Abstract
A system and method for providing access to replicated data is disclosed. Embodiments of the present invention utilize a remote access file system to provide access to replicated data concurrently with replication. According to one embodiment including unidirectional replication, access to a replicated target volume is provided using a remote access file system to perform reads locally or “directly” and to perform writes indirectly to a replication source volume which are subsequently replicated to the replication target volume. According to another embodiment, bidirectional replication is provided and access to both replication source and replication target volumes are provided locally and subsequently replicated as necessary.
