Disaster Recovery Replication
Restoring critical business operations can be as simple as connecting to the SAN via an online connection, and switching over to the replicate server. Recovery is synchronizing back with the original server to restore it to its original state.
Popular storage replication solutions include:
- Dell EqualLogic™ Autoreplication enables asynchronous replication via an online connection. It supports up to 16 peer storage groups which can be grouped together and linked to a central site. The clone replica option clones the replica for independent storage, keeping the original replica intact. Bi-directional (reciprocal/replication) for branch reverse synchronization is also supported.
- Dell Compellent replication uses Remote Instant Replay leverages space-efficient snapshots between local and remote sites for cost-effective disaster recovery and business continuity.
- VMware Site Recovery Manager: this is suitable for small businesses and automates backup processes. Site Recovery Manager comes in two licenses: Standard (protects up to 75 VMs per site) and Enterprise (for more than 75 clients).
- EMC Celerra Replicator allows asynchronous snapshot-based data replication over IP networks. The software synchronizes online with the original data file, and only saves incremental changes offsite. It supports local, remote, one-to-many and cascading replication.
- RecoverPoint provides bi-directional synchronous replication, for both local and remote continuous data protection. RecoverPoint works best with EMC Replication Manager, but can also work with other products.
- HP Replication software uses Site Recovery Manager, and integrates it with HP Storage Arrays. The various HP replication solutions are based on the type of HP storage arrays in place.
