Android internal storage backup with Termux (and ssh daemon and rsync):

and apps I use the internal Google mechanism.

Restic also works pretty well through termux. I found it easier to setup with include & exclude lists than rsync.

Really interesting! Though what do you back up? Just files?

I use root and back up specific appdata and files to a remote backup. I tried backing up the-whole-damn-thing, but it is slow and pointless, hence the picking and choosing.
