SyncBack 2.1......is a really nifty tool for those who want to keep backups of important data....and do it automatically, schedules and all.
Works a treat, and is well priced [free]....

back when my Computer was a Packard Bell P-200 with a 2.5gig hard drive. Now that I have two 100gig hard drives, I use DI2002 for back up.
