PowerShell automation for off host backups using a Volume Snapshot.

# The following directions show you how to create an encrypted xml file that

# contains the username and encrypted password. You populate a variable then use the variable in the

# command

# Use this command below to export encrypted credentials to file...It will prompt for your Equallogic

# username and password.

# Then change the file name above in $CredPath to the new path\file...etc.

# $MyCredentials=GET-CREDENTIAL –Credential “Username” | EXPORT-CLIXML C:\eqsnap\cred.xml

# Then use the following command to poplate the variable $Credentials with the username and

# password;

# $credentials = Import-CliXml -Path $credPath

# $credentials will be used in the Connect-EQLGroup command below

# Please Note: I did this to prevent users who have access to the credential file from seeing my clear text

#password.

# However, This doesn't prevent someone from decrypting the file who knows what they are doing so

# please lock down access to the file.
