Okay, just found out that in our particular case "the EBS provider will be the FILESTREAM option of the SQL Server 2008R2".
Following on that, SMSQL 6.0 IAG says:
"Filestreams are fully supported by SnapManager for SQL Server, and filestream objects configured within SQL appear in the SnapManager for SQL Server GUI. If you have a database that includes filestream objects, SnapManager for SQL Server can back up and restore the filestream objects along with the database."
Looks like we are good to go?
