i use duplicati to back up configs and data for docker containers to 2 cloud services. my 8 TB server is almost maxed. i need funds to buy a backup for that and expand.
I know synology (and others probably) have an app where you can back up your data to your friends NAS and vice versa, but that’s taking up their storage too and cost for HDD/SSD may be prohibitive
idk how much you know about docker, but that’s how i have everything set up. i use sonarr with prowlarr (indexer) and a torrent downloader. the only thing the isp will care about is downloads so put torrent-dl behind vpn like nord. i use gluetun to do that, but there are other ways too. at the end i use plex because i like the apps ecosystem with music player, but a pass costs like $100 for life. otherwise check out FOSS jellyfin, many users like that.
these apps all have git repos and websites to explain their uses, you’ll be fine with your background. if you haven’t used docker, i recommend it, but its not required for anything, especially on windows
This is where the beauty of sonarr come in
For komga you can and it and enter your komga domain, username and password for access.
I personally use FMD2 to scrape manga chapters
Komga is very stable and about to hit v1.0. it and Kavita have different structure for organization (komga’s being 1 folder is 1 series and kavita’s is some folder and some metadata). Komga is focus on comics and manga and has a great web reader with fantastic integration with tachiyomi and tracking manga/comic progress that sounds to their site and tachiyomi. Kavita has a few features komga does not, such as the ability to read ebooks, send then to Kindle, kobo, and others. They do seem to have more updates but are also still beta now. Both are great but have their strong suits.
Seconded Kavita for an ebook reader. Both it and komga do manga and comics very well, but Komga does not do ebooks
Check out deemix. Self hosted app that can use Spotify playlists and with a free month of premium account you can get FLAC quality
Best advice is not to expose it publicly.
If you need access outside your LAN try using a VPN to your network with wireguard (wg-easy is nice) or tailscale (there are others as well).
If it’s using a domain/subdomain make sure you use secure usernames and passwords, or things like authentik, authelia and the like to buff up security.
