How to Back Up Your Linux Install Using Timeshift on Debian and Arch-Based Distros

by

Backing up your system is an essential part of maintaining your Linux install because it protects your data from hardware failure, accidental deletions, or corruption. One of the best tools for this job is Timeshift, a utility that provides functionality somewhat analogous to the System Restore feature in Windows or Time Machine in macOS. Timeshift allows you to take incremental snapshots of your file system at different points in time. You can then use these snapshots to restore your system to a previous state. Here we will guide you through the process of setting up and using Timeshift on both Debian and Arch-based distributions.

Installing Timeshift

Debian-Based Distributions

On Debian-based systems like Ubuntu, installation is straightforward:

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

Arch-Based Distributions

For Arch Linux and derivatives, Timeshift can be found in the AUR (Arch User Repository):

  • If you’re using yay as your AUR helper:
yay -S timeshift
  • If you’re using paru as your AUR helper:
paru -S timeshift

Or, if you’re using another AUR helper or prefer manual installation, you can follow that specific process.

Configuring Timeshift

First Run

Upon opening Timeshift for the first time, you’ll be greeted with a setup wizard. The wizard will take you through selecting a snapshot type. For most users, “RSYNC” is recommended. However, if you are using a BTRFS file system, you may choose to take advantage of BTRFS snapshots, which are faster and consume less space.

Snapshot Levels

You can also set the frequency and levels of snapshots. A good starting point is to keep daily snapshots for the past seven days, weekly snapshots for the month, and monthly snapshots for the year. This can be adjusted according to your needs and available disk space.

Location

You will need to choose a location to store your snapshots. It’s often wise to save them to an external or secondary drive in case your primary drive fails.

Creating Snapshots

With Timeshift configured, you can take snapshots manually or let the scheduler handle them automatically. To create a snapshot manually, follow these steps:

  1. Open Timeshift.
  2. Click on the “Create” button.
  3. After the snapshot is created, it will appear on the main screen along with any others you have made.

Restoring from Snapshots

Should you need to restore your system, Timeshift makes it simple:

  1. Launch Timeshift and select the “Restore” button.
  2. Choose the snapshot you want to roll back to.
  3. Follow the on-screen instructions to complete the restoration process.

Timeshift on Different Distributions

While this guide covers Debian and Arch-based distributions, Timeshift is versatile and can be used in a similar fashion across various Linux distributions. Always ensure you have adequate space for backups and store them on a reliable medium.

Conclusion

Timeshift is a powerful and user-friendly backup solution for Linux that ensures your system and data stay secure. Whether you’re using a Debian-based or Arch-based distro, setting up Timeshift could not be simpler, and the peace of mind it brings is invaluable. Regular backups are a crucial part of any data management strategy, and with Timeshift, you can easily implement a robust system to protect against data loss.

Make it a habit to check on your backups periodically to ensure they’re up to date and consider testing a restore process to become familiar with it before you actually need to rely on it in an emergency situation. Enjoy your safer, snapshot-backed Linux experience!\
