12.2.1 Backing Up the Customer Database (CDB Backup)
A distinction is made here between
● backup of customer data without HiPath Software Manager and
● backup of customer data with HiPath Software Manager.
12.2.1.1 Customer Data Backup Without HiPath Software Manager
Definition
CDB backup refers to saving the customer database (CDB) to the multimedia card MMC (Hi-
Path 3000) or copying the cyclic RAM data and saving it in two PDS (Permanent Data Service)
files (HiPath 5000).
Note: The RUN LED flashes repeatedly for a short period to signal that a CDB backup, which
takes about 30 seconds, is in progress on the MMC.
12.2.1.1.1 Automatic Customer Data Backup
HiPath 3000
A two-stage concept guarantees automatic customer data backup.
A complete CDB backup version can be found on the MMC at any time. Deltas for this backup
are stored in an SRAM area (with battery backup) in the central control board. If the SRAM area
is full, the customer data is automatically backed up. This means that the entire CDB, including
SRAM content, is copied from the SDRAM in the central control board to the MMC. The current
CDB is simultaneously stored on the MMC along with the “old” CDB, which is not deleted until
the current CDB is completely stored on the MMC.
In case of a power outage, the SDRAM content that has no battery backup is completely lost.
However, by re-accessing the CDB backup on the MMC, the system’s database can be restored
to the state it was in prior to the power outage.
Regardless of the volume of changes to the database, HiPath 3000 always automatically per-
forms a complete CDB backup at midnight, system-time.
