Abstract: Techniques manage extents in a storage system having storage devices supporting a redundant storage strategy. A reserved area of the storage system is generated based on a set of first-type reserved extents respectively located in the storage devices, and the set of first-type reserved extents supports a reconstruction operation for a failed storage device when the failed storage device appears in the storage devices. A data area is generated based on a set of data extents respectively located outside the reserved area in the storage devices, and the data area provides data storage for a user. Here, a reserved extent size of the set of first-type reserved extents is smaller than a data extent size of data extents in the data area of the set of data extents. The quantity of extents can be reduced, thereby reducing overhead of storage and computing resources involved by associated metadata.

Abstract: A method for secure data synchronization and sharing between distinct cloud environments is disclosed. The method involves establishing a trust relationship between a data provider's private cloud deployment and a data consumer's public cloud deployment. Utilizing hardware processors, a cross-region group sharing token is generated and validated to facilitate secure communication and data traffic between the two cloud deployments. Upon validation, a firewall policy that previously restricted data exchange is disabled, allowing for the replication of a target database from the private cloud to a secure share area accessible by the public cloud deployment. The data consumer is then enabled to access and utilize the replicated database within this secure area. The method ensures consistent data management across both deployments by managing the synchronization of the replicated database with the data provider's original database, thereby maintaining data consistency and integrity.
