Title
vRanger back up purging the Exchange log files before backup, logs may be inconsistent -
Description
When using a vRanger backup using quiesced snapshots and the vzShadow_x64 or vzShadow_x86 to truncate logs, Exchange logs are purged before the backup starts and may be in an inconsistent state when the backup completes.
-
Cause
The vzShadow executable is called twice during a backup cycle, once when the snapshot is created and once when the snapshot is removed. During the quiesce/unquiesce cycle, VMware tools will run all files in the C:\Program Files\VMware Tools\backupscripts.d directory, passing each file a parameter indicating whether this is a freeze or a thaw cycle. The freeze.bat file as initially provided does not check the parameter so vzShadow is run both times.
-
Resolution
Move your original freeze.bat file into another directory. This is because VMware tools will run ALL scripts in the directory in alphabetical order. We only want to run a single script. Copy and paste the text in the Additional Information box below into a new file. The very first line of the new file should be @echo off. For consistency, we suggest that you call the new file freeze.bat. Open the original freeze.bat file in Notepad. This file will probably have a single line in it. Copy that line and paste it into the new freeze.bat file to replace the sample line immediately after the line that says ":thaw". Save this as the new freeze.bat file and test it with a backup.
