Backup vbscript for VMWare Server: Only ~1min downtime posted: Dec 6, 2007 7:22 PM

I've been working on this script for the last week for my school's admission office. I'm no vbscript expert, but I know enough to get things to work. The script is able to achieve minimal downtime by using Microsoft's volume shadow copy service (the script will work only for Windows XP and Windows Server 2003; it may work for Vista as well, if you can find vshadow.exe for it), which you'll have to download (search vss sdk at http://www.microsoft.com/). This script is and adaptation of a script previously posted in this forum by saxa which can be found here: http://communities.vmware.com/thread/54782. Make sure to read all the comments in the beginning and follow any instructions. I haven't tested very thoroughly, so if you find problems, tell me and I can try to fix them. Enjoy! (The script is attached) Do not just run it; save it then right click edit it to read the comments in notepad.

I can't seem to get the script to run properly. Whenever I run it, I get the following error:

The Backup Script for VMware Server couldn't create an appropriate connection.
Please check if all of the VMWare Services are up and running.
Please keep in mind, you can run this script on the local host only.

I am running VMware 1.04 and have VMware tools installed on my virtual machine.

Any ideas?

Where do I get the copyfiles.bat and callback.bat? Can I create them myself? Also, I keep getting the same error as ktlevy when trying to run the script. The script from the original post works fine.

Thanks.

copyfiles and callback are created by the script and then deleted after it
runs. What arguments are you calling with the script, or are using the
interactive mode (just double clicking it)? The script is failing to
connect to vmware, but I have the exact same code from the original script.
Try commenting the line "On Error Resume Next" from the script (by opening
it with notepad then edit->go to: Line 64 and adding a ' in front of it,
like the other comments above it) and running it again to see if it will
give you a more detailed message. Tell me what it says then.

Ok, I had an error with CDO, so I just commented out all the "mailing" references. Now I am getting a VShadow error. The VM does actually shut down, but never restarts (im guessing because the script errors). The Vshadow error is "The backup script couldn't create a valume shadow or couldn't copy the files from the volume shadow". vshadow.exe is both in my path and the directory I am running the script from. And is enabled for the source drive (Where the VM's are).

Thanks.

Ok, still having CDO mail issues, but I figured out the issue. My VM drive is E: not C:, the script line 657 is hard-coded to C:. Any idea on how to get email working? I checked google and done all the reinstall, and re-registering of dlls already.

Thanks, Great script !!!!!!

Good job debugging, I should have noticed the drive thing when I wrote it.
Anyways, the only problems that I can really think of with the mailing stuff
is maybe you forgot to fill in the smtp variable near the top of the script
(line 72). Whats the specific error you get when you run?

I've updated the script to fix the problem, it now uses the first two letters from the path to the vmx file as the volume shadow drive

I figured out what my problem was. I'm running Windows 2003 R2 Enterprise Edition 64-bit and things were not working properly because the default cscript.exe in c:\windows\system32 was the 64-bit version. Once I made the 32-bit version in c:\windows\syswow64 the default version, the script ran properly. I had also discovered the hardcoded C: issue and changed that to D:

Hi

I'm trying to get this to work, but the Virtual Machine won't shut down. What could be the cause (and are there alternative ways to automaticall shut it off?). We use VMWare Server 1.04 (for as much as that matters)

thanks in advance for any help!

Make sure you have VMTools installed on the Virtual Machine. Also, the suggestion above, to comment out line 64 "On Error Resume Next", will give you a more informative error.

If commenting the on error resume next still gives you an indescript the server cannot be shut down, it might be because there is something running on your vm that is preventing it from being shut down. You can try the script on another vm, if possible, or you can make a test script that only tries to shut down the server to see if thats the problem.

okay, now I get this output:

C:\scripts>cscript.exe vm-vss-backup.vbs "e:\Virtual Machines\PPS_SR_WSUS\Window
s Server 2003 Standard Edition.vmx"
Microsoft (R) Windows Script Host Version 5.6
Copyright (C) Microsoft Corporation 1996-2001. All rights reserved.

The Backup Script for VMware Server couldn't create a volume shadow or couldn't
copy the files from the volume shadow.

I did install the Volume Shadow client, and I added the path %programfiles%\....\release-server directory to the %path% variable And I've placed shadow.exe in the script directory.

try from the command line
vshadow c:(or any drive you want)
to see if it has some problem
you can also try vshadow -q to see if there are any existing volume shadows. If there are some and you dont know what they are, they might have been created and then failed to delete. Then you can do vshadow -da to delete any that exists.
