Free Backup Tools for Windows

I recently saw a recommendation for some free backup tools for Windows, and I thought I’d pass them along. The following can be useful in different circumstances, over the regular Windows backup:

For full drive backups:
DriveImage XML Backup Software

For backing up individual files to another drive:
SyncToy from Microsoft

When a hard drive fails, it’s best to be prepared. Your data is a terible thing to waste!
