Binding to Server Errors

Backup follows the client/server model, where servers provide services to the client through the RPC. These services reside inside of long-lived processes, known as daemons.

For clients to find these daemons, you must register the daemons with a registration service. When the daemons start up, they register themselves with the registration service provided by the portmapper.

Backup servers provide a backup and recovery service. They receive data from clients, store the data on backup media, and retrieve it on demand. If the Backup daemons are not running and a Backup service is requested, you receive the following messages in your savegroup completion mail:

Server not available
RPC error, remote program is not registered 

These messages indicate that the Backup daemons nsrd, nsrexecd, nsrindexd, nsrmmd, and nsrmmdbd may not be running. To restart the daemons, become root and enter the following command at the shell prompt:

# /etc/init.d/networker start
