DVD, other optical media, or
removable media If you store your backup on optical or removable media, you can only recover entire
volumes, not applications or individual files. In addition, backing up to media that has
less than 1 GB of free space is not supported.
Local hard disk If you store your backup on an internal 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.
However, you cannot perform an operating system recovery if the backup is on the
same physical disk as one or more critical volumes.
Also, the local disk you choose is dedicated for storing your scheduled backups and is
not visible in Windows Explorer.
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.
