I never do more than 15 minutes of data entry in Lotus or a word processor without saving the file. I sometimes keep sequentially numbered intermediate backup files to keep track of the changes I've made to a file. For example, I might have the following backup files for a Lotus spreadsheet I'm working on: FILE1.WK1, FILE2.WK1, FILE3.WK1, and FILE4.WK1 (the last being the most current).
Then when I know the final file is perfect, I save it, back it up, and get rid of the intermediate files.
