Windows' Backup and Restore feature takes the effort out of performing regular backups. Its default selection automatically chooses your libraries files, which contain your documents, pictures, videos and music. It also creates a system image so you can back up your Windows system files, programs and program configurations. The integrated scheduler lets you decide when to perform backups, so after setting it up the first time you don't have to worry about it again.
Attach your external hard drive to your computer and turn on the device, if necessary. Most external hard drives connect via your computer's USB port, but some drives may use another connection protocol, such as eSATA. The external hard drive should be large enough to accommodate the backup. Microsoft recommends using a hard drive with at least 200GB of free space on it.
