ok really late response on this one.
Is 10d server compatible with ralus 11d?
Backup Exec 10d will not backup a ralus 11d agent, but an Backup Exec 11d will backup a 10d ralus agent. You will just get an exception in the job stating you need to upgrade the remote agent.
As for that table, it is partly incorrect. The last line if I read it correct is wrong. 11d will backup agents from lower versions. As I stated above, you will just get an exception stating the agent needs to be upgraded.
