High Availability and Disaster Recovery

Use Case – High Availability and Disaster Recovery

EVNearSync can be used for both high availability and disaster recovery to provide the best options to suit Enterprise Vault Continuity.

Unlike other solutions for Enterprise Vault high availability or Disaster Recovery EVnearSync does not require specialized hardware or software to be deployed. It does not require storage sub-sytems to be matched across local and remote sites and it does not require virtualization.

In the event of an outage users of Enterprise Vault can be switched to a secondary copy of the archive either locally or remotely. Because of the way EVNearSynch replication works with the Enterprise Vault safety copy mechanism there is zero potential for data loss, so an RPO of zero is delivered. Additionally if automated switchover is configured the RTO is a matter of seconds.
