calculating space requirements for Exchange 2010

I am running through the calculator worksheet for Exchange 2010 and trying to figure out exactly what I will need.

I have run the analyzer on my current Exchange environment and know the size that is needed for the Exchange databases. However I also see that it is requiring a lot of space for restores.

I will be using NetBackup for Exchange backup. Will I need a seperate recovery LUN in order to perform a recovery for all of the databases on exchange, or can I make it just large enough for one database to be recovered?

>> IMO, yes\no
we just need sufficient spaces for the restore and recover the database.
if this shouldn't affect\impact\load other *operational* databases...then we may need to go for seperate LUNs

and you have to think what LUN you are using, given Exchange 2010 can use SATA or JBOD

 and do you really need to use NETbackup for backup solutions or DAG is sufficient to do the work ?
