Sample Bourne Shell Scripts
The following sample scripts are provided to assist administrative users in executing
Bourne Shell scripts for agents. You can use the sample scripts and customize them
as needed. The sample scripts for agents include:
 PreTransferScript.sh
 PostTransferScript.sh
PreTransferScript.sh
The PreTransferScript is executed on the agent side prior to transferring a snapshot.
The following script stores the values from input parameters in the
Pre(Post)TransferScriptResult.txt which is located and stored in the root home
directory.
Sample PreTransferScript
#!/bin/bash
echo
"TransferPrescriptParameter_VolumeNames=$TransferPrescriptParameter_Volum
eNames
TransferPrescriptParameter_ShadowCopyType=$TransferPrescriptParameter_Sha
dowCopyType
TransferPrescriptParameter_Key=$TransferPrescriptParameter_Key
public bool IsLogTruncation { get; set; } Gets or sets the value indicating whether logging is
being truncated.
public uint LatestEpochSeenByCore { get; set; } Gets or sets latest epoch value.
The LatestEpochSeenByCore method is the ordinal
number of the most recent snapshot taken by the
Core. This is the 'epoch number' assigned by the
filter driver to this particular snapshot at the
moment it was taken with VSS.
The agent uses the 'exec' shell command to launch the scrip. You can indicate which interpreter
should run the script by defining that information in the first line of the script, which is similar to
what you define for any normal script being executed from the command line. If you don’t specify
the interpreter, the default shell will interpret the script. If you choose something other than the
default shell, you will have to ensure that the specified interpreter is available on all protected
machines.
