I recently considered cloud backup for my photos; could easily have paid for 2TB of Google Drive however Google's reputation in the past couple of years has really nosedived (in my eyes). I don't trust them anymore, they'll just eff up most things I like - eventually.

So went with the Norwegian Jottacloud. Looks quite good, performs well even from down under - uploaded 1.1TB in just a few days.

I have a lot of RAW images; their photo browser displays them fine, however they could do well to update the navigation a bit as it is cumbersome to jump say 15 years back in time.

Edit: It's still amazing to see my collection of NEFs and phone dumps (I clean our phones once or twice a year by moving all photos to the NAS) organised by time, extracted from the dark depths of my NAS drive folder hierarchies.
