Hey everybody,
I stumbled upon this thread, because I recently setup an Unraid server and have an old Syno Box, which I want to backup to the Unraid Box.
So I followed @bung's post here. It seems to work, because when I input my info into the rsync dialogue the Backupmoduels from Unraud are loaded, here "backups" (screenshot).
However, when I click continue (after choosing the backup sources) I get an error message like "This operation cannot be carried out. Please try again later."
Does anyone have an idea how I can fix this, or even in what logs I might find some info on the exact error that is occuring?
