Abstract
A technique for facilitating file system operations in a data storage system provides multiple version family databases. Each version family database identifies members of a respective version family, i.e., a respective set of files in a file system that are related by file snapping. When a snap of a file is created, the file system updates a version family database for the version family that includes the file, such that the version family database identifies both the file and the snap.
