  • Patent number: 8924589
    Abstract: High availability architecture that employs a mid-tier proxy server to route client communications to active data store instances in response to failover and switchover. The proxy server includes an active manager client that interfaces to an active manager in each of the backend servers. State information and configuration information are maintained separately and according to semantics consistent with needs of corresponding data, the configuration information changing less frequently and more available, the state information changing more frequently and less available. The active manager indicates to the proxy server which of the data storage instances is the currently the active instance. In the event that the currently active instance is inactive, the proxy server selects a different backend server that currently hosts the active data store instance. Client communications are then routed to the different backend server with minimal or no interruption to the client.

  • Publication number: 20060206544
    Abstract: An automatic database backup and restoration system comprises an interface component that receives statements relating to backing up at least a portion of a first database, the original database resident upon a consumer computing device. A backup component associated with the interface component automatically copies at least the portion of the first database and writes the copied portion to a backup database, the backup database is a full backup of the first database. The consumer computing device can be, for example, one of a laptop computer, a desktop computer, a personal digital assistant, and a cellular phone.
