Multi-RPO data protection

摘要

A system for disaster recovery including a controller (i) for controlling bandwidth usage of a disaster recovery system in accordance with a plurality of recovery point objectives (RPOs), each RPO designating a maximal time loss constraint for data recovery for an enterprise production system, and a corresponding bandwidth allocation for the disaster recovery system to use in replicating data for the enterprise production system, wherein the RPOs are applied in accordance with a calendar-based schedule of dates and times, and (ii) for issuing an RPO alert when the RPO maximal time loss constraint for a current date and time is not satisfied.

1. A system for disaster recovery, comprising:
a controller for a server having at least one processor, the controller having a virtual manager configured to cause the at least one processor to manage at least one hypervisor and to cause the at least one processor to:
(i) control bandwidth usage of a disaster recovery system in accordance with a plurality of recovery point objectives (RPOs), each of the plurality of RPOs designating a maximal time loss constraint for data recovery for an enterprise production system, wherein the enterprise production system includes a hypervisor system comprising multiple virtual protection groups, and a corresponding bandwidth allocation for the disaster recovery system to use in replicating data for the enterprise production system, wherein each of the plurality of RPOs are applied in accordance with a calendar-based schedule of dates and times, wherein multiple calendar-based schedules are used to schedule each of the RPOs and bandwidth allocations to control issuance of RPO alerts and the bandwidth usage for data replication for a corresponding virtual protection group of the enterprise production system, and(ii) issue an RPO alert when the maximal time loss constraint for a current date and time for one of the plurality of RPOs is not satisfied when the maximal time loss constraint exceeds a bandwidth constraint.
