PureDisk

i am new to puredisk. i created puredisk in NBU successfully. Then I created a policy and ran the b/up against the puredisk and got the status code 0(successfull). when i go to the puredisk I see so many folders in it like data, database,etc,history,log,processed,queue,spool,temp,var.

                                          Where is my data that I backed up?
