50 Using Your NAS System
External hard disk If you store your backup on an external hard disk, 
you can:
• Recover files, folders, applications, and volumes.
• Perform system state and operating system 
recoveries if the backup used contains all the 
critical volumes.
• Easily move backups offsite for disaster 
protection.
If you store your scheduled backups on an 
external hard disk, the disk is dedicated for 
storing your backups and is not visible in 
Windows Explorer. 
This enables users to move disks offsite for 
disaster protection and ensure backup integrity.
