WINCHESTER SUPPLEMENT
Backing up the Winchester Disk
Because it is possible to store the equivalent of several dozen
floppy disks on the Winchester disk, two commands, BACKUP
and RESTORE have been added to the Z-DOS and CP/M-85
operating systems to aid you in backing up your Winchester
Z-DOS partitions. You may elect to copy only certain files,
files updated recently, or the entire partition. The basic opera-
tion of BACKUP is to create a directory of the specified files
and then copy them to a "single" file. The "single" file may
actually be several files that each contain a sequentially num-
bered extension
such as BACKFILE.OOO, BACKFILE.001, and
so on. The system backs up your
fi
les "end to
end" to save
floppy disk space.
The operation is further enhanced by providing an automatic
FORMAT procedure for the floppy disks, protection against
unwanted "overwriting" of existing files on the Winchester,
verification, and so on. For complete details of the features
and operation of BACKUP and RESTORE, refer to your
Z-DOS or CP/M-85 software documentation for the Winches-
ter disk.
Z-DOS
In this supplement, you will learn just one of several methods
of backup for your Z-DOS partition. To backup the entire
Z-DOS partition use the following instructions.
Have a good supply of 5-1/4" or 8" disks on hand that
may be used for backups.
Boot the Winchester system and at the Z-DOS prompt,
type:
BACKUP E: ". ~ A:BACK1 /F/V
