How do I backup annotations?

Hi I hope you are doing well today.  🙂

I have lots of annotations for my ebooks and I would like to back them up automatically, like i do my other important documents.  But when i move My Digital Editions folder to my SkyDrive folder, then ADE doesn't find it when I open the program to read my ebooks.

So, can you please help me set up ADE to automatically backup my annotations to my SkyDrive.  i am using Windows 8.1

Thank you for your help.  Take care, and have a good day.  🙂  Barbara
