WD Powerbackup does not restore all files

Hi all,

Having issues restoring a backup that I created with the software that was included on my WD Passport drive. The program runs for quite a while and then I get this error message.

The software version and backup file directory structure is also shown. There are a total of 86 files in this directory

Can I recover the files that give me this error?
Is there any way to see what is in each of these files?
Any help would be greatly appreciated
