For photos, i have…
Google Photos/Drive. Same thing but for images I use the Photos front end rather than drive. Pay whatever the small amount is for a 200Gb Drive (mix of photos and some other stuff). If/when I fill that I’ll probably just pay for the next level up.
Flickr Pro. Moved up from free when they were absorbed by SmugMug. Don’t really need two cloud backups I guess (as a hobbyist) but I had loads of stuff on Flickr already and prefer it’s organisation and ability to hotlink over Google Photos.
External HD. Photos get backed up to this every so often (basically when I remember).
Local copies on laptop. Basically temp storage. Get deleted once backed up to external HD.
I do have Prime, so could always use their image storage instead, but feels like a hassle to move everything over…
