# Name: backup.ps1
# Usage: {directory}\backup.ps1 or {directory}\backup.ps1 filepath
# Parameter: $filepath: optional, uses the file in that path as the login credentials. ie: host address,
# username, password
# Purpose: Runs the backup function on the appliance and downloads it onto your machine's drive
# in current user's home directory
# Notes: To improve performance, this script uses the curl command if it is installed. The curl command
# must be installed with the SSL option.
# Windows PowerShell 3.0 must be installed to run the script
