PKZIP BACKUP GUIDE
PKZIP can now create .ZIP files that exceed the size of a floppy disk.
You can use PKZIP to backup your entire hard disk and unlike most backup
programs, PKZIP can use disks formatted by DOS, or it can format the disk
for you. PKZIP can optionally erase all files on the destination disk(s),
or leave those files intact. PKZIP can optionally quick format the
destination disk(s), or do a normal (unconditional) format. A quick
format erases the information on the disk without formatting each track,
greatly reducing the time required to format a disk.
Option Description
--------------------------------------------------------------------
-& Span disks if necessary.
You must specify this option if you wish to create a .ZIP file on multiple
disks. If this option is not specified and you exceed the capacity of a
floppy disk, a DISK FULL error message will result.
-&f Format the destination disk.
PKZIP will format the destination disk(s) if you specify this option. If
the disk has been formatted previously, a quick format will be performed,
otherwise a full format will be performed.
-&fl The destination disk is to be formatted to low density.
If you plan to use low density disks in a high density disk drive, this
option is required. For example, if you have a 1.44 meg floppy disk
drive, and plan to zip to 720K disks and your disks are not formatted, you
must specify this option. If your disk drive is a 360K or 720K drive,
this option is not required. If any information was previously contained
on the disk, it will be erased.
-&u Unconditionally (always) format the disk.
Always format the disk before being used. A full format will be used, a
quick format will never be performed. If any information was previously
contained on the disk, it will be erased.
-&ul Unconditionally (always) format a low density disk in a high
density disk drive.
Always format the disk before being used. A full format will be used, a
quick format will never be performed. If any information was previously
contained on the disk, it will be erased.
-&w Wipe the disk. (Erase all files and subdirectories)
This is similar to -&f, except the files are deleted, rather than
formatting the disk. This is for usage with non floppy removable devices,
such as Bernoulli boxes.
-&s[d:] Include subdirectories in zipping process (similar to -rp \*.*).
This option tells PKZIP that you wish to backup the entire disk drive.
The current disk drive will be used if no disk drive is specifed. You do
not need to specify the -rp option (recurse and store pathnames). If you
also specify files on another disk drive, these files will be compressed,
as well as all files on the default drive. (Please see following
examples.)
All options are case insensitive, but this may change in future versions.
We suggest you USE LOWER CASE LETTERS FOR FUTURE COMPATIBILITY. The -&l
option must be specified with -&u or -&f.
Note: If you create a .ZIP file with the same name as exists on a disk
set, you do not need to use the WIPE or FORMAT options. PKZIP will
create a new .ZIP file with the same name; this method is faster.
Note: All the PKZIP Configuration File options can be overridden on the
command line by specifying the option and a '-'. For example,
-&f- will override BACKUP=FORMAT in the Configuration File and
turn off formatting.
Examples
Command Line Description
-----------------------------------------------------------------
pkzip a:zipfile -& Zip the current directory to drive A:, and
span disks if necessary. The files
currently on drive A: will not be affected.
C:\>pkzip a:zipfile -&s Zip all files on drive C: to the A: drive.
C:\>pkzip b:zipfile -&s d:\sd\*.* Zip all files on drive C:
(the current drive), and all files
in the D:\SD directory to the B: drive.
C:\>pkzip a:zipfile -&s d:\*.BAT Zip all the files on drive C: and
all .BAT files on drive D: to the
A: drive.
pkzip a:zipfile -&f -rp Zip the current directory and its subdirectories
to drive A:, and format each disk. A quick
format will be performed if possible, which is
much faster than a unconditional format.
pkzip a:zipfile -&u -rp Same as above, except the disk will be
unconditionally formatted.
pkzip a:zipfile -&fl Zip the current directory to drive A:, and
format each disk to low density. This option
only applies to users using a 360K floppy disk
in a 1.2 meg drive, or users using a 720K floppy
disk in a 1.44 meg drive. A quick format will
be performed if possible, which is much faster
than a unconditional format.
pkzip a:zipfile -&ul Same as above, except the disk will be
unconditionally formatted (do not quick format).
pkzip a:zipfile -&w -rp Zip the current directory and its subdirectories
to drive A:, and wipe each disk. All files and
subdirectories will be erased from the A: drive.
The disk will not be formatted or quick
formatted.
pkzip a:zipfile -&fs Zip the current disk drive (including
subdirectories) to drive A:, and format each
disk. If the destination disk has previously
been formatted, a quick format will be
performed. Otherwise, an unconditional format
will be performed.
New Options For the PKZIP.CFG Configuration File
The keyword BACKUP= can be followed by the following keywords:
SPAN The -& option is enabled. If this keyword is not
specified, the following options will only be enabled
when -& is specified on the command line. Same as -&.
UNCONDITIONAL Format the disk unconditionally. Same as -&u.
LOW Using low density disks. Same as -&l
FORMAT Format the disks. Same as -&f.
WIPE Wipe the disks. Same as -&w.
FULL Do a full backup. Same as -&s.
Examples Same as
--------------------------------------------------------
BACKUP=SPAN FORMAT -&f
BACKUP=SPAN FORMAT UNCONDITIONAL -&u
BACKUP=LOW SPAN -&l
BACKUP=FORMAT WIPE Illegal -- WIPE and FORMAT are exclusive.
BACKUP=FULL -&s
BACKUP=FULL WIPE -&sw
