Abstract
A method for disaster recovery for distributed storage is provided. The method includes distributing erasure coded data to N storage systems at N sites so that the data is recoverable from N−1 storage systems at N−1 sites in case of failure of one of the N storage systems. The method includes coordinating movement of one or more storage devices of a replacement storage system to each of the N−1 sites and transferring data for rebuilding the erasure coded data, from each of the N−1 storage systems to the one or more storage devices of the replacement storage system, responsive to the failure of the one of the N storage systems. The method includes coordinating movement of the one or more storage devices of the replacement storage system to the one of the N sites or a further replacement site, to restore recoverability of the distributed archival storage.
