Staging Location for GRT backup job is set to C:\
I was aware that in order to have single item recovery using GRT a temporary space is required to stage the DB for example for exchange and then from there we can pull individual item. This is case when restoring from a tape.
Today I noticed that in backup exec 2012 under config settings > storage there is staging location also set to C:\ and this is for backup jobs. Before I never noticed this item and now I want to know that does backup exec also requires same huge amount of space when running GRT based backup jobs to tape ?
See attached picture with red outlined portion. Since, it doesn't make sense to me to assign another big partition to Bexec server for GRT backup jobs so for this I need to understand how much space it requires in staging area.
