I don’t know if these are uncommon but I have a few cool usecases besides the regular 1:1 folder syncing, maybe someone else finds them useful.

Also you should know that the way I have all of this setup is that I have a container that hosts a bunch of SMB Network drives and a syncthing container that stores all of the fodlers on that drive. Having them also easily accessible through smb is great when I just wanna quickly copy something or back the folders up.

So here are some of my maybe unorthodoz usecases :

• Music - As a fan of offline music, I have it setup that music I acquire gets synced onto the server and re-encoded as opus through a script into a second folder which then through syncthing gets sent out my mobile devices. There I rather have smaller files than lossless quality. Said script also sorts the music into folders based on artist and album metadata.
• I also sync my Newpipe Subscriptions between phones (unfortunately by manually exporting my settings and re-importing them)

I also used to have a setup that would sync Minecraft Bedrock and Stardew Valley saves between devices (where Windows and Android saves are compatible) but Android 11 introduced a stupid restriction that prevents synching from accessing the the saves are located on Android.

ok that is wild! thanks!

Ok thanks, it then seems like some Software thing. Are your clock speeds also higher under linux when idle?
