I would like to keep a remote repo of my most important files, which I cannot re-create by any other means.
As such, I would like to snapshot a directory, maybe
/important, which changes. For example, write some files to that directory, take a snapshot, delete the files, and add new content, take new snapshot.
I would like the current snapshot to include both sets of files somehow, rather than snapshot 1 having the original stuff, and snapshot 2 missing those files.
Is this possible? Through some kind of clever scripting or union mounting or some such solution?
