- The math does not work well here, either. For example, up until a couple
- of months ago I was doing floppy backups on one system that required
- 75 diskettes for a full backup. Anyone above the level of fool should
- keep at least 3 full backups - umm, thats 225 diskettes!!! At a buck
- each, that's $225. I bought a Colorado DJ-10 for $200 (with one
- cartridge). Two additional cartridges were $40 (together, including
- tax). So it is now $225 vs $240, and we have not counted the cost
- of interim backups yet. Then we take into account my time. A full
- floppy backup took 45 minutes of my undivided attention. The tape
- backup takes 15 minutes, but I can do it 'unattended'.
-
- Yes, floppies are an easy out. But anyone running any disk over 100 Mb
- really should invest in a tape drive. The hassles of dealing with
- hundreds of floppies just make if false economy.
-
- (and for folks with multiple systems, just get one of the tape drives
- that runs off the parallel port - backup multiple systems at the cost
- of a single tape drive).
