Disaster recovery for a storage system is provided. A data record is generated for a primary computing system that identifies a secondary computing system and indicates a first storage device that includes block storage and a second storage device that includes object storage. The primary computing system experiences either a migration or a failover. Storage space is provisioned in block storage and object storage. Data records from the primary computing device are respectively stored in either the block storage or the object storage based on their respective access rates. Data records that are stored as block storage entries are predicted to have a higher access rates than data records that are stored as object storage entries.
