For those who don't need quite as much storage (12tb!) I recommend trying Apple's new iPhoto library. It has been pretty close to a dream solution for me.
Now I can take photos on a trip, upload them via my iPad. Make edits to RAW files, curate, and it syncs every time I can connect to wifi, backing up my originals and syncing across all changes to any Apple device (and web).
Do you backup the library to something outside of iPhoto? I've been wondering if there's a nice automatable way to backup that library onto a home Linux computer.
Yes I also keep my own backups. I use Crashplan for the iphoto library, as well as a local SSD backup.
Fortunately iPhoto libraries are just folders so by backing it up you can always take out the folder of originals and put them in Google or anything else.
