Overview

SEP sesam Client is a system that has a SEP sesam Client package installed, is added to the SEP sesam environment as a client and is included for data protection in the backup plans. Clients may be workstations, PCs, virtual machines or file servers with gigabytes of data.

The abbreviation SBC (sesam backup client) is used in a more technical sense for programs, which are executing backup, migration and restore tasks. SBC collects and consolidates the backup data on the client system, and delivers it to Sesam Transfer Protocol Server (STPD – a service that requests the backup data from the SMS Server and manages the data flow between the SEP sesam Server and a client). The SBC module can also be controlled directly without other SEP modules by using SEP sesam CLI.

You configure a new client in the Main selection -> Components -> Topology -> New client.

Procedure

  1. In the Main selection -> Components -> Topology, select the desired location (LOCAL is always created by default), and then click New client. Enter the name of the client – this has to be the network host name of the computer. The name has to be resolvable either by DNS or hosts file. If there is a name server (DNS) in the network, SEP sesam automatically selects the TCP/IP address. Otherwise you have to enter it manually in the etc/hosts file.
  2. From the Platform drop-down list, select the relevant platform: Windows, UNIX, VMS or NETWARE.
  3. From the Operating system drop-down list, select the relevant client's operating system.
  4. From the Access mode drop-down list, select the communication method and access type between the client and the SEP sesam Server. The following access modes are available: CTRL (default access mode up until version 4.4.3.48 Tigon V2), SMSSH (SEP sesam SSH based control communication; default access mode as of version 4.4.3.60 Grolar), PROXY (available vendor-specific protocols are: vSphere (vCenter Server), Citrix Xen Server, NetApp and Novell SMS for NetWare 5.1/6.0/6.5), SSH (secure shell), and RSH (remote shell).
  5. Optionally, specify the following fields.
    • The Last message field is intended to display the most recent system status message for the existing client.
    • The Notes field provides an option to comment your configuration.
    • The Interfaces field is meant only for specifying additional interfaces for SEP sesam Server or Remote Device Server (RDS). If there is an additional network for backups available, 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 otherwise the connection to the SEP sesam Server will fail. The network protocols for data transfer can be set by using the common prefixes ftp:// (default), http:// or https://. For each protocol one interface has to be added in the interfaces box separated by single spaces. One interface for the HTTP protocol http://<hostname>:11000 and one interface for the HTTPS protocol https://<hostname>:11088.
    • Locked for backups is used only in special cases, when you want to exclude a client from backup for technical or other reasons. Checking this option will deactivate your client from all scheduled backups until this option is set.
    • Client is a virtual machine should only be selected if you are adding a virtual machine.

  6. If your client is behind a firewall, you have to configure the communication ports. By default, SEP sesam uses random ports which are specified by the operating system. However, if you want to back up a client which is behind a firewall, you must manually define the ports. Switch to the Options tab. The available options depend on the client type.
    • In the Access Options field, enter the port over which the client is reachable by using the command -p <port_no> (e.g., -p 17301). The default listen port for the CTRL daemon on the clients is 11301, and for SMSSH 11322.
    • Use STPD Options to set up the communication port for transferring data from backup client to the SEP sesam Server. Note that each backup running simultaneously on a client requires two ports; e.g., three simultaneous backups on the backup client use ports 11002-11007. When the HTTP protocol is used for data transfer (SEP sesam Server interface is http://<SEP sesam server>:11000), the TCP port 11000 is used.
    • Listen Port is the initial STPD port for device servers (SEP sesam Server, RDS). It is 11001 by default. If you need to alter the default port, insert a new port number.

  7. If you are configuring clients that must be backed up by special task types, additional settings must be specified. A third tab is available for the following task types: Micro Focus Open Enterprise Server (formerly Novell), VMware, Citrix XEN, MySQL, PostgreSQL, NetApp, RHEV. For example, for Micro Focus OES or NetWare server backup you have to specify the login data for the eDirectory and select the appropriate data mover. For Micro Focus, this is a SEP sesam Micro Focus (formerly Novell) Client which is installed on Linux computer with Micro Focus Storage Management Services (SMS).
    For more information on specific task type, see the respective wiki articles under Extensions.

  9. Once all the options are set, click Create. A new dialog box appears, asking whether you want to create a new backup job for this client. Click Yes to create a backup task or No if you intend to configure your backup later. For details, see Standard Backup Procedure.
  10. Your new client is displayed in the Topology content pane.
