Overview

A complete SEP sesam environment consists of different modules, which can be combined according to your needs to implement optimized backup. Modules interact with one another through SEP APIs which are also used for interaction with another software.

Essential modules of each SEP sesam environment are: SEP sesam Server, SEP sesam GUI, SEP sesam Remote Device Server (RDS), and SEP sesam Client(s). Each module is installed separately. The SEP sesam environment is managed centrally by the SEP sesam GUI.

SEP sesam also provides additional modules and functionality that enable consistent backup of databases (Oracle, MS SQL, IBM DB2, Informix SAP R/3, etc.), applications (like SAP), groupware systems, and virtualization environments. Some of these extensions are already a part of a Client package, and some require a separate license in order to function. For details on licenses, see Licensing. Check SEP sesam OS and Database Support Matrix to learn what is supported on which platforms. For list of all supported extensions and their configuration, see Extensions.

Once you have determined how you want to set up your SEP sesam environment, you can install the required components. Note that the installation procedure depends on the platform on which you are installing a SEP sesam package. Also, the procedure for installing different packages might differ.

SEP sesam Server hardware requirements

The following are the hardware requirements for SEP sesam Server or RDS. They are similar for both, except that the space for the SEP sesam database required on the file system is not necessary for RDS.

Hardware requirements for SEP sesam Server or RDS are representing the common requirements. Additional amount of RAM/CPU may be required for bigger Si3 data stores. For details, see Si3 Deduplication Hardware Requirements.

Requirements SEP sesam Server Standard edition SEP sesam Advanced Server edition SEP sesam Premium Server edition SEP sesam Enterprise Server

Microsoft Windows installation

Prerequisites

  • Before starting the SEP sesam installation, make sure that you are logged in as a local administrator or domain administrator.
  • For remote access via remote desktop connection (RDC), the RDC administrator needs the same access rights as the local administrator.
  • To install any of the SEP sesam components (SEP sesam Server, RDS, Client or GUI), you will require an installation file which can be downloaded from Windows download. Make sure to download the correct file for your processor type.
Information sign.png Note
SEP sesam RDS does not have a dedicated installation package. To install RDS, use the SEP sesam Server package.
  • If you are planning to install a server (including the GUI) or the GUI, Java Runtime Environment (JRE) must be installed on the system. For details on the required Java version, see Java Compatibility Matrix.
  • The .Net Framework 4 is required for server installation and can be deselected for all other SEP sesam components during installation.
  • x86 operating systems with more than 3.25 GB RAM must either reduce the amount of RAM to below to 3.25 GB or migrate to an x64 operating system. This is necessary because SEP sesam requires 64 KB blocks for LTO (Linear Tape Open) whereas an x86 system can only write 32 KB blocks to tape drive because the PAE (Physical Address Extension) is automatically activated. Also, a loader cannot be accessed properly by SEP sesam.
  • SEP sesam uses name resolution for server to client communication. Before installing, you should test DNS name resolution by simply pinging (using both, long and short name) from server to client and back. For details on DNS resolution check, see How to check DNS configuration.
  • Ensure that any used SCSI devices are recognized by the operating system to which you are installing SEP sesam. SEP sesam checks the SCSI bus attached storage devices during the installation and adds its data to the database. SEP sesam can only see devices recognized by the operating system.
  • It is recommended to disable firewall to avoid problems during the SEP sesam installation. Once SEP sesam is installed, you can enable the firewall with exceptions made for the SEP sesam services.
  • For details on SEP sesam default ports, see Which are SEP sesam default TCPIP ports?

Installation

SEP sesam provides four installation packages: SEP sesam Client, SEP sesam GUI, SEP sesam RDS and SEP sesam Server (includes the Client and GUI components). In the installation example below, we will use the SEP sesam Server installation package.

  1. Locate the download folder where you saved the SEP sesam installation package and double-click the sesam-srv-<Version_ID>-windows.x<SysType>.exe file to start the installation. Note that on Windows 7, you must explicitly execute the .exe file as administrator even if you are logged in as an administrator. Select your installation language and click Next.
  2. Agree to the license agreement and click Next again.
  3. Choose whether you want the the SEP sesam services to run under the Standard system accountor a Custom user account. It is recommended to give the SEP sesam Server services a Domain user account belonging to the Domain admins and the Local administrators groups. After choosing a user account, click Next.

AIX

For reference which AIX versions are supported and which components are available for AIX, check SEP sesam OS and Database Support Matrix.

Prerequisites

  • Before starting the SEP sesam installation, make sure that you are logged in as the root user.
  • Installing SEP sesam component for AIX (depending on availability either SEP sesam Client or Remote Tape Server can be installed) requires special RPM packages to be installed with the standard RPM package manager (part of the AIX default installation). You can download the required RPM packages from the SEP Download Center and copy them to the AIX system to /tmp/rpm-packages/. Then install the package via RPM:
  • cd /tmp/rpm-packages/
    rpm -i *
    
  • SEP sesam GUI requires Java Runtime Environment to be installed on the system. For details on the required Java version, see Java Compatibility Matrix.

