I have mine on a "My passport" external drive, learnt the hard way when I lost a lot of the HQ pictures of a holiday in New Zealand when Laptop died and had to have my hard drive scanned to save everything possible.
if you have a few weeks of spare time go through the ten years of pictures, and delete the ones you don't want,(and i am sure there will be lots, duplicates, blurred, etc etc), then using Windows Picture manager, or a similar programme, edit the important ones, edit the size( in bytes) and email them to yourself to a address on Google, Microsoft etc, this is what I Find to be the safest, let these big companies look after your pictures for free, you could also make a copy to a DVD, and a memory stick to be sure.
I've already done that , i used to use the Tapatalk , but now i use the Google or Gmail to do it , as you say , they are free and safety place to backup phone pictures and other data for user ,if you have a few weeks of spare time go through the ten years of pictures, and delete the ones you don't want,(and i am sure there will be lots, duplicates, blurred, etc etc), then using Windows Picture manager, or a similar programme, edit the important ones, edit the size( in bytes) and email them to yourself to a address on Google, Microsoft etc, this is what I Find to be the safest, let these big companies look after your pictures for free, you could also make a copy to a DVD, and a memory stick to be sure.

An IT Geek friend of mine recommends the rule of three:
1. Back up to CD
2. Back up on an external hard drive (although I did lose a load of music once on a drive that just locked up and stopped working).
3. Back up on an offsite server such as a (reputable) cloud - I did read in Which? magazine that you do have certain rights for loss of data on off site storage and may be worth a search on the web to find the article.
I try to keep all my photos on my PC in the same format and folder storage, that way all I do is drag and drop them across to my external drives and any duplicated can be ignored (when the system asks you what to do).
