Abstract
A method, non-transitory computer readable medium and programmed apparatus that receives a request to replicate a volume from a source to a destination. The volume includes data and metadata including information descriptive of the data. The method includes determining a first set of blocks and a second set of blocks associated with the source, where the first set of blocks is associated with the metadata, and where the second set of blocks is associated with the data. The method includes initiating, based on the first set of blocks, replication of the volume from the source to the destination to generate a replicated volume at the destination. The replicated volume includes replicated metadata generated based on the replicated first set of blocks and includes absent allocated data corresponding to the data included in the volume storage at the source storage system.
