By default yes, why would you think it would be anything else.
There are two ways i can think of that will change this - I will let you do some research to find out what they are, I will however give you some clues.

One way would affect all restores done by a media server and cause all of the restores to by 'run' by one other media server. This setting would be made in the bp.conf file, but can also be ser in the GUI.

The other way changes the media server entry for the fragment in the header file (image catalog). It can be made by running a command, and one of the 'options' you pass to this command is -oldserver.

So below statement is true for all NBU versions?

Restore is done from the same media server from which the backup ran.

I am not sure why when I give the answer, you ask the same question again... Yes

But we have 7.1 in our environment.But backup runs on other media server and restore is done frm other media server?

Why so?

probably because you have a force_restore_media_server setting in bp.conf on the master (or registry if windows). 

if you did as i suggested and looked at the reasons nbu would not behave as default you would find this out for yourself.

I am using OST and my STU is any available media server, in these cases backup can go to any media server and so as the restore. If restore is working fine your job is done, don't make any changes which might corrupt the environment.
