I’m not sure why the original download was truncated. It was surprisingly slow to download 51GB over Gigabit Ethernet. Maybe an hour in total. SMB would have been transferred in seconds. So maybe it was just interrupted.
The folder starting ? is very odd. It is still functional and now backing up the repaired remote client.
Can I query the database and find the path from there? Maybe that will give me a clue.
Update: I just had to remotely reinstall the client as it was showing authentication failure on the server status page.
I copied the computer name field from the client and pasted it into a hex editor.
It’s just spaces at the beggining…
I have created a new client and it’s now backing up fine to a visible folder with no odd characters.
Thanks again for the help.
