Topology

The Sesam backup environment including the hardware, computers, backup devices, etc is referred to as Topology .

These interconnected computers (clients and servers), which can be grouped into locations and sub-locations as well as the storage devices ( loaders, drives ), which are available for Sesam locally or attached to clients (Remote Device).

The menu item Topology shows all Sesam locations, clients, loaders and drives known to the Master Server as well as the media within the devices. By clicking the symbols they can be expanded into the subordinate structures via a function tree. Each client is related to a location and each loader and drive to a client. By marking (clicking on one of the tree components and clicking the switch properties), the user opens the entry screen for the components.

A Master Sesam at the highest level presents all currently accessible usual Sesam computers. With a mouse click their individual data can be viewed.

A 'usual' Sesam server shows one node only, namely itself.

To create a new location independent of another location, start at Topology and click the button New Location .

A client is always related to and created within a location.

Server Properties

Note The parameters of the server cannot be edited here.

Location Properties

Location is defined as a group of clients and/or further sub-locations. This should help to organize larger networks so that computers in a building, an external office etc. can be managed and represented in separate units.

New locations can be configured from a Sesam server or from an existing location (sub-location). Sesam sets up a tree-structure for all locations(e.g. USA-Colorado-Boulder-SEP Software) offering greater visibility.

Client Properties

Clients are defined as computers in the network from which data are to be saved. The computer on which Sesam is installed is called the server .

If a client is not available for backups (e.g. because of a shutdown), the SysAdm can select the check box locked for backups and prevent unnecessary access (locked clients are marked with off under Topology). If an unavailable client is not locked, the SEPuler will continue to look for it to perform the scheduled backup.

Warning: Once selected locked for backups the client will no longer be backed up, even if on the event calendar. The SysAdm must remove the check to reestablish the backup schedule.

Note If several interfaces are entered, separate them with a Return or a Blank.

In this field the SBC (Sesam Backup Client) client software version is shown.

Locked from backup 

If a client needs to be excluded from the backup plan for technical or other reasons you can deactivate it here.

Firewalls

Normally when initiating backups of clients Sesam uses the ports randomly provided by the operating system. However, this is not allowed if the client is located behind a firewall.

If there is a firewall in place a port range can be pre-determined by using the command sm_ctrlc for communication with the clients:

Access Options input -o port=firstport-lastport

Another method to connect through the firewall is to configure a Singleport connection ( -s ), where Sesam uses only one port (by default 11301).

Note: This must not be done for Remote Tape Servers.

The return ports from client to the Sesam server are placed in STPD Options , e.g. 11003-11005. The data can now be transferred over these ports. Each parallel backup requires two separate ports. For each additional parallel running backup from a client you will need to assign a further 2 ports, e.g. 11003-11007).

Note: Further information regarding Firewalls can be found in the Admin Handbook.

Additional Properties

In the event you are trying to backup an OES-NetWare or a OES-Linux client the SEP sesam data mover connects to the TSA provided by Novell. To communicate with the various TSA's you will need the following information.

User  

User Name authorized for communicating with the TSA's.

NetWare Password  

NetWare User's Password, that is communication with the TSA's.

Repeat Password  

Re-enter Password to insure it is correct.

Data Mover  

The Data Mover is the Host, where the sesam/Novell client with the normal base software patches is installed. The sesam-Novell client is needed to start the communication between the Sesam Server and the running TSA. That means that the sesam-Novell client can be installed on any Linux computer/server. The only requirement is that it have either sesam client or server software properly installed. The resolved DNS sesam client or server will then be entered as the data mover. In the event specialized backup methods are used, the settings will be required to be entered in the Tabs within the masks, and they must be visible to the SysAdm.
