A simple way to reduce the pain of inevitable hardware computer failure is to implement an intelligent and thoughtful backup program. One of the simplest and most comprehensive backup programs available is ADSM, which is now available from Yale's Information Technology Services. Just leave your computer running when you leave the office, and ADSM will automatically start and backup your files. When you need to, you can recover a file, a directory or an entire hard disk. If you delete a file, ADSM will keep a copy of the file available for many days in case you change your mind.
