Operate test scenarios

To operate test scenarios in many cases you have to clear the SEP sesam environment after the test and re-run scripts. The following sequence offers you a workaround to do that.

Right after a new installation of a SEP sesam Server has finished export the database
sm_db export -f <smdb_file>
Example: sm_db export -f /srv/sesamdb_myserver.sql
If you like to recreate your work from the Sesam base configuration do the following:
1. Clear the Sesam-DB by recreating the database
  sm_db import -f /opt/sesam/skel/db/<dbtype>/sesam_db.sql
  <dbtype> means the type of database your SEP sesam is using (sqlite for SQlite or pg for PostgreSQL).
2. Import the <smdb_file> to get the basic status after installation of the SEP sesam Server
  sm_db import -f <smdb_file>
  Example: sm_db import -f /srv/sesamdb_myserver.sql
3. Run your SEP sesam CLI script again

New SEP sesam Environment (backup environment example)

This chapter describes the requirements to create a new SEP sesam environment as showcase.

Network overview

Description

The new SEP sesam environment should accomplish the following requirements.

Remove the SEP sesam install defaults.
Register a Linux and a Windows backup client
On SEP sesam Server smsmrv should work a disk store with 2 mediapools for backup to disk.
The backup client xubl01 should act as SEP sesam Remote Device Server (RDS) with a mediapool for backup to disk.
Create the necessary jobs for restore of the SEP sesam Server and the Windows client.
Backup the Linux server configurations (/etc directory).
Combine different backup tasks into taskgroups.
Backup strategy
- Linux server systems and configs from Monday to Friday as full backup.
- The Windows server as full backup every weekend.
- The Windows server files backup incremental from Monday to Friday.
- On the last day of every month backup the Linux server systems to the RDS disk.
- Migration the disk backups to a different mediapool ...
  - ... from Tuesday to Friday migrate all backups from mediapool vda to vdb from yesterday to today.
  - ... on Monday migrate all backups from mediapool vda to vdb from 3 days before up to today.
Start two command events
- The 1st generate a list of the used media for backup and migration
- The 2nd is for Notebook backup. It checks if the Notebook is connected into the network. If yes, then the backup will be started.
Change the sm_newday event from running at 08:00 a.m. every day to running at 06:00 p.m. from Monday to Friday.
Activate the SEP sesam Server notify, alarm and disaster interfaces by copying them from the templates to ./bin/sesam directory
Create an email account sesam for sending standard emails raised by the interface file events.
Create a SEP sesam metadata backup twice a day.
Provoke some test backups.
At the end execute a SEP sesam metadata backup. After that you can check if an email has been sent.

Script file

The following configuration can be executed line by line. All lines beginning with a hash sign are comments. Either you copy sm_cmd... commands line by line to a console of the SEP sesam Server and execute it or you can copy them to a script file to run it in one step and automatically (e.g. Create_Sesam_Env.sh below).

#!/bin/bash
#--- load SEP sesam profile
