The entire OpenScape 4000 system including all its access points/OpenScape
4000 SoftGates and survivability units is only configured in the host
system.
Local administration of the feature is not possible at the survivability
unit with the exception of OpenScape 4000 Assistant, Backup and Restore.
A special backup of the OpenScape 4000 system database (OpenScape
4000 Assistant > Backup and Restore in the host system) is performed
at set intervals (usually once a day).
The survivability units perform continuous checks (every 10 minutes)
to see if a new OpenScape 4000 database backup is available. If this
unit is not actively controlling an access point/OpenScape 4000 SoftGate
(emergency mode), it downloads the saved data and incorporates it by
means of a reload (OpenScape 4000 Assistant > Backup and Restore on
the survivability unit).
The backup data is stored on a file server. This file server may be
located in the customer’s computer center. You can also use the OpenScape
4000 Manager platform as a file server.
The daily backup is configured on the file server in such a way that
it always contains the complete system with database, patches and software.
However, transmission from the host system to the file server and
from the file server to the survivability unit is optimized. Only different
data is actually transferred.
