With stuff, I mean photos taken with iPhones, random documents, a place to put pre-iOS photos.
Access pattern would be more for trips down memory lane rather than automatic restoration.
Preferably I'd like some cloud syncing thing that also supports syncing to a physical drive every once in a while.
Currently my stuff is all spread out between iCloud, Flickr, dropbox and god knows where.
I'm happy to pay reasonable for it.
Any advice?
It is $9/month/machine these days for unlimited personal backup. Throw everything on to a drive on your machine, make a local copy of that from time to time, and backblaze in case of local disaster, and you should be good to go.
