Techniques are provided for performing a storage operation targeting objects stored across multiple storage tiers of a cloud storage environment. A volume may be backed up as objects stored across the multiple storage tiers of the cloud storage environment, such as a standard storage tier directly accessible to the storage operation, an archival storage tier not directly accessible to the storage operation, etc. The storage operation may target the objects, such as where the storage operation is a directory restore operation to restore a directory of the volume. The storage operation can be successfully implemented such as to restore the directory even though objects of the storage operation are stored across the multiple storage tiers of the cloud storage environment.

Granular cloud restore with multi storage class support

Techniques are provided for tiering snapshots to archival storage in remote object stores. A restore time metric, indicating that objects comprising snapshot data of snapshots created within a threshold timespan are to be available within a storage tier of a remote object store for performing restore operations, may be identified. A scanner may be executed to evaluate snapshots using the restore time metric to identify a set of candidate snapshots for archival from the storage tier to an archival storage tier of the remote object store. For each candidate snapshot within the set of candidate snapshots, the scanner may evaluate metadata associated with the candidate snapshot to identity one or more objects eligible for archival from the storage tier to the archival storage tier, and may archive the one or more objects from the storage tier to the archival storage tier.

Flexible tiering of snapshots to archival storage in remote object stores

Techniques are provided for restoring a directory from a snapshot of a volume backed up to an object store. The snapshot may be backed up from a node to the object store, such as a cloud computing environment. A user may want to restore the directory within the volume without having to restore the entire volume, which otherwise would waste computing resources, storage, network bandwidth, and time. Accordingly, the techniques provided herein are capable of restoring just the directory from the snapshot that is stored within the object store. Because snapshot data of the snapshot may be stored across multiple objects within the object store, certain objects are identified as comprising snapshot data (backup data) of the directory and content items within the directory. In this way, the snapshot data of the directory is restored from these objects to a restore directory at a restore target.
