I’ve been searching, but I haven’t found an answer for this - at least not one I’m comfortable that I understand completely, and I don’t want to take risks on something this important. First, my basic setup is that I have 2 Unraid servers in separate zones on my home network, and I’m running Duplicacy on both. Key files on each are backed up to the other via Duplicacy.
One area has been a concern for me - my Media folder. It represents about 8TB of movies, music, and pictures. The initial backup took days and follow ons have been much faster, as expected. If I had a failure, however, it would take forever to restore so I’ve been thinking about using sync for that. I worry about ransomware or some unnoticed corruption getting synced, though, so I’ve favored Duplicacy.
Assuming my above thinking is rational, I’m leaning Duplicacy as I mentioned. But here’s the other big question for me: if I delete some of these movies because I don’t want them anymore, I encode a better version, etc., will prune or some other function of Duplicacy allow me to reduce the storage space used or will it keep getting larger and larger, regardless of how much I’ve deleted since the snapshots were taken?
Thanks for helping me understand.
