System restore utility for Linux

Project page: https://github.com/teejee2008/timeshift

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).

Timeshift is similar to applications like rsnapshotBackInTime and TimeVault but with different goals. It 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. If you need a tool to backup your documents and files please take a look at the excellent BackInTime application which is more configurable and provides options for saving user files.


Minimal Setup

  • Timeshift requires very little setup. Just install it, run it for the first time and take the first snapshot. Cron job can be enabled for taking automatic snapshots of the system at regular intervals. The backup levels can be selected from the Settings window.
  • Snapshots are saved by default on the system (root) partition in path /timeshift. Other linux partitions can also be selected. For best results the snapshots should be saved to an external (non-system) partition.

Multiple Snapshot Levels

  • Multiple levels of snapshots can be enabled – Hourly, Daily, Weekly, Monthly and Boot
  • Number of snapshots to retain can be specified for each level
  • Boot snapshots provide an additional level of backup and are created every time the system starts. Boot snapshots are created with a delay of 10 mins so that system startup is not affected.

Rsync & BTRFS Snapshots

  • Supports rsync snapshots on all systems
  • Supports BTRFS snapshots on BTRFS systems

It is strongly recommended to use BTRFS snapshots on systems that are installed on BTRFS partition. BTRFS snapshots are perfect byte-for-byte copies of the system. Nothing is excluded. BTRFS snapshots can be created and restored in seconds, and have very low overhead in terms of disk space.

User Data is Excluded by Default

Timeshift is designed to protect system files and settings. It is NOT a backup tool and is not meant to protect user data. Entire contents of users’ home directories are excluded by default. This has two advantages:

  • You don’t need to worry about your documents getting overwritten when you restore a previous snapshot to recover the system.
  • Your music and video collection in your home directory will not waste space on the backup device.

You can selectively include items for backup from the Settings window. Selecting the option “Include hidden items” from the Users tab will backup and restore the .hidden files and directories in your home folder. These folders contain user-specific config files and can be included in snapshots if required.

Note: It is not recommended to include user data in backups as it will be overwritten when you restore the snapshot.

Better Snapshots & Rotation

  • Unlike similar tools that are scheduled to take backups at a fixed time of the day, Timeshift is designed to run once every hour and take snapshots only when a snapshot is due. This is more suitable for desktop users who keep their laptops and desktops switched on for few hours daily. Scheduling snapshots at a fixed time on such users will result in missed backups since the system may not be running when the snapshot is scheduled to run. By running once every hour and creating snapshots when due, Timeshift ensures that backups are not missed.
  • Applications like rsnapshot rotate a snapshot to the next level by creating a hard-linked copy. Creating a hard-linked copy may seem like a good idea but it is still a waste of disk space, since only files can be hard-linked and not directories. The duplicated directory structure can take up as much as 100 MB of space. Timeshift avoids this wastage by using tags for maintaining backup levels. Each snapshot will have only one copy on disk and is tagged as “daily”, “monthly”, etc. The snapshot location will have a set of folders for each backup level (“Monthly”, “Daily”, etc) with symbolic links pointing to the actual snapshots tagged with the level.

System Restore

  • Snapshots can be restored by selecting a snapshot from the main window and clicking Restore button on the toolbar.
  • Snapshots can be restored either from the running system (online restore) or from another system that has Timeshift installed on it (offline restore).
  • If the main system is not bootable, then it is possible to boot from an Ubuntu Live CD, install Timeshift on the live system, and restore a snapshot on the main system.
  • Restoring backups from the running system requires a reboot to complete the restore process.

Cross-Distribution Restore

  • You can also Timeshift across distributions. Let’s say you are currently using Xubuntu and decide to try out Linux Mint. You install Linux Mint on your system and try it out for a week before deciding to go back to Xubuntu. Using Timeshift you can simply restore the last week’s snapshot to get your Xubuntu system back. Timeshift will take care of things like reinstalling the bootloader and other details.
  • Since installing a new linux distribution also formats your root partition you need to save your snapshots on a separate linux partition for this to work.
  • It is recommended to include hidden items in home directory by selecting the option “Include Hidden Items” from SettingsUsers.

