Two precautions - in addition to keeping backups:

1) Mathematica, by default, saves material in an short form to reduce disk
space needed. To use the longer and more secure method (which does not
reduce box structures to linear form) enter the following

SetOptions[$FrontEnd, PrivateNotebookOptions -> {"ShortBoxForm" -> False}]

The change can also be made via the Option Inspector.

2) The utility "Flashback" (Aladdin Systems ) guards against loss due to
corruption and deletion.
