About the NDMP restore process
Because of the design of the NDMP protocol, only an administrator on a NetBackup server (master or media) can restore files from NDMP backups. During a restore, the administrator browses the file catalog and selects files from NDMP images in the same manner as for standard backup images.
The following events occur during a restore, in this order:
The NetBackup for NDMP server looks in its Enterprise Media Manager (EMM) database for the tape that contains the backup, and asks ltid to mount that tape.
ltid on the NetBackup for NDMP server sends the necessary NDMP commands to load the requested tape on the storage device.
NetBackup sends the NDMP commands that are necessary to have the NDMP server application perform a restore operation to the disk. The restore data travels in one of two ways:
The NDMP server application sends status about the restore operation to the NetBackup for NDMP server.
The following figure shows the NetBackup processes involved in NDMP restores.
