For almost all computer users, the most important information you should be backing up is anything that cannot be replaced. Typically this will include any of your personal document files, letters, photos, finance information, pictures, saved games, etc. Microsoft Windows users will find most of this information in their My Documents folder.

Backup strategies

Backup to alternate medium - Backing up your information to an alternate medium, such as a blank CD-R, blank DVD-R, or USB flash drive, is one of the easiest methods to backup your personal information. Copying files to an alternative medium is the absolute bare minimum method of backing up your information.

Store backups online or at another location - If your home or office were to catch fire or someone were to steal your computer and backups everything would be lost. Making backups that you store at a friends house or storing backups online is the absolute best method of protecting your personal information.

Ongoing backup - Having a computer with RAID or running software that makes backups as data changes can help make sure data is protected as it is updated. An ongoing backup is the best solution for sensitive information that is updated frequently. For example, if you were writing a book having a backup that was a week old could result in hours of lost work.
