Abstract: To leverage the attributes of object storage for applications/systems created to interface with a network files system, an object storage backed file system can accept the defined file system commands from the applications/systems and transform the file system commands into requests that target object storage. The file system is “backed” by object storage because attributes and content of file system entities are stored in objects. For instance, content data and metadata of a file are stored in objects in object storage. This object storage backed file system can be considered a bridge between a client perceived hierarchical file system namespace and a flat namespace of an object storage.

Abstract: To effectively implement ILM policies and account for unreliability in a geographically distributed large-scale storage system, “scanners” and “ILM rules appliers” can be deployed on nodes throughout the storage system for large scale ILM implementation. Each scanner is programmed to deterministically self-assign a region of object namespace and scan that region of object namespace. To “scan” a region, a scanner accesses metadata of each object that has an identifier within the scanner's region and inserts the object metadata into one of a set of queues for ILM evaluation. An ILM rules applier dequeues object metadata for evaluation against ILM rules and determines whether an ILM task is to be performed for ILM rule compliance.
