1. Create a new library, call it "Backup".
1.1. It can be called whatever you want, but I suggest "Backup".
1.2. For these steps, it presumes "Backup".
2. Add the folders you want to the "Backup" library.
2.1. The files will still be in the original location.
3. Make sure the "Backup" library is in your backup profile (meaning in whatever program you use to backup).
If you remove a folder from the Backup library, it will no longer be backed up. Any new folder you add the the "Backup" library, even if it’s outside your user profile, will automatically be included in the next backup.
VALID FOR WINDOWS 7 AND 8.
