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.

No problem. Duplicacy will resume from the point it was interrupted.
