Linux filesystem snapshot management tool

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, ext4 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)
