This is somehow related with (part of) this other issue, but I’ll open a new thread to keep things focused.
I’m trying to figure out Duplicacy’s versioning/retention settings (and their limitations). So it is clear that I can set all kinds of sophisticated configurations such as
duplicacy prune -keep 0:360 -keep 30:180 -keep 7:30 -keep 1:7
which will 1 snapshot per day for snapshots older than 7 days, 1 snapshot every 7 days for snapshots older than 30 days, etc
So the retention works at the snapshot level. One important setting for me is, however, to never remove any deleted files (in other words: there should always be at least one version of every file ever backed up). This is not possible with duplicacy, right?
Could it be implemented at all?
