WD My Book not backing up all files

I have been using my WD My Book for about a year now.  I have it set to constantly back up files.  I went in today to check how it was doing and found that recent files (within the last month) have NOT been backed up in some of the folders.  I can’t seem to figure out why.  Any thoughts?

Hi and welcome to the WD community.

Try to make sure that you are using the latest version of the software. In case you are o the latest version try to disable the backup and re enable the backup again.

Hi,

I just discovered my Passport Essential SE is no longer backing up files.  Any suggestions?
