Backup And Restore in Windows 7 supports backing updata 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 onlychanged 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 purchasethan 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 drivesand 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 likelythat 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 andan administrator backs up the file server. You cansave 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 harddrives
and quickly fill up if you needed to keep copies ofolder 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 easyto carry. They are also easy to lose.
