how many diskettes would you need to do a daily back up of the file {2 mb total)

The capacity of 3,5´´ diskettes is 1,44 mb. So backing up a file of 2
mb will require two diskettes for one backup copy.

Note too the demand for a daily backup.  It wouldn't be good practice
to overwrite your only backup with a new backup which does not
restore!

If the file is really important, it might be a good idea to use ten
diskettes (or five if the zip works) - a Monday backup, a Tuesday
backup, a ... Friday backup.  If you work seven days a week, amanda,
make that fourteen diskettes (or seven zipped).

And if the file is really really really important, you may want to
archive a copy once a week.

ALSO - it is worth doing an occasional check on another computer, just
to make sure you can restore your backup...

Well, its better to go for Compact Disk (CD) rather than opting for
Floppy disks, as the chances of FDs getting corrupted are higher. Also
using CDs will be a much better and cheaper option, in which the backu
ups could be stored on a daily, weekly, or monthly basis.
