Abstract
Replication techniques for file-based replication. A first file pool and a second pool may be created, respectively, on a first site and a second site. Storage for the first file pool may be provisioned from a first storage device group configured as a first consistency group. Storage for the second file pool may be provisioned from a second storage device group configured as a second consistency group. Modification operations, such as writes, may be applied to the first file pool. The modifications performed on the first file pool result in corresponding modifications to the first consistency group. The modifications may be replicated on the second file pool by applying the modifications to the second consistency group. File systems created in the first and second file pools may be self-contained and modifications applied to the first and second consistency groups may be applied in a specified order to ensure write consistency.
