Abstract: A group of state data of storage space in a storage system is collected according to a predetermined time interval, the group of state data being collected at a group of time points, respectively, and the group of time points being divided according to the predetermined time interval. The group of state data is compared with a threshold condition of the storage system, the threshold condition representing that storage space in the storage system is to be exhausted. An association relationship between a state of storage space in the storage system and a future time point is generated based on the group of state data in accordance with determining at least one state data in the group of state data satisfies the threshold condition. A state estimate of storage space in the storage system at a specified future time point is obtained based on the generated association relationship.

Abstract: Techniques for the increased efficiency of storing data objects storage in the object storage of a software designed data center (SDDC) are provided. The techniques include the efficient storage of data, while enabling snapshots of each updating of the data. The snapshots of the data may be efficiently recovered via the techniques. Difference-level mappings for each snapshot are encoded in compact self-balancing data trees included in the object's metadata. The metadata mappings include mappings between various address spaces employed by the SDDC, as well as the address spaces employed by data stores that store the data on physical medium. Because the metadata is efficiently structured, the metadata for an object may be cached for quick lookups during data access and/or snapshot recovery. The techniques also provide low-latency recovery and/or system rollback in the event of any failure in the SDDC.
