Designing Backup to Replace Primary Storage
Users and application owners expect that the systems they use will never go down, and if they do they will be returned to operation quickly with little data loss. In our article “Designing Primary Storage to Ease the Backup Burden” we discussed how to architect a primary storage infrastructure that is able to help meet these challenges. We call this design Protected Primary Storage. But this design can be expensive, especially if it is applied to every application in the data center. For data centers that are not at the point of a storage refresh, or simply not able to afford that type of commitment, another design is required; Protected Storage as Standby. This design is less expensive but has longer yet still acceptable recovery point objectives (RPO) and recovery time objectives (RTO).
