    Abstract: Some examples described herein relate to implementing file level snapshots in a file system. In an example, a file may be selected for generating a snapshot file of the file. A determination may be made whether the snapshot file to be generated is a first snapshot of the file. If the snapshot file to be generated is the first snapshot of the file, a master snapshot file of the file may be created, and block-map table from the file may be copied to the master snapshot file. A snapshot file may be generated, and block-map table, both in the file and the snapshot file, may be replaced with an offset-map table.

    Abstract: Some examples described herein relate to performing a consistency check on namespace of an online file system. In an example, an inode table may be selected from an online file system. A directory inode may be selected in the inode table, and a consistency check may be performed on a dentry of a directory that maps to the selected directory inode. In response to identifying an inconsistency with the dentry, consequent to the consistency check, the dentry may be recorded in a database.
