I back up my photos to a Synology NAS via USB cable a little more frequently than quarterly. The NAS does off site backups to aws glacier (low price s3).

Anything interesting I download, pdfs etc periodically I'll backup to the NAS before I retire a phone. Anything that's not photos I just assume are destroyed when I upgrade and that's fine I don't keep anything else on my phone.

The NAS for backing up my desktop has been very freeing, dumping my Documents folder to the network and installing a fresh copy of Linux or whatever is very freeing.
