Asynchronous Remote Replication (Disaster Recovery)

Protect Your Data, At Any Distance

The day may come when all efforts to safeguard data at the production site has failed. Every minute of downtime could mean 10’s or 100’s thousands of dollars of lost revenue, and even worse, a damaged industry reputation. With asynchronous remote replication, the data is duplicated and becomes quickly accessible in the event that the production site becomes unavailable. Asynchronous mirroring provides the highest integrity and the most flexible disaster recovery service for all applications and business critical data.

Asynchronous remote replication copies all protected production volumes to the remote site where it can be used for disaster recovery

The data is safe at the remote site, now what? Many companies go this far, but fail to take the next critical step in their DR plan: Testing. With asynchronous remote replication, non-disruptive tests can be conducted against the production data and applications as often as needed. Simply engage test mode for any volume at the remote site and the remote application servers are presented with the latest copy of the production volume. When the test is complete, simply disengage test mode and the state of the system reverts back, with no impact on production.

There are various solutions available to replicate data to a remote site, that part is easy. But what if a fail-over and then a subsequent fail-back become necessary? This is much more difficult. The Advanced Site Recovery feature automatically reverses the asynchronous replication direction during a fail-over or fail-back operation to ensure that the alternate site receives all updates once services are restored. And, unlike other solutions, a full resynchronization of all the data is not necessary to bring the original site back on-line. This saves time, money, and a lot of frustration, not to mention prevents unnecessary downtime during the transition.
