3-2 Network Wide Backup & Restore Engineering Considerations

Integrated Network Management Rel 1.0 Standard July 1999

Estimated Time to Backup an OPC

The estimated time for OPC backup to complete is dependent on the following:

• available bandwidth

• number of controllers

• concurrent jobs setting under the user preferences of the GUI

Estimated Time to Backup an NP

The estimated time for NP backup to complete is dependent on the following:

• # of NPs on the same MOA

• available bandwidth

• number of NPs

Additional Capacities

The following table shows the engineering capacities for the backup and

restore GUI usage, as well the number of simultaneous backups and restores

allowed.
