Improving VMware Disaster Recovery with EMC RecoverPoint

RecoverPoint provides a full-featured replication and continuous data protection

solution for VMware ESX servers. For remote replication, it utilizes synchronous

replication with a zero recovery point objective (RPO), or asynchronous replication

with a small RPO. This enables RecoverPoint to protect the VMware ESX platform from

data corruption and guarantees recoverability with little to no data loss. For local

protection, it preserves every write, allowing data recovery to any point in time.

RecoverPoint CDP, CRR, and CLR

EMC RecoverPoint provides local and remote replication. Local replication of a LUN is

provided through the EMC RecoverPoint continuous data protection (CDP) capability

and remote replication of a LUN is provided though the RecoverPoint continuous

remote replication (CRR) capability. Additionally the same LUNs can be protected

locally and remotely. This capability is called continuous local and remote (CLR) data

protection.

The innovative technology of RecoverPoint supports flexible levels of protection

without distance limitations or performance degradation. RecoverPoint’s technology

offers a fine-grain recovery of application data and reduces the recovery point to zero.

Users can recover their data to any point in time, eliminating the need to invest in

physical recovery of data damaged because of server outages, data corruption,

software errors, viruses, or common user errors.

All of these capabilities help the customer achieve a dramatically lower total cost of

ownership (TCO) compared to other host- or array-based replication solutions.

Recovery testing is also made easier because of the ability to access the replicated

data at the local or remote site for recovery or integrity testing purposes without

interrupting the replication or the ongoing data center operations.
