When you back up your hard disk using BACKUP, the first
thing to do is to format enough blank disks to hold the backed
up files. Once you start the BACKUP routine, you won’t want
to stop the program to format more diskettes. BACKUP takes
time, even on a high speed computer. Stopping the BACKUP
command before completion usually means that you would
have to start the process over again. Therefore, make sure you
have enough formatted diskettes before you start.
How Many Diskettes?
The number of diskettes you will need depends on two things.
First, how much of the hard disk will you be backing up?
Second, what is the capacity of the diskettes you will be using?
The following table shows the approximate number of diskettes
needed to backup an entire hard disk.

A few extra diskettes have been included in these numbers to
make sure there are enough. If your hard disk is not loaded to
capacity, or if you are only backing up part of your hard disk,
fewer diskettes will be needed.
As you format these disks, prepare labels for them that
identifies these diskettes as a hard disk backup archive. Also
put the date on each label and number each diskette. This is
very important, since the RESTORE command requires that
you use the diskettes in the same order that was used during
the BACKUP procedure.
