312-76V3: EC-Council Disaster Recovery Professional (EDRP)

ABC Investment Bank is implementing a security and disaster-recovery plan. As part of this plan, it establishes several remote data centers worldwide. The goal is to avoid keeping all records for any important client in one location, instead distributing portions of those records among the centers. This ensures that, if one center is compromised, an attacker has only chunks of the data and cannot use it maliciously against the bank’s clients. Another benefit is that, if a center is affected by a disaster, all data about a client’s portfolio is not lost.

For this plan to work, no percentage deviation should exist between the actual and targeted business data. Which recovery metric best defines this percentage of deviation?
