Re: Can I interrupt an rdiff-backup backup?
Hi, it's still not quite enough information to be sure what you're trying to do, but you are aware that you can install rdiff-backup on Ubuntu as well as Windows, enable SSH on Windows, as to remotely backup Windows without going through a Samba drive? It might not be the best approach for your use case, but what you should definitely avoid is to use Samba _and_ the remote feature of rdiff-backup, as you would incur twice the network induced latency. A short explanation of which command you're calling where would help us help you.

Re: Can I interrupt an rdiff-backup backup?
Hi Robert Thanks again for your quick response and thanks to Eric also. I took your advice and deleted the whole directory. That worked! It wouldn't have occurred to me that the *rm -rf* command would not work on the rdiff-backup-data directory directly but issued one level up, would work?! Anyway you don't look a gift horse in the mouth :). FYI both the server and the client are running Ubuntu 22.04. It is a Samba network. This is because I can't wean my wife off of Windows, so I need to be able to connect a Windows 10 machine to the network. I'll start the 3 day backup again. Even if the rdiff-backup backup gets corrupted at some point, the actual data is still accessible, so it seems worth the small risk. I'm not sure why my machine closed halfway through, but whatever the reason, it's unlikely to happen again, so worth a second try IMO.

If one of these failed could it take 3 days to roll back to the previous night? That depends. Let's consider two extreme cases: (A) The machine being backed up is very small, but the backup is being done over a 56 Kb/s dialup connection and it takes 3 days to send the data for that initial, complete backup. (B) There are nearly a billion files totalling nearly 900 terabytes, and just writing that much data to a disk takes 3 days. For case (A) the regression on the server would be quite fast. For case (B) it could take more than the 3 days it took to write the backup originally (and that could be true even for regressing a small incremental backup on that huge archive). -- Bob Nichols "NOSPAM" is really part of my email address.

Re: Can I interrupt an rdiff-backup backup?
Hello Mike, Rdiff-backup is resilient to failure and will recover if the backup process gets interrupted. To help you understand why nothing happens when you start the backup, you might want to increase the verbosity of rdiff-backup by using "-v" something like "-v 5" or "-v 6" should help you understand why rdiff-backup is doing under the hood.
