Abstract: A technique enables recovery of failover data used to generate one or more High Frequency Snapshots (HFSs) at a source and replicated to a target for storage and recovery. The target is illustratively an intermediary repository embodied as a long-term storage service (LTSS) configured to organize and store the HFSs as recovery points (RPs) in an object store. The LTSS stores a HFS identifier (ID), a logical offset in an object of the object store storing data of the HFS, and a logical timestamp associated with each replicated HFS as a key of a segment descriptor in a key-value database configured to store metadata describing the failover data of the HFS stored as one or more objects in the object store. Upon recovery of the failover data, the technique enables identification of the HFS stored in the object store and creation of a HFS index metadata structure (B+ tree) to extract the identified HFS as a RP.
