Mount Requests In A Restore Session; Parallel Restores - HP B6960-96035 Concepts Manual

Mount requests in a restore session

What is a mount request?
A mount request appears in a restore session when the media needed for restore are
not available in the device. Data Protector allows you to configure a desired action
that should happen when a mount request appears.

of media and telling Data Protector to proceed with the restore.

What is a parallel restore?

multiplexed data from the media and assembles only the parts needed for the selected
object. When the next object is restored, Data Protector must rewind the media and
read the parts for the other object, assuming both objects are on the same medium
and written using multiplexing.
