A distribution plan that indicates how to encode and distribute backup data across multiple data centres may be generated. The distribution plan may be generated such that one or more characteristics of the distribution plan, such as costs, are optimized while constraints on the plan, such as protection level, recovery point objective (RPO), and recovery time objective (RTO) are satisfied. The protection level may indicate the number of the data centres that are to remain available such that the backup data is recoverable from encoded fragments of the backup data stored in the data centres that remain available. |
