I haven't used the same phone for 7 years. The value add is that its automatic and remotely archived. I've already been burned by lost / wiped / bricked devices without recovering all the photos / video / data on it before it became inoperable. I still have an iphone 3gs with my last photos with my late grandmother on it that I've tried to frankenstein back to life long enough over a usb connection to just grab the photos with no success.

I've tried a lot of automatic backup solutions like syncthing but have had myriad performance or inconsistency problems over the years.

Its tied to my Google account rather than the physical device, and its not data I need to manually somehow keep consistent across devices because Google does it for me.
