Migrating a Disk Library - Using a Local Mount Path

If you had a disk library configured as a local mount path in the old MediaAgent and you had scheduled regular Auxiliary Copy operation to a secondary copy, you can restore the data to the local mount path in the new MediaAgent

About This Task

The following steps assume that you had previously scheduled regular Auxiliary Copy operations from the local mount path in the old MediaAgent to a secondary storage (tape media).

Note that there could be a potential data loss if regular Auxiliary Copy operations were not scheduled or if the most recent Auxiliary Copy job did not pick up the latest data residing in the disk library.

This task uses examples to restore the data from secondary copy to a new primary copy.

Use the following table as a quick reference.

Names Description
new_MediaAgent New MediaAgent
new_DL New Disk Library configured in the New MediaAgent
old_DL Old Disk Library on the Old MediaAgent
Old_Primary_Copy Primary Copy for the old disk library on the Old MediaAgent
sec_copy Secondary Copy that used the old disk library as the source and the secondary storage (tape media) as a target
New_Primary_Copy Primary Copy for the new disk library on the New MediaAgent
