Protecting file data using snapshots

A snapshot of an entire file system or of an independent fileset can be created to preserve the contents of the file system or the independent fileset at a single point in time.

A fileset snapshot is a snapshot of the entire inode space. Any snapshot of an independent fileset also includes any dependent filesets contained within that independent fileset. You cannot create a snapshot of a dependent fileset. For more information on creating and maintaining snapshots, see Creating and maintaining snapshots of file systems.

Snapshots can be used in environments where multiple recovery points are necessary. Ensure that the file system is mounted before restoring the snapshot. For information about mounting a file system, see Mounting a file system. For information on restoring data by using snapshots, see Restoring a file system from a snapshot.
