Distribute Directory Trees from a Source Server to Multiple Target Servers 

Keywords:   distribute directory trees
The following sample code will distribute directory trees from a source server to multiple target servers, optionally deleting existing target directories before copy. Execution can be deferred for up to 12 hours.

Ideal for copying applications and data around servers during off-peak periods. Activity is logged to a logfile. 

;**************************************************************************
;DISTRIB utility for distributing specified directory trees from a source
;server to a target server. An INI file is used to hold the source and
;target information, as detailed in the Sample Format below.
;Written by Edward Tippelt  ert@pobox.com
;Compiled and tested using Winbatch 98E
;Revision History
;Oct 1998
;1.0    Initial Release
;1.1    Added directory tree size checks to validate copies
;1.2    Added code to blat targets prior to copy if requested
;       Added better delay code around BoxText updates using TimeDiffSecs
;Nov 1998
;1.3    Fixed problem with target directory names containing spaces
;1.4    Replaced call to Deltree with a routine written in Winbatch
;Dec 1998
;1.5    Added feature to defer copy process in 1 hour increments

;SAMPLE FORMAT OF DISTRIB.INI

;[Parameters]

;SourceRoot=\\src_server\apps\released\apps
;Target1=\\targ_server1\apps\released\apps
;Target2=\\targ_server2\apps\released\apps
;Target3=\\targ_server3\apps\released\apps
;Target4=\\targ_server4\apps\released\apps
;Target5=\\targ_server5\apps\released\apps
;Target6=\\targ_server6\apps\released\apps
;Target7=\\targ_server7\apps\released\apps
;Target8=\\targ_server8\apps\released\apps
;Target9=\\targ_server9\apps\released\apps

;The DISTRIB.INI file must be in the same directory as DISTRIB.EXE,
;as that is where the program looks for it.
;DISTRIB.EXE uses the XCOPY32.EXE file to perform the actual copy,
;so this file must be somewhere on the path of your workstation.
;When the program is launched, the subdirectories directly below the 
;SourceRoot folder in the Distrib.INI file are presented in a 
;selection box.
;You can select one or more of the subdirectories shown there, and
;when you press OK, each of the selected subdirectory trees will be
;copied below each of the TARGETx folders listed in Distrib.INI
;An option allows you to delete existing target directories and create
;new ones from scratch to make sure source and target are identical.
;If the subdirectories do not exist, they will be created, including
;empty folders. Existing files will be overwritten, regardless of
;version. (All controlled by switches on the XCOPY command line)
;When each XCOPY32 process is complete, an entry specifying source
;and target folders will be written to DistribLog.txt, in the same
;folder as the executable and INI file, so it cannot be a read-only
;network share. If the program fails at any point, the log file 
;will show how far it got successfully. The DistribLog.txt file 
;is overwritten each time the Distrib.EXE program is run, 
;to avoid building up a huge logfile.

;Source and target locations are referenced by UNC addresses in the
;example above, although conventional drive letter assignments will
;also work. However, it is assumed that the user account under which
;DISTRIB.EXE is being executed, has READ/WRITE access to all the
;specified target folders. Additional target directories can be
;added if required, the only important requirement is that the
;numbering of Target1, Target2, etc, is consecutive. (If a number
;is missed, any target directories with a higher number will be
;omitted)
