Welcome to SEP sesam
SEP sesam | Backup - Restore - Disaster Recovery
The SEP sesam backup solution has been specifically designed for Server/Client environments. From a single data server to large, complex heterogeneous data centers with very large data bases and scalable Storage Area Networks (SAN), SEP sesam provides consistent, accurate, reliable and efficient backup and recovery of enterprise critical data. The modular design means that SEP sesam is perfectly adaptable for all companies, regardless of size or backup strategy from centralized to decentralized backup strategies.
To allow backup of large amounts of data in the shortest amount of time SEP sesam offers true multi-stream/multiplexed backup. From five (5) data streams with our Standard Server offering up to 64 data streams with the Advance Server license. Opening up multiple streams for backups minimizes the amount of system resources for both planned and unplanned data backup tasks.
Online modules for all popular database and groupware solutions offer the ability to back up while the applications are active, providing the highest data availability possible. Restores are also possible while the apps are running, including the ability to restore single mail boxes and single mail restore.
SEP sesam has extremely efficient, patented algorithms. Their implementation requires only limited processor overhead, and combined with our high transfer rates (over 400GB/hr) we deliver some, if not the best, performance in the industry. SEP sesam is platform agnostic, it runs exactly the same on Linux, Unix or Microsoft. The platform independent GUI allows backup and restore in the Network, or remotely via WAN, VPN, etc.
SEP sesam supports all standard backup devices, disk, tape, tape autoloaders, tape libraries. SEP sesam delivers Virtual Tape Libraries (VTL) as a standard component of the base product. Using economical, high-performance disk drives SEP sesam delivers a lasting, sustainable solution for the backup and recovery of enterprise critical data. Disk-to-Disk-to-Tape (D2D2T) functionality delivers further enduring security for maximum performance by backup and restore.
SEP sesam is an automatic data backup system for heterogeneous computing environments. All standard tape drives, disk drives and auto loading devices are supported and can be used for backup. In order to easily and effectively construct the configuration of the system, a design based on the following six basic components was chosen.
- Local or remote storage device
- Robot loading the media from/to the drive
- Computer from which the data is backed up
- Repository for the saved Data
- Description of a Backup or Restore
- Start time of different activities
- Backup Server on Linux (including Novell OES), Windows, freeBSD und Unix
- Clients for Linux, Windows, many UNIX derivatives, NetWare (Klient free support) and VMS
- Fast and easy installation on standard O/S configurations. Less than one minute on SUSE and RedHat!
- SEP sesam creates a test backup and restore upon installation to verify system is running
- JAVA based graphical user interface. (GUI)Master GUI design provides full access to clients and servers
- Support for all automated tape drives or autoloaders
- Full, Differential, Incremental and Copy (for off-site storage) backups are possible
- Scheduled backups using user/administrator selected events
- Media administration and setup via GUI or Master GUI. Allows flexible media strategy and easy task selection.
- Powerful scheduling tool
- SEP NEWDAY allows backups to record on the same calendar day, ie. backups started on Friday and finishing on Monday before 8 am can have the same backup day
- event control can be used for any external applications
- Scheduler allows development of flexible media strategies to avoid delays and missed backups
- Selection of optimal data paths throughout the network
- User configurable Command Line interfaces (Alarm, Pre/Post, Notify, Disaster, etc.)
- Fast data restore via effective administration of the backup savesets and implementation of well-designed search algorithms
- Full and selective restore to the original paths or in newly-created directories with or without preserving the original path structure
- On-line modules for database backup DB2, Informix, MS SQL, mySQL, ORACLE, SAP R/3 and others are available, i.e. backup performed without stopping the database
- Optimized tape backup using parallel backup streams for multiple clients; sesam Multiplex Streaming allows up to 64 continuous backup data streams
- Migrate from savesets on disk to tape; DISK-to-DISK-to-TAPE
Principle of SEP sesam
The SEP sesam principle takes into account the interaction of each component of a data backup, server, client, data store (local attached disk, NAS, SAN, USB disk drives, tapes drives, networks, firewalls, etc. After the installation of a SEP sesam server the System Administrator has full control to set up the software to fit the backup environment. This user must setup of the storage hardware, the configuration of the drive groups and drives and the initialization of media pools with the corresponding physical and/or virtual media has to be accomplished. This overriding design principle gives the administrator the ability to create a backup environment uniquely applicable to the user environment. Flexibility, Performance, Data Availability and Security are the foundations that set the framework for SEP sesam.
The SEP philosophy: Backup all the data required in the shortest possible time, secure it in the safest manner possible, restore it in the shortest window of time. Allow for recovery from an inadvertent file deletion to a full system disaster. One tool for all environments. A tall order - SEP delivers.
The red arrows from the media pool to the right (see figure above) shows the direct relationship of the media pools to a drive group. To that drive group, 1-N drives are assigned. Next the storage media (tapes, virtual disk media, removable media etc.) can be assigned to the appropriate media pool. The media pool is used to assign the BACKUP LOCATION. The data source is directly related to a task. By specifying the data source you determine WHAT should be backed up, nothing more. The SEP sesam SEPuler or scheduler connects the media pool to the data. This scheduled timetable specifies WHEN something should be backed up, where the data will be stored and for how long. The final choice is the type of backup to be performed. Let's call it HOW we will backup (e.g. Full, Diff, Inc backups) and we define WHERETO (Media Pool) the backup should take place. All reside in the SEPuler, the heart of the backup environment.
After installing SEP sesam it is recommended to proceed the basic configuration in the following order:
- Create the clients. Install client software on target computers to be backed up along with any online modules required.
- Define tasks (WHAT should be backed up).
- Define timetables (WHEN the backup takes place).
- Link the timetable with an event (WHAT will be backed up WHERETO and HOW).
This is a step-by-step description how to configure SEP sesam to perform a simple data backup using the components described above. The detailed description of the interface elements can be found below.
Directory structure of SEP sesam software
A detailed description of the different Sesam directories can be found in the Sesam Administration Guide.
The tasks tab allows the user to set events for backups, restores and migration of data. For administration there are three tiers of operators: by Client, By Group and Backup Plan (Tree structure is on the left side).
The chapter SEPuler describes Time Management within SEP sesam. Here is a discussion of the user interface for backup schedules, events and calendar attributes with in SEP sesam.
Backups are an integral part of the Sesam Information System. Only "completed" backups are displayed, along with a multitude of display, information and filtering possibilities are offered.
Monitoring shows all running processes/daemons as well as the status of all running disk drives.
Sesam creates two protocols or log files for each backup day, the status file and the day protocol. This information is stored as files in <SESAM ROOT>/var/prot . It can be utilized for other tasks and can be transmitted in print, email or web forms if desired by using post commands to transmit data for reporting and control if desired.
Caution: A backup day is framed by two NEWDAY events.
The selection of time interval enables restrictions to output. Start this by clicking the Show button.
Menu Bar and Tool Bar
In the menu bar you can find the menus File, Activities, Configuration, Window and Help. Below the menu bar you will find a toolbar for easy access to these important elements:
In addition, other buttons can be added dynamically, e.g.
- cyclical Show-Updates for "Job Status" Working Window (e.g. "Job Status->Backups").
