What is the best use case for BE15 Windows Agent and its down sides if any ?

Hi All,

I got the following license for the BE15 agenst:

SYMC BACKUP EXEC 15 AGENT FOR WINDOWS WIN PER SERVER BNDL STD LIC EXPRESS BAND S ESSENTIAL

I'm trying to make a good use of the existing licenses that I've got to protect my physical windows server, but not sure what are the downsides without the specific paid license for the agents like AD, SQL, Exchange, SharePoint agents.

is there any pros and cons when using this type of agent backup to the tape ?

Any idea and suggestion of what is the good use case or example would be greatly appreciated.

Thanks,
