Timeshift
GPL-3.0Timeshift protects Linux operating systems with BTRFS and rsync snapshots, offering quick rollbacks after bad updates while leaving personal files intact.

Overview
Tony George built Timeshift in 2014 to bring automated system rollback capabilities to Linux workstations. The Linux Mint project adopted the utility under its XApp initiative in 2022 to ensure long-term maintenance across desktop environments. Today, it operates as an operating system restore engine that freezes system state while leaving personal files untouched.
Why Timeshift instead of Apple Time Machine
Apple Time Machine integrates into macOS to back up operating system files and user documents together in one unified stream. Timeshift separates these concerns on Linux by snapshotting only the root filesystem and excluding /home by default. Rolling back a broken kernel, graphics driver regression, or failed package upgrade leaves active Git repositories, local containers, and project directories untouched.
Storage integration also differs. Time Machine supports networked storage pools, while Timeshift targets local partitions and rejects network shares like NFS or Samba to prevent permission corruption during emergency restores. Timeshift interfaces directly with Linux storage layers, offering copy-on-write snapshots on BTRFS subvolumes alongside rsync with hard links on ext4. Boot integration relies on GRUB2 and /etc/timeshift/restore-hooks.d scripts, supporting live rollbacks from a running desktop or offline restoration via live USB media.
What it does well
- Sub-second BTRFS snapshots: Takes instant copy-on-write snapshots on
@root subvolumes, letting developers freeze system state before risky package updates without file-copying overhead. - Scriptable CLI: Exposes full snapshot creation, listing, and restoration through the command line, enabling DevOps engineers to automate rollback checkpoints inside deployment scripts and cron schedules.
- Lifecycle hook scripts: Executes custom shell scripts in
/etc/timeshift/backup-hooks.dand/etc/timeshift/restore-hooks.d, automating validation checks and partition syncs prior to rebooting. - Non-destructive workspace protection: Restricts rollbacks to system files, ensuring active Git branches and build artifacts in user directories remain safe during restores.
- Bootloader recovery integration: Coordinates with GRUB2 and live Linux environments, offering a reliable path to restore unbootable machines without reinstalling the operating system.
