SEP sesam Install

• Sesam Server

– Main memory 1-2 GB

– Java 1.6 (Sun, IBM or openJDK)

– PostgreSQL on 64-bit Linux

– Sesam VAR area size between 30 and 50 GB or more

– Depends on the backup and media strategy

• Storage Hardware

– On Linux: all SCSI/SAS- and FC-HW direct connected will

work

– On Windows: Manufacturer drivers have to be installed

– If the hardware is visible to the operating system, Sesam

can use it

Backup in Virtual Environments

• Citrix XENserver

–Online hot and warm module using the XENserver API

–Agent-Less Technology

• VMware vSphere/ESX

–Directly via ESX host

–VCB-Proxy

–vStorage APIs for Data Protection (VADP)

• MS Hyper-V

–File consistency with VSS

• Open source Xen

–Backup using LVM snapshots

Virtual Guest Online Backup


• Multinode Aware

– SEP sesam Backup Server looks

at the cluster and will talk to all the

hosts and determine where the

guest is for the backup

Virtual Server Restore

Virtual Cluster

Virtual Host Hypervisor 1


Shared Storage




• Multinode Aware

– After the backup is found, the

communication stream will be

isolated to the correct host

Virtual Cluster



Shared Storage




• Multinode Aware

– A host can be specified to direct

the restore to a specific location

Virtual Cluster



Shared Storage




• Multinode Aware

– SEP sesam can be used to keep

virtual guests synchronized between

hosts or virtual clusters

– This can be used with the remote

device server to synchronize servers

between locations

• XML Archiving – Capable of arching Oracle in XML

format

• Wizard based configuration

Backup in SQL Environments

• Microsoft SQL

– Uses standard Windows Agent to support Full Copy,

Differential and Incremental backups

– VSS aware

– Point in Time Restore

– Cross Restore of Databases into one another or another

instance

– Log backups can be done with or without truncate options


Backup in SAP Environments

• SAP software

– Close partner

– Working together for over 15 years

– Highest level of certification of any third party vender

– Off Host Backup

– Supports other SAP R/3 Applications: Oracle DB on SUN,

Oracle DB on Reliant Unix, Oracle DB on Tru64, MaxDB on

AIX, MaxDB on Windows 2003 & 2008


Backup in a Novell Environment

• Backup over Novell Storage Management Services

(SMS) and Target Service Agents (TSA)

• There is no Sesam client needed for OES NetWare, it

uses the TSA

• The backup server or One OES2 Linux host has to

work as Data Mover

• There must be a valid SLP configuration to backup

cluster resources

Novell Cluster Services

Backup with SEP

Backing up Novell Cluster Services using SEP sesam

The SEP sesam backup recovery solution has been certified by Novell for use on

all platforms. The Novell cluster backup arena is a reliable and important part of

the backup solution provided to customers and partners.

SEP has more features than our largest competitors: Syncsort, NetBackup,

Legato, Tivoli., at a price that compares with BackupExec

Basis

A Novell cluster consists of several physical cluster nodes, sharing common

access to the storage device(s). Services such as iPrint, GroupWise and NSS will

be referred to as ‘Resources”.

LAN Free Backup

• Remove backup traffic from the main network with SEP sesam

backing up a Novell cluster to a SAN disk or tape

• Gain performance advantages on the network by removing

backup traffic and increase backup performance by backing up

with SAN speeds

• This can all be done on a Novell cluster (or other SAN attached

nodes) by using the SEP sesam SAN Remote Device module.
