TimeShift takes incremental snapshots of the file system at regular intervals. These snapshots can be restored later to bring your system to the exact state it was in at the time when the snapshot was taken.
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.
TimeShift is designed to protect only system files and settings. User files such as documents, pictures and music are excluded. This ensures that your files remains unchanged when you restore your system to an earlier date.
