Abstract
Various embodiments illustrated and described herein include systems, methods, and computer program products to protect NTFS deduplicated volumes. Some embodiments select a data protection mode from various modes to protect deduplicated volumes. Some data protection modes retrieve the deduplicated files and associated data chunks without rehydrating the files and send them to a replica. Some data protection modes rehydrate deduplicated files as they are retrieved, send the rehydrated files to the replica, and turn on deduplication at the replica so the files can be deduplicated on the replica. Deduplication settings can also be transferred to the replica so that deduplication on the replica mimics deduplication on the source. Some data protection modes replicate the deduplicated files to the replica.
