Choosing Volumes To Backup
To create a backup, you need to specify the volumes that you want to include. The volumes you select impact what you
can recover. You have the following volume and recovery options.
Volume Options Recovery Options
Full server (all volumes) Back up all volumes if you want to be able to recover the full server—all the files,
data, applications, and the system state.
Critical volumes Back up just critical volumes (volumes containing operating system files) if you only
want to be able to recover the operating system or system state.
Non-critical volumes Back up just individual volumes if you only want to be able to recover files,
applications, or data from that volume.
Choosing A Storage Location
To store the backups that you create, you need to specify a location. Depending on the type of storage you specify, you
should be aware of the following issues.
Storage Type Details
Shared Folder If you store your backup in a remote shared folder, your backup is overwritten each
time you create a new backup. Do not choose this option if you want to store a series of
backups.
If the backup process fails while you are trying to create a backup to a shared folder
that already contains a backup, you might be left without any backups. To work around
this, you can create subfolders in the shared folder to store your backups.
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.
