Managed System for SAN Storage Agent User's Guide


LAN-free Client Data Backup Scenario

The following outlines a typical backup scenario for a TSM client that uses SAN data movement.

  1. The client begins a backup operation. The client and the server exchange policy information over the LAN to determine the destination of the backed up data.

    For a client using LAN-free data movement, the destination is a storage pool that uses a device on the SAN. That device must also have a defined path between the device and the storage agent.

  2. Because the destination is on the SAN, the client contacts the storage agent, which will handle the data transfer. The storage agent sends a request for a volume mount to the server.
  3. The server contacts the storage device and mounts the appropriate media.
  4. The server notifies the client of the location where the mounted media resides.
  5. The client, by means of the storage agent, writes the backup data directly to the device over the SAN.
  6. The storage agent sends file attribute information to the TSM server, and the server stores the information in its database.
