Remote Replication
Provides excellent solutions for disaster recovery, data backup or migration over a long distance

Remote Replication

Overview:

Remote replication is an essential part of data protection, providing protection in case of primary site failure. Remote replication provides a continuous, non-disruptive, host-independent solution for disaster recovery, data backup or migration over a long distance. Users concerned about budget, performance impact and data availability can flexibly choose to deploy synchronous or asynchronous replication.

Remote replication leverages the power of storage systems to copy data between storage pools or systems in IP or FC SAN at different sites. When source data fails due to system malfunction or accidents, users can leverage the disk-based remote copy to restart service in minutes. If users would like to transfer responsibility back to the source, it can be quickly synced with the remote copy for only differentials. To further ensure the integrity of the remote data, remote replication allows users to protect the remote copy with snapshot technology. Granular snapshot images can help restore the corrupt remote copy in seconds when it is required to resume business service.

Benefits:

Features Benefits
Minimized unplanned downtime Reduce recovery time after system failures; intact data copies at remote sites can be immediately used to support applications
Flexible data copy deployment Synchronous and asynchronous options for IP and FC SAN; users can split and re-sync the mirroring between source and copy as needed and take snapshots for remote data to enhance protection
Affordable data protection Achieve enterprise-class protection at affordable price points; companies with tight budgets do not need to compromise on data protection
Data compression Leverage data compression for asynchronous remote replication for increased efficiency
