I’ve been using Duplicati, and just recently came across Duplicacy. It is a really exciting piece of technology. There are some neat things I’m attempting to do, but I thought I’d first check with more experienced users what I should anticipate in each case.
I have folders on multiple machines that are (instantly, always) kept in sync by rsync. However, file permissions, user/group ownership, and possibly other extended meta-data might be different. For the two scenarios:
- If I start duplicacy on
1a) the initial upload is interrupted, can I resume the upload from
machine2? If so, do I gain by
.duplicacy folder to
machine2 before resuming?
1b) the initial upload completes, can I do future backups from either
machine2 with indistinguishable results on the remote storage?
- I’m thinking of speeding up the initial upload by doing it on both machines, each responsible for a subset of
SubFolder1–4 under my
RealRepository. That is, I set up
machine1's repository to contain
machine2's repository to have
SubFolder4. These are symlinks to the corresponding ones under
RealRepository. Once the upload completes, I do a final round of backup by having all subfolders symlinked in. Based on my understanding of how Duplicacy works, the final upload should be very quick and use up little additional storage — is this correct?
