Enlarge Disk storage for BackupExec 2012

Enlarge it to what?  From the screenprint, is Backup Exec showing 2 drives when it's actually one drive split into 2 partitions?  Do you want to combine them into 1 drive?

If that's the case, you'd have to go onto the server and use Disk Manager to remove the extra drive (it should show as a separate partition), making sure you backup anything that's on there, then expand the existing drive to consume this newly allocated 'free' space.

Local Disk D: have free size of 3.42 TB, and only 1.54 TB is allocated for backup storage.

I want to increase it from 1.54TB to 2TB. Is it possible ?

Is Local Disk D your operating system partition?  If not that will make things a lot easier.

Open Disk Management GUI
From Control Panel or from command line (diskmgmt.msc)

You can use the Disk Manager GUI, or if you get an error you can use the command line functions to shrink a Basic Volume.
Then allocate that empty space to the Storage drive by selecting the existing drive and the newly created empty space.

Just remember to run the cmd window as an administrator.

Tks. Can I put all backup under a specifc folder say d:\ExchangeBackup