SEP sesam Remote Tape Server or Client installation

  1. Download the relevant SEP sesam package from the SEP Download Center and copy it to the /tmp directory on your AIX system. The following example shows the installation of the sesam_rts package. The procedure for installing SEP sesam Client is slightly different; the name of the package is substituted with sesam_cli.
  2. Unzip the archive by using the following commands:
     gunzip sesam-rts-<version>-aix_powerpc.tgz
     tar -xvf sesam-rts-<version>-aix_powerpc.tar

    A new directory sesam_rts_<version> is created:

     # tar -xvf sesam-rts-4.4.2.58-aix_powerpc.tar 
     x sesam_rts_4.4.2.58
     x sesam_rts_4.4.2.58/aix_rts.4.4.2.58.tgz, 22440192 bytes, 43829 media blocks.
     x sesam_rts_4.4.2.58/sm_setup, 2168068 bytes, 4235 media blocks.
  3. Go to the unzipped directory
    cd sesam_rts_<version>
  4. Execute the setup executable sm_setup as the root user:
     # cd sesam_rts_<version>
     # ./sm_setup
  5. Follow the wizard and select the relevant components that you wish to install, tapeserver or client, respectively:
     # ./sm_setup
     Found 1 valid archive(s): 'aix_rts.4.4.2.58.tgz,'.
     What do you want to install? (tapeserver,client)
     tapeserver
  6. Set the installation directory; the recommended place to install sesam is /opt/sesam. Make sure that there is at least 10 GB of free disk space available. Optionally, choose another installation directory that has enough free space:
     In which directory do you want to install (If not existing it will be created): 
     '''/opt/sesam/'''
     In which directory do you want to install (Read-Write): 
     '''/opt/sesam/'''
  7. Specify the SEP sesam Server hostname in your environment; you must provide the DNS hostname of your backup server. The DNS Server must be correctly resolved on the AIX system. For details, see How to check DNS configuration.
     To which SEP sesam Server should be connected?
     '''backupserver.hostname'''

Once you specify all required information, SEP sesam software installation and configuration is started. If you have problems with starting SEP sesam services, check the Troubleshooting Guide.

Mac OS X

Prerequisites

  • Before starting the SEP sesam installation, make sure that you are logged in as a local administrator or domain administrator.
  • If you are planning to install a GUI, Java Runtime Environment must be installed on the system. For details on the required Java version, see Java Compatibility Matrix.

Steps

SEP sesam does not provide a dedicated MAC OS package. You should download the latest SEP sesam Linux GUI package from http://download.sep.de/linux/repositories/debian/pool/main/s/sesam-gui/, copy it to your MAC system and extract it with the command

 ar x <sesam-gui_4.4.3-xx.lenny_i386.deb> && tar xfz data.tar.gz

and copy the extracted directory to your program files directory; then use the <SESAM_BIN>/gui directory:

/opt/sesam/bin/gui/sesam_gui -S <hostname_backup_server>

Or, in case your backup server is a Linux system, you can connect via the command line (X must be enabled) and start the GUI:

/opt/sesam/bin/gui/sesam_gui -S <hostname_backup_server>  

SEP sesam for Mac OS X supports standard file backups with ACL's. Disaster recovery is not supported!

If you have a problem or questions regarding installation, also check FAQ: Installation and configuration.

Univention UCS

For the list of supported Univention UCS versions and available SEP sesam components for UCS, check SEP sesam OS and Database Support Matrix.

Prerequisites

  • Before installing, you should test the DNS name resolution by simply pinging (using both, long and short name) from server to client and back. For details on DNS resolution check, see How to check DNS configuration.
  • It is recommended to disable firewall to avoid problems during the SEP sesam installation. Once SEP sesam is installed, you can enable the firewall with exceptions made for the SEP sesam services.

Installing SEP sesam on UCS

Option 1: Installing via Univention App Center (only SEP sesam Server and Client)

  1. Open the Univention Management Console in your browser.
  2. Go to Software -> App Center.
  3. Search for SEP sesam.
  4. Install either SEP sesam Server or SEP sesam Client.

Option 2: Installing via SEP Debian Repository

  1. Open a terminal session as root user.
  2. Enable Univention unmaintained repositories with the following command (this enables the UCS system to install the dependencies for SEP sesam):
    ucr set repository/online/unmaintained=yes
  3. Add the SEP Debian Repository as described in Debian Repository:
    • UCS 4.2 is based on Debian 8 Jessie.
    • UCS 4.3 is based on Debian 9 Stretch.
  4. Update repositories by using
    apt update
  5. Install SEP sesam package via apt: For example, to install the SEP sesam Server package, use
    apt install sesam-srv

    Other options are listed here: Debian Repository.

Option 3: Installing manually

  1. Open a terminal session as root user.
  2. Enable Univention unmaintained repositories with the following command (this enables the UCS system to install the dependencies for SEP sesam):
    ucr set repository/online/unmaintained=yes
  3. Download the desired installation package from the SEP download center.
    • UCS 4.2 is based on Debian 8 Jessie.
    • UCS 4.3 is based on Debian 9 Stretch.
  4. Update repositories by using
    apt update
  5. Install SEP sesam package via apt:
    apt install /path/to/downloadedpackage

Configuring UCS firewall

By default, Univention firewall is included in all UCS installations with all incoming ports blocked. You have to enable access to certain ports to allow SEP sesam to work.

Information sign.png Note
Installing a SEP sesam App Center package will automatically open the required ports for SEP sesam except for the Si3 Replication and REST API.

Disable UCS firewall

You may consider deactivating the UCS firewall completely by setting the Univention Configuration Registry variable security/packetfilter/disabled to true:

ucr set security/packetfilter/disabled=yes
service univention-firewall restart

Use SEP sesam with enabled UCS firewall

Check the list of required ports for SEP sesam: List of Ports Used by SEP sesam.

To open a port or a range of ports, use the following commands:

ucr set security/packetfilter/tcp/portnumber_or_portrange/all=ACCEPT
service univention-firewall restart
Client firewall settings

If you want to backup a client behind a firewall using STPD, you have to specify an open port range in the client's STPD Options as follows:
Open SEP sesam client Properties and switch to the Options tab. If you have installed a client from the App Center, the port range is 11002-11007.

For more information on client configuration, see Configuring Clients.
