	Useful Tip of the Month Dr. Sheryl Beller-Kenner © June, 1998
	The term is quickly coming to a close. Before you shut down your computer for the last time before the summer vacation, back up your hard drive. When back up? on a regular basis   programs - after changing any preferences (menus, tool bars, etc.)   data files - after making any changes, at end of work session   Ways to back up? on floppy disks (use if you have relatively little on your hard drive; short-term storage - a few months; easy to damage disk) drag files you want onto disk use a back-up program such as CopyDoubler (copy only files that have changedsince last work session); can be done unattended at pre-set times; option for archive (individual file) or disk image (whole disk at once) on tape ( for 2-6 gig; short-term storage - up to a year or so; easy to damage tape)   on a removable drive ( for 100 meg - about 3 gig; long-term storage - up to a few years or so) Optical drive holds 100 meg to 3 gig; fast, small, reliable; difficult to damage disk Iomega drive Zip drives holds 100 meg ;Jaz drive holds 1 gig; not as fast as hard drive Syquest drive holds 44 to 270 meg; not as fast as hard drive   CD-ROM backup up to 600 meg; for permanent information such as applications (can only write once, but multi-session option permits you to add more info at a later time); very long-term storage; easily scratched if not kept in case   Network backup your system administrator can set up remote backups to a networked drive (tape or other type); slowest method, but most reliable and efficient   Why back up? to make sure that all of your programs and data files are safe from summer intruders   to enjoy your vacation, resting assured that your files are safe and secure. Have a great summer! This month's tip was submitted by Dr. Sheryl Beller-Kenner. To submit a tip, please send tip to Dr. Sheryl Beller-Kenner.
