A wide spectrum of replication solutions exist for deployment in storage networks and data centers, trading off RPO, RTO and cost against each other. An analysis of the different major modes of replication, along with their various merits and problem solving approaches, was presented here to highlight the suitability of each.

Whether operating on an IP-SAN or NAS StorTrends storage device, data replication in StorTrends iTX software contains all three of the primary replication modes (synchronous, asynchronous, and snapshot-assisted) discussed in this paper. StorTrends iTX also offers a form of mirroring in its high availability configuration. This flexibility makes it equally effective for units installed in remote offices as it is for units installed in the same rack in the data center.
