Granular recovery technology restore staging location

[keyur_desai1]

Hi,

I have configured GRT for Exchange Backup. Exchange version - 2013. Backup Exec server 15 hosted on Windows 2012 R2 Standard 64-bit.

The backup device is VTL. When I run a restore of individual items, it does temporary staging of the entire databse which contains this item which is fine.

The original database size is around 300 GB. However, the staging is already more 430 GB. It seems like the space taken to stage a database is much higher than the size of the database. In GRT best practices document, it recommends database space which is around 1 GB more for GRT processing. However, we are way beyond that now. Can anyone suggest an approximate way to caluculate this staging space?

Are you restoring a DB or a VM? Or a DB on a VM?

You'd need the same amount of storage free as your DB is big. and this stages to C:\Temp by default.
