FORMAT
The format of the Diskpack command is
[d:][path]DISKPACK [d:][path]filename[.ext] d: [options]
where
[d:][path]
before DISKPACK specifies the drive and path that
contains the Diskpack program.
[d:][path]
after DISKPACK specifies the drive and path that contain
the file(s) you want to back up (source).
filename[.ext]
specifies the file(s) you want to back up. Global file
name characters are allowed in the file name, and cause
all of the files matching the file name to be backed up.
d:
specifies the drive that will contain the backed up files
(target).
[options]
specifies optional parameters described below.
OPTIONS
The following options can appear in the Diskpack command.
/?
Display help.
/1
Do not prompt to insert the first backup disk.
/A
Do not change the archive bit of each file copied.
Without this option, Diskpack clears the archive bit of
each file it backs up. When cleared, the archive bit
indicates that a file has not been changed since it was
backed up. Whenever DOS writes to a file, it sets the
archive bit to mark it as changed. Normally, you should
omit this option so that /M can be used to back up files
that have been modified since the last backup.
/B
Beep when prompted to insert a disk.
/C[[d:][path]filename[.ext]]
Create a catalog file containing a list of all the files
backed up. You can specify the name of the catalog file
(and a drive and path). If you don't, the file
DISKPACK.CAT will be created in the current directory.
You cannot put the catalog file on the backup disk.
The catalog file is a DOS text file and can be viewed
using a text editor or displayed on the screen with the
DOS TYPE command.
type diskpack.cat
/Dmm-dd-yy
Back up files that have been modified on or after the
specified date. The format of the date specified must be
mm-dd-yy.
/H
Include hidden files. This will cause all files marked as
hidden to be included on the backup disks. If you're
backing up the root directory, the DOS hidden files
IBMBIO.COM and IBMDOS.COM will be copied. You can
avoid restoring these files to a system using a different
version of DOS with the dRestore /P1 option.
/I
Display registration information (unregistered version
only).
/M
Back up files that have been modified since the last
backup. A file has been modified if its archive bit is set
(see option /A).
/P
Display a (y/n)? prompt before copying each file. You
can choose to back up the file or not.
/S
Back up subdirectory files in addition to the files in the
specified or current directory.
/V
Display a verbose description of the back up process.
/W
Prompt the user to press a key before reading source
file(s).
NOTES
ⁿ Press Ctrl-Break to stop Diskpack.
ⁿ New disks must be formatted with the DOS FORMAT
command.
ⁿ You can't back up to a hard disk.
ⁿ Files are backed up from the current directory if you do
not specify a path.
ⁿ Files are compressed as they are copied.
ⁿ You can't use the DIR command on backup disks. To get
a list of files, display the catalog file or use the dRestore
/D option.
ⁿ You can't use the COPY command to copy files contained
on backup disks.
ⁿ Use high quality disks.
ⁿ Do not use disks with bad sectors as backup disks.
Diskpack will check the File Allocation Table of each disk
and reject those that have clusters marked as bad.
ⁿ Diskpack erases files already present on the backup disks.
