I’m running Duplicacy (on UnRAID) to backup about 2.6TB to a local drive. I have a remote (unRAID) share mapped to my host over WireGuard server to server. I have a maximum local upload of 40Mbps, everything else in the chain is 1Gbps. With no changes between local and remote it takes about 2 hours for a Copy to show completed. I assume it is doing a check each time to validate the data.
Is this speed typical? There’s no feedback in the GUI to show what is happening. Here is the time jump in the logs. Everything listed before and after completed in less than a minute.
