+Timeshift for Linux is an application that provides functionality
+similar to the System Restore feature in Windows and the Time Machine
+tool in Mac OS. Timeshift protects your system by taking incremental
+snapshots of the file system at regular intervals. These snapshots
+can be restored at a later date to undo all changes to the system.
+
+In RSYNC mode, snapshots are taken using rsync and hard-links.
+Common files are shared between snapshots which saves disk space.
+Each snapshot is a full system backup that can be browsed with a
+file manager.
+
+In BTRFS mode, snapshots are taken using the in-built features
+of the BTRFS filesystem. BTRFS snapshots are supported only on
+BTRFS systems having an Ubuntu-type subvolume layout
+(with @ and @home subvolumes).
