How to Automatically Backup/Synchronize files with an External Drive
Many people these days buy external hard drives to backup to, but few have a good system in place to automatically backup and synchronize files with the backup drive.
Microsoft has a great, free tool called SyncToy that automates this, so you can practically set-it-and-forget-it.
This tool runs on Windows 7, Windows Vista, and Windows XP. Download it from Microsoft’s web site.
