Abstract
A method and system for backing up and restoring data of production servers. A mapping that maps volumes of production servers to volumes of a data protection server is maintained on the data protection server. When volumes of the data protection server are backed up, the mapping may be stored on the archive media together with the data of the volumes. Later, during a restore, the mapping is read from the archive media. The mapping allows the data to be restored to the data protection server or directly to the production servers.
Claims20
A computer-readable medium having computer-executable instructions, comprising:
- maintaining a mapping that maps a first volume of a first computer to a second volume of a second computer, wherein the second volume stores a copy of data of the first volume, wherein the copy is updated as the data of the first volume is updated;
- and
- backing up data of the second volume in a storage library together with the mapping.
A method for backing up and restoring data, comprising:
- creating a shadow copy of a second volume of a second computer, wherein the second volume of the second computer stores a copy of data of a first volume of a first computer;
- and
- backing up the shadow copy to storage media.
A system for backing up and restoring data, comprising:
- a writer arranged to create a crash consistent state of data for an application associated with the writer, wherein the writer is also arranged to maintain mappings between remote volumes and local volumes;
- a service arranged to coordinate creating a shadow copy of a volume including the data by communicating with the writer;
- and
- a requester arranged to query the writer to discover the local volumes and to make a backup of the local volumes together with information including the mappings.
