NetBackup Shared Storage Option.
SAN media servers are NetBackup media servers that back up their own data. SAN
media servers cannot back up the data that resides on other clients.
SAN media servers are useful for certain situations. For example, a SAN media
server is useful if the data volume consumes so much network bandwidth that it
affects your network negatively.
When you define a backup policy for a SAN media server, add only the SAN media
server as the client.
The NetBackup Shared Storage Option can use NetBackup SAN media servers.
To coordinate network-wide allocation of tape drives, the NetBackup Enterprise
Media Manager (EMM) manages all shared tape requests in a SAN. EMM responds
to requests from multiple instances of NetBackup master servers, media servers,
and NetBackup SAN media servers.
For shared drive configurations, the host that is configured as the EMM server is
also known as the device allocation host.
See
About the device allocation host"
EMM maintains shared drive and host information. Information includes a list of
hosts that are online and available to share a drive and which host currently has
the drive reserved. The Media Manager device service (
information changes.
Scan hosts are a component of the NetBackup Shared Storage Option.
