
Backups are running successfully - but I seem to be getting a full transfer when I wouldn’t expect it: to test, I’m duplicating the Xcode application (a 10.38GB bundle) and running an incremental file backup. I have Settings > Advanced > Local incremental file backup transfer mode set to Block differences - hashed - but every backup seems to transfer the full ‘new’ data.
I’ve also tried with Hashed - but in any case I believe this is related to the transfer method, rather than being a local version of Settings > Internet > Calculate file-hashes on the client.
Here’s the most-recent transfer log from the server:

Like the OP in [request] Generate hashes on client for local network? I’m going to be backing up a number of machines with largely-static media files - some will be being moved around between folders - and it would be good to keep the network traffic to a minimum.
Is this currently expected behaviour?
EDIT: Sorry - forgot to include versions: Server 2.1.20, Client 2.1.17.
Thanks,
Pants.
