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.
Responding to a mount request
Responding to a mount request includes providing the required media or any copy
of media and telling Data Protector to proceed with the restore.
Parallel restores
What is a parallel restore?
In a parallel restore, interleaved data from multiple objects is read concurrently from
media in a single path and restored. A parallel restore significantly improves restore
performance when restoring multiple objects from the same media. For more
information, see Figure 66 on page 229.
How does it compare to a standard restore?
Data from multiple Disk Agents is (most of the time) multiplexed and stored on the
media. See Figure 41 on page 149. In a standard restore, Data Protector reads
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.
