Abstract
A system and method for automatic disaster recovery of a computing appliance including reconstruction of its previous operational state. A configuration bundle that includes configuration data, software revision level and a list of system updates is used to recover the device's operation state. The system and method can also be utilized to recover a not fully functional member of a clustered computing system from the configuration information stored on other members of the cluster.
Claims20
A method for recovering a computing appliance to a previous operational state after a failure, comprising:
- creating a disaster recovery medium, wherein the disaster recovery medium includes:
- a configuration bundle, wherein the configuration bundle includes;
- a system database;
- meta data associated with the computing appliance;
- and
- one or more configuration files;
- and
- one or more software packages installed on the computing appliance;
- running, automatically upon detecting connection of the disaster recovery medium to the computing appliance;
- an initialization program on the computing appliance to reach a first operational state;
- accessing the disaster recovery medium from the computing appliance, wherein accessing includes reading portions of the database, the metadata and the configuration files and storing the portions read to a storage medium on the computing appliance;
- installing the software packages on the computing appliance to reach a second operational state, wherein installing includes reading, by the computing appliance, the software packages from the disaster recovery medium;
- and
- applying, from within the computing appliance, portions of the configuration bundle stored on the computing appliance to restore the computing appliance to the previous operational state.

A system, comprising:
- a computing appliance;
- a disaster recovery medium connected to the computing appliance, wherein the disaster recovery medium includes:
- a configuration bundle, wherein the configuration bundle includes:
- a system database;
- meta data associatedwith the computing appliance;
- and
- one or more configuration files associated with the computing appliance;
- and
- one or more software packages;
- wherein the computing appliance automatically accesses the disaster recovery medium upon detecting connection of the disaster recovery medium to the computing appliance, wherein the accessing includes:
- running an initialization program stored on the disaster recovery medium to reach a first operational state;
- reading portions of the database, the metadata and the configuration files and storing the portions read to a storage medium on the computing appliance;
- installing the software packages on the computing appliance to reach a second operational state, wherein installing includes reading, by the computing appliance, the software packages from the disaster recovery medium;
- and
- applying, from within the computing appliance, portions of the configuration bundle stored on the computing appliance to restore the computing appliance to the previous operational state.
