Abstract
A method of replicating a deduplicated storage system is disclosed. The method comprises storing a stream of data on an originator deduplicating system by storing deduplicated segments and information on how to reconstruct the stream of data. The method further comprises replicating the originator deduplicating system by receiving a copy of the deduplicated segments, information regarding containers for the deduplicated segments, and information on how to reconstruct the stream of data transferred from the originator deduplicating system to the replica system.
Claims18
A system for replicating a deduplicated storage system comprising:
- an originator deduplicating system, wherein the originator deduplicating system stores a stream of data by storing deduplicated segments and information on how to reconstruct the stream of data on the originator deduplicating system;
- and
- a replica system replicating the originator deduplicating system, wherein the replica system receives a copy of the deduplicated segments, information regarding containers for the deduplicated segments, and information on how to reconstruct the stream of data transferred from the originator deduplicating system.
A method for replicating a deduplicated storage system comprising:
- storing a stream of data on an originator deduplicating system by storing deduplicated segments and information on how to reconstruct the stream of data;
- and
- replicating the originator deduplicating system by receiving a copy of the deduplicated segments, information regarding containers for the deduplicated segments, and information on how to reconstruct the stream of data transferred from the originator deduplicating system to the replica system.
A computer program product for replicating a deduplicated storage system, the computer program product being embodied in a computer readable medium and comprising computer instructions for:
- storing a stream of data on an originator deduplicating system by storing deduplicated segments and information on how to reconstruct the stream of data;
- and
- replicating the originator deduplicating system by receiving a copy of the deduplicated segments, information regarding containers for the deduplicated segments, and information on how to reconstruct the stream of data transferred from the originator deduplicating system to the replica system.
