Abstract:
One or more techniques and/or computing devices are provided for implementing resynchronization operations. For example, a disaster recovery relationship may be established between a source storage volume, hosted by a source storage node, and a destination storage volume hosted by a destination storage node, such that data is replicated from the source storage volume to the destination storage volume for disaster recovery purposes. If the disaster recovery relationship breaks, then new compliance data, locked down into a write once read many state, may be created at the destination storage volume. A resynchronization operation may be performed to reestablish the disaster recovery relationship, while preserving the new compliance data so that a compliance policy is not violated. For example, cloned storage volumes, copying compliance data to source storage volumes before resynchronization, and/or moving compliance data to local volumes may be used to implement resynchronization operations while preserving compliance data.
