ABC Investment Bank is implementing a security and disaster recovery plan. As part of the plan, it sets up several remote data centers across the globe. The objective was to not have all the records of any one important client at one location but to distribute chunks of it throughout these centers. This was so if any one of the centers is compromised, the attacker will not have only chunks of data and will not be able to use it maliciously against the bank’s clients. One other advantage of this is that if a center is struck by a disaster, all the data about a client’s portfolio is not lost. For this plan to work, a percentage of deviation should not exist between the actual and targeted business data. Which recovery metric best defines this percentage of deviation?
