Keep in mind bitrot is a real thing if you roll your own storage. While most cloud storage solutions store multiple copies of your data I'm not sure if all of them have a system that checks for and fixes bitrot.
I love my ZFS server as it handles all that transparently but that's really not an option for everyone.
I think I have some bitrot in my photo collection, there are a few pictures that seem to be broken, but it's far less than 1%. I'm fine with it. I could probably restore most of those images if I tried.
After I got my server going I transferred all my photos over and ran a utility overnight to check them for corruption, the name escapes me but it was an open source cli program. A small number of images were corrupted and the majority were replaced with thankfully pristine backup copies. The rest were restored with minor visual glitches.
