Viewing and setting job and server options

# Sample script to gather and set Double-Take job and server options

# You may want to run these cmdlets from the PowerShell command prompt

# so that you can see the values returned for each of the get cmdlets

# and then determine appropriate desired values for each option

# Import the Double-Take PowerShell module

# This may be \Service\ or \Console\ depending on your installation

import-module "C:\Program Files\Vision Solutions\Double-Take\Console\DoubleTake.PowerShell.dll"

# Login to a server by creating source and target objects

$DtSource = New-DtServer -Name alpha -UserName domain\administrator -Password password

$DtTarget = New-DtServer -Name beta -UserName domain\administrator -Password password

# Gather and display several job and server settings
