Been using Duplicacy for over a month now on Windows 10 with B2 cloud storage. No issues! I have been doing a “check -chunks” twice a week (Tue & Sat) along with a purge twice a week (Wed & Sun). I’m wondering how much data bandwidth on B2 I’m using by doing this check operation so often. My charge for bandwidth usage on B2 was higher than I expected.
I know Duplicacy keeps a list of verified chunks and only checks new ones.
Does it download the entire chunk? Isn’t this the same as downloading everything I have backed up since the last check? That would be a lot of bandwidth.
Am I understanding how much bandwidth is being used by the “check -chunks” operation correctly? Is it downloading all new chunks, or only a portion of those chunks (if that’s possible)?
I decided to change my schedule to do a “check” without the “-chunks” option and to do it only once a week. I figure just knowing the files are on B2 is good enough, I don’t need to download them.
