ZBACKUP - Zip Backup Utility
PURPOSE: To backup all filespecs specified in the index file,
C:\ZBACKUP.INX, in PKZIP (by Phil Katz) format to diskette(s) in
drive A:
SYNTAX: ZBACKUP or ZBACKUP ?
REQUIREMENTS: There is enough disk space in the root directory of C:
to hold the file ZBACKUP.ZIP. Index file C:\ZBACKUP.INX must be
present.
RESULTS: The file C:\ZBACKUP.ZIP will be created such that all files
specified in the file C:\ZBACKUP.INX will be compressed to
C:\ZBACKUP.ZIP. The The Backup file will include pathnames.
DETAILED USE: BACKUP, VIEWING CONTENTS, AND RESTORE
The file A:\ZBACKUP.INX is a sample ASCII index file; the index file
can contain any valid DOS filespec including wildcards; it may
contain filespecs from any valid mixture of PC drives.
TO DISPLAY THIS DOCUMENTATION Issue: ZBACKUP ?
TO DO AN ACTUAL BACKUP OF SELECTED FILES Issue:
1) EDIT C:\ZBACKUP.INX and make sure this inclusive list suits
you.
2) ZBACKUP to do actual backup
TO RESTORE Issue:
0) RESTORE B: C: /D this should display the BACKUP contents as the
single
file ZBACKUP.ZIP
1) RESTORE B: C: this puts B:\BACKUP.001, .002, ...back to
C:\ZBACKUP.ZIP
2) MD C:\TEMP
CD C:\TEMP create a subdirectory to hold restored files.
PKUNZIP -d -j C:\ZBACKUP.ZIP filespec
e.g., PKUNZIP -d -j C:\ZBACKUP.ZIP WATFOR77\*.FOR
will restore what might have been C:\WATFOR77\*.FOR to
C:\TEMP\WATFOR77\*.FOR in a safe way, prompting to replace any
filespecs already there.
NOTE: If only one diskette is needed to hold your C:\ZBACKUP.ZIP
file, then the file A:\BACKUP.001 is in fact a Zip file and may be
treated as such. I.e., DOS 5.0 Backup doesn't alter C:\ZBACKUP.ZIP;
so if it fits on one diskette it remains a Zip file under the
fileid, BACKUP.001. Thus in this case Steps 0 and 1 above could be
eliminated and at Step 2 issue instead: PKUNZIP -d -j A:\BACKUP.001
filespec.
TO MAKE A DIRECTORY, ASCII TEXT FILE BACKUP.DIR, OF ALL BACKED UP
FILES Issue:
1) RESTORE B: C:
2) PKUNZIP -V C:\ZBACKUP.ZIP > C:\BACKUP.DIR
TO ADD/UPDATE files to ZBACKUP.ZIP add them to C:\ZBACKUP.INX and
(re)issue:
the command: ZBACKUP
TO GET BRIEF HELP FOR PKZIP ROUTINES Issue:
a) PKUNZIP or PKUNZIP -h
b) PKZIP or PKZIP -h
