Abstract

A distributed and deduplicating file system that stores backup metadata to object storage is described. A node, in a cluster of nodes, receives backup data associated with a write operation to back up a data file, and identifies metadata associated with deduplicated data by deduplicating the backup data. If the access frequency associated with the metadata is greater than or equal to an access threshold, and the size of the metadata is less than or equal to a storage threshold, the cluster writes the metadata to each of the memory devices corresponding to the nodes in the cluster. If the access frequency associated with the metadata is less than the access threshold, or the size of the metadata is more than the storage threshold, the node writes information which includes the metadata to an object storage that stores data objects for the nodes in the cluster.
