The example uses local user name and password authentication because the vSphere Automation API endpoint is not yet running when you restore the appliance. The client must connect to port 5480 for this operation.

This example depends on certain variables that specify the source and destination for the restore operation. For simplicity, the variables are hard-coded at the start of the bash script.

This example assumes the backup image is not encrypted.

FTP_ADDRESS=storage_server
