Is anyone working on a good backup command-line tool? At minimum it should store my own posts. It should also fetch images.

Finally I'd like it to somewhat intelligently fetch conversations. E.g. if I replied, get all posts up to the root. But then ideally fetch a bit more.

It should work incrementally: every time I run the command it never deletes anything, but does add new stuff it finds.

Oh and many store a list of all npubs:

1. That I follow (and follow me) as of the latest backup

2. That I ever followed (or followed me)

Then I run that as a cron job and sleep much better.
