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.
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.
