Goal

Restore of a SESAM server without sm_recover only using sbc directly from still existing virtual disk images.

This example recreates the following situation: a SEP sesam server with a 1 GB media pool backup (location /backup) which contains 9 virtual disk media. The SESAM_BACKUP and other backups are located on these disk media.

A disaster occured and only the disk media are existant. Now the state of the SEP sesam server before the disaster is to be restored from these media.

Course of Action

1) Making sure the disk media are availible in the directory /backup/
2) Installation of a SEP sesam server with identical version of the original system
3) Creating an identical media pool (name: backup)
4) Archive adjustment of the media pool with automatic initialization (no overwriting!!)
5) Loading the disk medium with the last SESAM_BACKUP to the drive
6) Searching the last SESAM_BACKUP to disk medium
7) Restore via sbc.

important information here:
1) Segment Number (3)
2) SaveSet Name (SC20090615095925)
3) Tape Label (BACKUP00001) 
4) Tape ID (1)
Restore is executed with the sbc command which contains following information: 

sbc -r -l FULL -C <client_host>:11001 -S <server_host>:11001 -d SMS:<tape_device> -t <tape_name>:<tape_id> -s <saveset_id> -n <segmentnumber> -R / -o overwrite
