Techniques are provided for directory snapshot and data management. Conventional snapshot functionality creates snapshots at a volume level. Volume level snapshots are inadequate for scale-out storage architectures because a single volume snapshot of a shared storage resource may not satisfy different data protection requirements of clients using the shared storage resource. The disclosed techniques are capable of creating snapshots at a directory level. The directory level snapshots are created and maintained using an inode identity map to track active inode numbers of directory files that have diverged. Snapshot generation numbers are used to determine whether a file is part of a directory for which snapshotting is enabled. A version map used to track versions of a file modified across different directory snapshots and an active file system. A delayed free metafile is used to determine whether file block numbers of a directory can be freed.
