All my video media is stored in-house. My music library and pictures are all backed up on a storage box from Hetzner. 5tb for 11 euro per month. I don’t think they scan the files in your storage box, but like I said, all my video media is on drives on my home network.

Encrypt your backups and you are good.

Don’t worry about backing up that stuff, everyone else is already, so in a data loss event you can always get it again from the internet.
