Shadow 2 ($30) from NewTech Infosystems Inc., or NTI can also copy selected directories of your PC as soon as they are created, functionally mirroring them onto an external device such as a hard drive, USB key or even an MP3 player like the iPod. Conventional backup software copies data only once a day or once a week, so the backup is rarely up to date with newer, and often the most essential, files.Shadow 2 also makes it easier to restore your data. Other backup programs store layers of incremental backups in a proprietary format that only they can unlock and recreate. Shadow 2 preserves data in the original format, simplifying and speeding the process of copying your data back.
Through Dec. 31, Shadow 2 software is being sold for 99 cents, making it both inexpensive and easy to make data backup one of your New Year's resolutions.
