If you encrypt at home it doesn't matter where you do offsite. See Cryptomator for an easy platform agnostic approach. Why trust the bastards?

Ah, should have updooted darntootin, oh well. Still, OP, a bit more detail (like I encrypt with rclone, would have been nice.) Cool. Got my own system, but anything that helps...

How are you handling versioning and deleted files?

It seems like Restic would be a better option? It only backs up changed files and handles versioning, encryption, deduplication, and some fault recovery allready. You wouldn't need all of the other layers like the export script and float.
