Again I ask, where should I take ~30GB of photos that I have on Flickr? Yes, I have other backups but I need offsite storage. Guess I'll have to budget for it now. Backblaze B2 isn't quite ready yet.
It depends if you want backup or sharing in the flickr vein. If the latter, Smugmug is probably the closest equivalent. It's not free but neither was a flickr pro account.
Google Drive, Microsoft One Drive, Amazon Cloud Drive, etc. They're all very reasonably priced in my opinion (Amazon's says they give you unlimited). But if you want something more sharing oriented like flikr then that's a different beast. You can kinda do that with Google Drive and Google Plus but no one uses that.
As much as I shudder saying it, Google+ has been pretty good at keeping all of my photos. Though I have them backed up from my Android device. Not sure how well it works when actively using it for photo storage.
He was looking for an off site backup meaning all of his current backups are at a single location. You need redundancy in your offsite backup (or have multiple) otherwise you may have to use it one day and find the drive has died or who knows what else.
