Daily backups. Currently using restic on my NixOS servers. To avoid data corruption, I make a zfs snapshot at 2am, and after that restic does a backup of my mutable data dirs both to my local Nas and CloudFlare r3. The Nas backup folder is synced to backblaze nightly as well for a more cold store.
I’ve been using logseq with syncthing for sync, across laptop/desktop/Android. Works ok, app can be a little chunky though and sometimes the manualness of coding queries can. E annoying. I have used joplin, trillium, Zim and a few others in the past. Installed silver bullet as a try too but haven’t gotten far into playing with it
My current distro is NixOS - mainly as I’ve built my NAS/homelab. Definitely not recommended for a new player to Linux!
If we had ircv3 specs that included reactions. etc we might be. I rolled a small group of IRC servers with a few selfhost people a year back and it was quite fun. Tbh IRC itself is still alive and well, it’s just not user friendly enough to get non-tech people over easily
