You have a computer that runs Windows 7.

You need to configure system image backups to meet the following requirements:

* Automatically create a system image every day without user intervention.
* Retain multiple copies of the system image.

Which type of backup destination should you use?

A.
External hard disk drive

B.
Network location

C.
USB flash drive

D.
Writeable DVD

Explanation:
Backup And Restore in Windows 7 supports backing up data files to CD-ROM, DVD-ROM, hard disk (including VHD files), or a network location. You can use Backup And Restore to write a System Image backup to an internal hard disk drive, an external hard disk drive (if formatted with the NTFS file system) and a network location. You cannot use Backup And Restore to write a System Image backup to a USB flash drive, a writable DVD, or a tape drive.

You need to schedule client computers that store important data for automatic backup. After you first configure automatic file backup using the Backup And Restore console, Windows 7 regularly backs up your files. The first time a backup is performed, a full backup is done, including all important user documents.
Subsequent backups are incremental, backing up only changed files. Older backups are discarded if the disk begins to run out of space.

Scheduling Backups with the Backup And Restore Console
Windows 7 Backup uses shadow copies to take a snapshot of your files, allowing the backup to completely back up files even if they are open. Backups are configured and scheduled by using the Backup And Restore console under System And Security in Control Panel.

You can select the following types of backup destination:

An external hard drive
External hard drives are more expensive to purchase than internal hard drives, although you need to balance this against the cost of fitting the internal drive. They can be removed and stored in a secure location. However, they are typically slower than internal hard drives and tend to be less reliable, mainly because they are by default formatted using FAT rather than NTFS. You cannot use an external hard drive for a System Image backup unless you convert its filing system to NTFS. Because it is easily removable, it is more likely that an external hard drive will be missing when a scheduled backup is required.

Network location
If your computer is short of disk space, you can back it up to a network location on another computer or network storage. Note that this is not the same as the situation in a production environment, where users Documents libraries are stored on a file server and an administrator backs up the file server. You can save your backups on a network location only on computers running Windows 7 Professional, Windows 7 Ultimate, and Windows 7 Enterprise, and you need to provide credentials so that Windows Backup can access the network. Bear in mind that you can save your backups on a network location only on computers running Windows 7 Professional, Windows 7 Ultimate, and Windows 7 Enterprise.

USB flash drives
Flash drive memory is considerably less expensive and flash drive devices support much more memory than they did three or even two years ago. Nevertheless, they typically support a lot less memory than hard drives and quickly fill up if you needed to keep copies of older backups. You cannot save System Image backups to flash memory. A flash drive must be able to hold more than 1 GB if you want to save a backup on it. Flash drives can be stored offsite and are small and easy to carry. They are also easy to lose.
