-Local replication refers to replicating data within the same array or the same data center.
-Snapshot and volume copy/mirror capabilities
-In business-critical environments, users require strong protection for their valuable data sets. To help users protect data in the most efficient way, local replication leverages the power of Infortrend storage systems to provide snapshot and volume copy/mirror capabilities. With space-saving snapshot copies, users can easily restore files or rollback data as necessary. With the full data copies, users can quickly restore service when a RAID-protected volume fatally fails.
-Remote replication is the process of copying production data to a device at a remote location for data protection or disaster recovery purposes.
-Remote replication may be either synchronous or asynchronous. Synchronous replication writes data to the primary and secondary sites at the same time. With asynchronous replication, there is a delay before the data gets written to the secondary site. Because asynchronous replication is designed to work over longer distances and requires less bandwidth, it is often a better option for disaster recovery. However, asynchronous replication risks a loss of data during a system outage because data at the target device isn't synchronized with the source data.

The local replication resolution presents comfortable and cost-effective regional point-in-time data representations utilizing storage-based, and full-volume clones. It produces copies quicker and more commonly than host-based resolutions, with no influence on the generation of applications.
Remote replication is the method of copying composition data to a machine at a primitive location for data assurance or accident restoration objectives. Remote replication may be either simultaneous or asynchronous. Simultaneous replication communicates data to the primitive and subsidiary positions at the identical time.
