Backing Up Your Computer Files
This chapter includes the following topics: 
About Backing Up Your Computer Files
The WD SmartWare software automatically and continuously backs up all of the content 
(music, movies, photos, documents, e-mail, and other files) on your computer to your My 
Book drive. After the WD SmartWare software categorizes the different types of content 
you own, simply clicking the Run Backup button will back all of them up. Advanced 
users can select specific types of content to back up.
After performing a backup, the WD SmartWare software protects your files by backing 
up any:
•   New file that is created on your computer or copied to your hard drive
•   Existing file that is changed in any way
This protection is automatic—the WD SmartWare software does it for you without any 
action on your part—just make sure to leave your My Book drive connected to your 
computer.
Note: Automatic backup protection is continuous for as long as your My Book 
drive is connected to your computer. Then, whenever you disconnect and 
reconnect the drive to your computer, the WD SmartWare software rescans your 
computer for new or changed files and resumes automatic, continuous backup 
as before.
Additionally, the Backup screen (see Figure 10 on page 15) provides:
•   Content Gauges for your computer’s disk drives, so you can see the number of 
files and the storage size for each content category
•   A Refresh View button for refreshing the Content Gauges
•   A Detailed View content box that you can use to select specific categories of files 
or folders to back up, with an Apply Changes button for implementing your 
selections
•   Run Backup and Pause Backup buttons for starting and stopping backups
