Linux filesystem snapshot management tool

 Snapper is a tool for Linux filesystem snapshot management. Apart from the

 differences between snapshots. In simple terms, this allows root and non-root
 users to view older versions of files and revert changes.
 The features include:
   * Manually create snapshots
   * Automatically create snapshots, e.g. when using a package manager
   * Automatically create timeline of snapshots
   * Show and revert changes between snapshots
   * Works with btrfs and thin-provisioned LVM volumes
   * Supports Access Control Lists and Extended Attributes
   * Automatic cleanup of old snapshots
   * Command line interface
   * D-Bus interface
   * PAM module to create snapshots during login and logout (libpam-snapper)
