Disaster Recovery by Remote Location Backup Remote Copy using Fibre Channel Interface (Remote Advanced Copy function (REC))

REC (Remote Equivalent Copy) provides a server-less remote mirroring function which ensures fast recovery when the primary site ETERNUS AF/ETERNUS DX become unusable because of a disaster, such as fire, earthquake or malicious damage.

Remote Advanced Copy for Storage Area Network (SAN)

By using Fibre Channel interfaces, Remote Advanced Copy can provide lower cost remote site support between a primary storage device and a secondary device.

Extended Remote Advanced Copy for Wide Area Network (WAN)

Extended Remote Advanced Copy uses a combination of a Fibre Channel switch and WAN converter to support very long distances over WAN. Replicated data can be located at a remote site hundreds of kilometers away from the primary site. This provides high security for the protection of critical data from both man-made and natural disasters.

In addition, ETERNUS AF or ETERNUS DX S2 and later support replication between common models and newer/previous models, as well as N to 1 integrated backup. These capabilities enable flexible system configuration matched to requirements.
