Clustered Microsoft Windows Computer Failover Cluster

I have several servers showing in the servers list of Backup Exec 2012 that are Microsoft Clustered Services/Applications

Like I have been backing up the indivudal nodes

SQL1A - Resources: C drive, utility parition, shadow copy

SQL1B - Resources: C drive, utility parition, shadow copy

But It always list servers by the name of:

SQL1C - Resources: ?\Volume{c1c0805b---------} with the folders Cluster and System Volume Information   with it being only 16 MB
SQL1FTP 
SQL1WEB

How should I back up these non physical computers and if anything would to happen (I'm not sure exactly what), how would I restore them? These are non virtual machines, this is just Failover Cluster
