exchange backup with Data Protector 7. Need some advise

Hi,

We have Data Protector 7 and Exchange 2010. I installed DP7 client to exchange server. In DP7 I configured "MS Exchange 2010 Server" backup withsoftware providers and started backup. It is strange as I see that DP7 is backing up "/Microsoft Exchange Writer(Exchange Information Store/1sd51sds-45sd-d4ghj5d4f-df48-dfrgferr54fd/File)".

I mean that I see Exchange Information Store ID, is it correct?
How to know which DATASTORE I am backing up?
Shuld I use software or hardware providers, as exchange is virtual machine?

thank you,
