Does PowerKeeper support redundancy and high-availability?
PowerKeeper supports several layers of fault-tolerance to maximize uptime. First, the PowerKeeper Performance Monitor continuously checks the internal Agents of the PowerKeeper unit. If an Agent fails, it is automatically restarted and a SNMP trap (if configured) can be sent to alert administrators. Secondly, PowerKeeper supports a high-availability (HA) pairing of two PowerKeeper units as a primary and replica server. When configured in a HA configuration, the primary PowerKeeper unit will send all data changes to the replica unit. The replica unit will continually monitor the status of the primary unit, and will automatically promote itself to primary if the primary is unavailable for a customer-defined interval. The failover can also happen manually if a unit needs to be taken off-line temporarily. Thirdly, the PowerKeeper unit can be configured to automatically write out encrypted backups to a remote machine. If there is a complete failure of both PowerKeeper units (or a single Pow
