#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
