NDMP restore logging

Figure: NDMP restore process

NDMP restore process

The basic processing steps for an NDMP restore operation are as follows:

NDMP restore procedure

  1. An administrator at the NetBackup Administration Console on a NetBackup master server or media server initiates a restore job by browsing the images catalog and by selecting the files to be restored from the NDMP images. This process is similar to selecting files to be restored from standard backup images. The NetBackup master server identifies the specific media that is required to perform the restore. In this diagram, the media is a tape volume.
  2. After the master server identifies the data to be restored and the media required, it submits a restore job. The Job Manager (nbjm) then requests the required resources. This resource request causes the allocation of the media that contains the data to be restored. In this example, a tape drive is used during the restore operation.
  3. The master server contacts the media server that participates in the restore job, and starts the Restore Manager (bpbrm) process to manage the restore job. bpbrm starts the Tape Manager process (bptm), that queries nbjm for the tape volume. Then, bptm requests that the logical tape interface daemon (ltid) mounts the tape.
  4. On the NetBackup for NDMP server, the NDMP agent (ndmpagent) connects to the filer and issues NDMP commands to mount the tape that is directly attached, and ltid sends NDMP commands to mount the requested tape on the storage device. Or, the media server itself issues tape mount requests much like a regular media manager storage unit.
  5. One of the following occurs, depending on the type of NDMP restore operation:

    • Local restore. NetBackup sends the NDMP commands to the NDMP server to initiate the restore operation from a tape drive to a local disk. The restore data travels from a tape drive to a local disk on the NDMP host without traversing the LAN.

    • Three-way restore. The NetBackup media server establishes NDMP communications with both of the NDMP servers that are involved in the restore. To initiate the restore of data from tape on one NDMP server to disk storage on the other NDMP server, the media server sends NDMP commands to both NDMP servers. The restore data travels over the network between the NDMP hosts.

    • Remote restore. NetBackup sends the NDMP commands to the NDMP server to prepare the server for the restore. bptm on the media server reads the restore data from tape and sends it over the network to the NDMP host where the data is written to disk storage.

  6. The NDMP server sends status information about the restore operation to the NetBackup for NDMP server. Various NetBackup processes (nbjm, bpbrm, bptm, and others) send job status information to the master server. The Jobs Database Manager (bpjobd) process on the master server updates the restore job status in the jobs database. You can view this status in the Activity Monitor.
