There are several "cloud" storage sites. Meaning you can save everything off site on a secure server.
I do that as triple protection in case anything ever happened to my house and I lost everything.
We (wife and I) have our PC, laptop, and two smartphones update daily to Just Cloud. We can then access any of the files from any computer, tablet or phone anywhere we are. Also, they store all files, not just pictures.
There is an annual cost but we have just too many family pics to risk ever losing.
Do a Google search for online storage and see if it's something you are looking for.
