I have an adblocker and never realised that flickr had any ads. On the downside I find it terribly slow. It's good that it stores full size images, has a lot of free storage, stores exif info and maps the pictures (you may not care about those last few).
Personally, for backing stuff up I use Microsoft onedrive. I pay about £60/year for office and with that you get unlimited online storage. Very good deal if you need office anyway.
Ultimately though, in the first instance I'd back things up to a local drive somewhere. Storage is so cheap that it barely costs anything.
