Automating Windows Backups for Workstations
Today I wrote a small Windows command line script for automating
Windows backups on ordinary workstations (My Documents folder, Outlook
PST files and several application directories).
The script runs fully automatic and is therefore very user-friendly because
the technical barrier for making backups on workstations must be as low
as possible, otherwise no backups are made (this is my experience). The script
is also capable of copying files from remote computers to back them up on a
local CD burning device.
So here we go.
I assume that the destination folder for the temporary backup files and the
directory where all the tools needed reside is "C:\Backup
I also assume that you run Windows XP (because of the "rd
" command (older versions of Windows don't have this command,
but you can use deltree instead).
Installation of the tools:
First of all you need some parts of the UnxUtils package
. For this script we only need "tar.exe
". If you want to compress the generated tar file
you will also need either gzip or bzip or some other compression utility.
The reason why I create a tar file to be saved on disc is because of the long
filenames that may occure on Windows systems (more than the ISO9660 standard
The next thing we need is the cdrtools package for Windows
. From this package we need "cdrecord
" and "mkisofs
Discover the CD burning device
To discover the CD burning device for cdrecord, use the following command:
Which produces an output like:
0,0,0 0) 'SEAGATE ' 'ST318453LW ' '0003' Disk
0,1,0 1) *
0,2,0 2) 'TEAC ' 'CD-ROM CD-532S ' '1.0A' Removable CD-ROM
0,3,0 3) *
0,4,0 4) *
0,5,0 5) *
0,6,0 6) *
0,7,0 7) *
In this case, your CD burning device would be "0,2,0
The directory structure:
If you did everything right, you should have a directory structure like this one
12.01.2006 11:57 <DIR> .
12.01.2006 11:57 <DIR> ..
12.01.2006 10:43 1.655 awbfw.cmd
17.05.2005 15:16 314.368 cdrecord.exe
03.07.2005 02:30 1.295.582 cygwin1.dll
17.05.2005 15:16 421.376 mkisofs.exe
11.11.2001 00:00 114.688 tar.exe
Please keep in mind that the synthetic linebreaks (\ at the end of a line, etc.)
are not functional in Windows command line scripts. I just put them in here
so that the Code-Block doesn't get to wide.
