Abstract: The present disclosure is generally related to replicating metadata. A method includes accessing a first file with a first unique identifier at a source location in a storage device, wherein metadata corresponding to the first file is stored in a first database with the first unique identifier. The method includes replicating the first file to produce a second file at a target location, wherein the second file has a second unique identifier. The method includes replicating the metadata and the first unique identifier to a second database. The method includes mapping the second unique identifier to the first unique identifier in the second database.

Abstract: Examples described herein include receiving a request for a clone of a directory tree in a distributed file system for the directory tree at a first point in time. Examples described herein also include generating a copy of an inode data and determining a relevancy of the clone based on a birth epoch and a death epoch of a first entry in the inode data. The inode data may describe a root of the directory tree at a second point in time.
