How to use Timeshift to backup and restore a Linux system

As a highly customizable operating system and heavily dependent on CLI interactions, Linux is prone to system failures due to incorrect system commands or operations. So if you use Linux on your main computer, you might run into problems often.

Luckily, there are system restore tools that take snapshots of your files and settings, which you can restore on your system to bring it back to a previous operating point in the event of any manipulations. Your actions render the system unusable.

Timeshift is one such tool for Linux. And in this tutorial, Tipsmake will guide you through using Timeshift on a Linux computer.

How to Install Timeshift on Linux

Timeshift comes pre-installed on some Linux distributions. With other distributions, you need to install them manually.

1. On Ubuntu and its derivatives

If you are using Ubuntu and its derivatives like Linux Mint, elementary OS, etc…, you most likely have Timeshift pre-installed on it. And so you can start using it right away.

However, in case it's not there, you can install Timeshift on Ubuntu by running the following commands in the terminal:

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

Alternatively, you can go to the Software Manager on your distro and install Timeshift from there.

2. On Fedora, CentOS and RHEL

Timeshift only supports BTRFS snapshots in Fedora. To get it use:

sudo dnf install timeshift

3. On Arch Linux and Manjaro

Finally, on Arch Linux, Manjaro and similar distros, you can install Timeshift with:

yay -S timeshift

Run and Initialize Timeshift

After you have installed Timeshift, open the Applications menu, search for Timeshift and launch it. It will ask you to enter the user password for authentication. Enter the password and tap Authenticate.

The Rsync option creates snapshots using rsync and hard links. Essentially, an Rsync snapshot contains only files and directories that have been changed or modified - the rest of the files (which are unchanged) are not backed up in the snapshot. Therefore, it takes up less disk space. On the other hand, Btrfs mode is ideal for users using one of the Linux distributions that use the btrfs file system.

After selecting a suitable snapshot type, click Next.
