1) Is there any way in the Lite version to copy the data from a S/W raid volume? In other words if we wanted to take a quarterly backup of the data on to a USB drive or something.
You can use the Trial version with the Data Replication.
2) If we take a backup of the configuration and attempt to restore it to an older version of DSS will it work or will that version need to be upgraded first?
For the Settings yes but if the config is different on the other server it will not be the same.
