Abstract:
1. A method for replicating deduplicated data, comprising: assigning a global block identifier to each of a plurality of blocks of deduplicated data in a source repository, wherein: transmitting a plurality of global block identifiers from the source repository to a target repository, wherein said transmitting comprises adding a value to each additional ID portion such that both the block ID portion and each additional ID portion comprises a value when each global block identifier is transmitted from the source repository to the target repository; determining whether each global block identifier is associated with an existing block of the deduplicated data located within the target repository; partitioning the plurality of global block identifiers into a first portion of global block identifiers previously existing within the target repository and a second portion of global block identifiers previously non-existing within the target repository based on the determination; transmitting, by the target repository, the first portion of global block identifiers back to the source repository; and transmitting, by the source repository, data from each block of deduplicated data associated with the first portion of global block identifiers to the target repository in response to receipt of the first portion of the global block identifiers.
