Topology

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

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

The menu item Topology shows all SEP 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 assigned 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 'regular' SEP sesam computers. With a mouse click their individual data can be viewed.

A 'regular' SEP 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 assigned to and created within a location.

Note The parameters of the server cannot be edited here.

Location Properties

Locations are 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 SEP sesam server or from an existing location (sub-location). SEP sesam sets up a tree-structure for all locations(e.g. USA-Colorado-Boulder-SEP Software) offering greater visibility.

Client Properties

Clients are the computers in the network (including the SEP sesam server) that you want to backup and restore.

The following screenshot shows the input fields and functions of clients. Note: these options are different when the client is created and when the client is selected and edited. Once a client is added its name cannot be edited. If its name is incorrect or not resolvable in the network the cilent has to be deleted and added again.


Clientproperties 4.0 en.jpg


Location
Predefined location. A client always has to be assigned to a location.
Operating System
Enter the operating system of the client you want to backup. If the right one isn't on the list choose a similar one.
Access Mode
Select the access mode for the server-client communication. The default setting is CTRL. SSH and RSH are selectable, too. The communication method SSH is described in the FAQ's.
Last Message
The most recent system state (e.g. communication error during client creation).
Notes
Optional comment by the user.
Interfaces
Only edit this field if the client is the SEP sesam server itself. If there is an additional network for backups the resolvable and changed DNS-name of a second network card of the SEP sesam server can be entered into a new line. If several network cards are available they need to be known to the DNS because otherwise the connection back to the SEP sesam server fails. These interfaces can then be predefined in backups and schedules.

Note If several interfaces are entered separate them with a return or a blank.

SBC Version
This field shows the SBC (SEP sesam Backup Client) version of the installation.
Locked from backup
If a client needs to be excluded from the backup plan for technical or other reasons you can deactivate it here.
Note:

If this switch is set the client can no longer be backed up until the setting is removed. Even if the client is part of the pre-established backup schedule.

Firewalls

Firewallclients 4.0 en.jpg

By default SEP sesam uses ports that are assigned randomly by the operating system for its data connections. If clients that are behind a firewall are to be saved these ports can be defined.

Access Options
In order to enable communication between the SEP sesam server and the client -s has to be entered here. This way a Singleport connection is set. The port that's being used is then 11301 and it is used to execute commands and to carry logfiles.
STPD Options
The STPD options are used to define the backports from the clients to the SEP sesam server, e.g. 11003-11006. These ports are then used to carry data during backups and restores. For each backup that runs parralel 2 ports of a client are needed.
Listen Port
The default STPD-port for Remote Device Servers (incl. SEP sesam server) is 11001.

Note: For more information about firewalls please check the Administrator Manual.

Additional Properties

If 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.


Netwareaccess en.jpg


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
Enter the password again to make sure 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 SEP sesam Server and the running TSA. This means that the sesam-Novell client can be installed on any Linux computer/server. The only requirement is that it has either the SEP sesam client or server software installed properly. The resolved DNS sesam client or server will then be entered as the data mover. In the event that 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.
