Tips to crash-proof your genealogy.
You've spent hours inputting 500 years of family history, only to
one day see the “blue screen of death” on your PC. and (horrors!) it's
all gone. Don't take chances with your digital family trees. Follow
these tips to crash-proof your work:
1. Back up your family tree file every time you add
information or make a change. Make a copy on floppy disk, ZIP disk, CD
or other external media. 
2. Periodically make an extra backup and store it someplace
else — in a safety-deposit box, at a relative's or fellow researcher's
house — just in case.
