What happens when you interrupt a backup process?

If I need to cancel a backup in the middle and I want to restart later (for example lets say I need to restart my computer but I am in the middle of a backup and I don’t want to wait for the backup to finish) can I just Ctrl-C and then resume the backup later. This is how I use rsync I just didn’t see anything specific about that for duplicacy.

How to properly do an initial backup to B2?

I started the backup again and it skipped a bunch of chunks at the beginning, but it still seems to be starting over at 0% and is only very gradually increasing. Does this mean the previous progress was lost, or will it skip the remaining chunks it already uploaded later in the process? I was expecting all of the skipped chunks to be at …

Sorry for the necro post, but I feel like this fits in here as a follow-up: what happens if you cancel a backup, adjust the filter to exclude more files/folders and then start again? I am assuming this will then leave chunks in the backup storage that will have to be purged later with -exhaustive?