Supported System Configurations

  • Normal – OS installed on non-encrypted partitions
  • LUKS Encrypted – OS installed on LUKS-encrypted partitions
  • LVM2 – OS installed on LVM2 volumes (with or without LUKS)
  • BTRFS – OS installed on BTRFS volumes (with or without LUKS)
    • Only Ubuntu-type layouts with @ and @home subvolumes are supported
    • @ and @home subvolumes may be on same or different BTRFS volumes
    • @ may be on BTRFS volume and /home may be mounted on non-BTRFS partition
    • Other layouts are not supported
  • GRUB2 – Bootloader must be GRUB2. GRUB legacy and other bootloaders are not supported.
  • EFI – EFI systems are supported. Make sure that /boot/efi partition is selected for mounting before restoring snapshots (application will do it automatically).
  • Encrypted Home – For users with encrypted home, files in /home/.ecryptfs/$USER will be backed-up and restored. The decrypted contents in $HOME will be excluded. This avoids the security risk of decrypted contents becoming available outside the user’s home directory.
  • Encrypted Private Directory – For users with encrypted Private directory, the encrypted files in $HOME/.Private, as well as the decrypted files in $HOME/Private, will be excluded (as it contains user data). Filters added by user to include files from $HOME/.Private or $HOME/Private will be ignored.
  • Docker & Containers – Docker and containerized systems are not supported. Running Timeshift on such systems will have unpredictable results.


Ubuntu-based Distributions

Ubuntu, Linux Mint, Elementary OS, etc.

Packages are available in the Launchpad PPA for supported Ubuntu releases. Run the following commands in a terminal window:

sudo add-apt-repository -y ppa:teejee2008/ppa
sudo apt-get update
sudo apt-get install timeshift

DEB and RUN packages are available on Releases page for older Ubuntu releases which have reached end-of-life.

Other Linux Distributions

Download the installer from Releases page and execute it in a terminal window:

# 64-bit
sudo sh ./timeshift*amd64.run

# 32-bit
sudo sh ./timeshift*i386.run  

Installer can be used on the following distribution types:

  • Fedora based – Fedora, RedHat, Cent OS, etc (supports dnf and yum)
  • Debian based – Debian, Ubuntu, Linux Mint, Elementary OS, etc (supports apt)
  • Arch based – Arch Linux, Manjaro, etc (supports pacman)


Run the following command in a terminal window:

sudo apt-get remove timeshift

Remember to delete all snapshots before uninstalling. Otherwise the snapshots continue to occupy space on your system. To delete all snapshots, run the application, select all snapshots from the list (CTRL+A) and click the Delete button on the toolbar. This will delete all snapshots and remove the /timeshift folder in the root directory.

If you used the installer to install Timeshift, you can remove the installed files with following command:

sudo timeshift-uninstall

Known Issues & Limitations

BTRFS volumes

BTRFS volumes must have an Ubuntu-type layout with @ and @home subvolumes. Other layouts are not supported. Systems having the @ subvolume and having /home on a non-BTRFS partition are also supported.

Disk Space

Timeshift requires a lot of disk space to keep snapshot data. The device selected as snapshot device must have sufficient free space to store the snapshots that will be created.

If the backup device is running out of space, try the following steps:

  • Reduce the number of backup levels – Uncheck the backup levels and keep only one selected
  • Reduce the number of snapshots that are kept – In the Schedule tab set the number of snapshots to 5 or less.
  • You can also disable scheduled snapshots completely and create snapshots manually when required

Bootloader & EFI

  • Only those systems are supported which use GRUB2 bootloader. Trying to create and restore snapshots on a system using older versions of GRUB will result in a non-bootable system.
  • EFI systems are fully supported. Ensure that the /boot/efi partition is mapped while restoring a snapshot. It will be mapped automatically if detected.
  • If you are restoring from Live CD/USB, and your installed system uses EFI mode, then you must boot from Live CD/USB in EFI mode.
