Excellent, thanks!

No. Rsync works fine, and it is easily testable (untested backups are no backups)

Rsync script that does deltas per day using hardlinks. Found on the Arch wiki. Works like a charm.

I moved to Emby, then to Jellyfin. Also, the other thing that bothered me was that with Plex I noticed I had an online account where I could access all my files. In other words, Plex was using my local data, which was the straw.

I stopped using Plex when I needed an online account to access my local instance.

I just don’t bother with all the categorizing and tagging. I just dump the files in a per album folder and that’s enough for me to find what I need.

I use Kanboard.

I’m self-hosting my mail server for all kinds of neat tricks, like turning mailing lists into RSS feeds and putting attached bills in the right folder. But it is tricky to pull off, because 90% of all email is spam so you must take that seriously because otherwise nobody will accept you mail. One thing I learned quickly is not to use PGP. They almost always and up in spam boxes.

I switched from radicale to baikal because vdirsyncer (which I then used) didn’t agree with radicale on the caldav standard. And I’m very happy with Filestash. It’s fast and does the only thing I need it do do, stash files.

BTW I used to use NextCloud, but that was way too much work and I really like tools that do just one thing and do it well.

Mail server, pi-hole, mediawiki, kanboard, Tiny Tiny RSS, Baïkal, Minetest, Transmission, Jellyfin, Filestash and some homebrew.

I use Wireguard to access all that from outside my network. This way, my mail server only exposes smtp.
