10 Easy Ways to Restore Your Linux System linux system restore undo e1458244040149

Reverting your operating system to a previous state without consequences sounds almost like magic. You can quickly return to your work as if nothing happened, even when you don’t know what caused the problem. That’s why the System Restore feature is among the top things ex-Windows users want from Linux. Some go as far as proclaiming that Linux will never be as good as Windows 5 Lies Linux-Haters Like To Tell Linux may have been a scary operating system before, but all of that has changed in recent years. These myths, which are more accurately called lies, are now dead. Read More because it lacks System Restore.

Those users should read the manual, or even better, this article, because today we’ll present the tools that bring System Restore functionality to Linux. True, they’re not always available by default, but neither is System Restore in Windows 10 How to Factory Reset Windows 10 or Use System Restore Learn how System Restore and Factory Reset can help you survive any Windows 10 disasters and recover your system. Read More . You could also argue that they don’t behave exactly the same as their Windows counterpart, but then again, the way System Restore works What You Need To Know About Windows System Restore Imagine the trouble you could find yourself in, if your system failed! The Windows System Restore feature could save your butt. This article explains how to create and use Windows restore points. Read More changed between Windows versions.

How Does System Restore Work in Windows?

The original System Restore feature dates back to 2000 and Windows ME (Millennium Edition). It could only restore system files and the registry, and it wasn’t particularly reliable System Restore Not Working? 5 Fixes for Windows 7 and 10 System Restore saves your PC from disaster. But what if it System Restored failed you? We've got the fix. Read More . Improvements arrived later, in Windows XP and Vista. Since then, System Restore relies on a system service called Volume Snapshot Service that can automatically create snapshots (“shadow copies”) of the system — including files that are currently in use — and turn them into recoverable “restore points”.


While this new approach offered more customization (users could allocate disk space for snapshots, and choose which directories should be monitored), it also brought limitations. System Restore snapshots work only with NTFS partitions, and in versions prior to Windows 8, they can’t be permanent.

Each new Windows version introduced further confusion, because “Home” editions of Vista lacked the interface for restoring previous snapshots, and Windows 8 made it impossible to recover previous versions of a file from Explorer’s Properties dialog. Finally, Windows 10 disabled System Restore altogether, leaving it to users to enable it manually. Most likely, this decision was intended to direct them towards Refresh and Restore Should You Refresh, Reset, Restore, or Reinstall Windows? Ever wanted to reset Windows 7 without losing personal data? Between a factory reset and a reinstall, it was tough. Since Windows 8, we have two new options: Refresh and Reset. Which one is right... Read More .

But enough about Windows. Let’s see how we can make this work on Linux.

How Does System Restore Work on Linux?

It doesn’t — at least not under that name. You won’t find the feature called “System Restore” in your distro’s menus. You’ll have to find an approach that suits you and install the necessary applications. Most of them are based on the same principle as System Restore on Windows. They create snapshots of your system at specified intervals and let you roll back to a selected point in time.


Before diving into the apps, let’s briefly explain what system snapshots are.

What’s the Difference Between System Snapshots and Backups?

Semantics may vary, but generally speaking, backups are copies of files Things You Should Know About Redundancy and Backups Redundancy is frequently confused with backups. Indeed, the concepts are relatively similar, albeit with some important differences. Read More kept in a location separate from the files themselves. Backups rarely include everything on a disk; when they do, they’re called disk images or disk clones How to Clone Your Linux Hard Drive: 4 Methods Need to clone your Linux hard disk drive or partition? Use one of these drive cloning tools to clone your Linux disk. Read More . This type of backup “mirrors” the entire disk, including user data, the operating system, boot sectors, and more. Disk images can be used in the bare metal restore process, where you copy the contents of a hard disk onto a computer without an OS.

Snapshots, on the other hand, are saved states of a filesystem created at specific points in time and kept on the same storage device as the filesystem. They usually include all directories and files of a filesystem, or at the very least, the files required by the OS.

Keeping the snapshot in the same place as the filesystem makes it possible to perform a rollback, but it also saves disk space. In this setup, each new snapshot doesn’t have to save the entire filesystem state. Instead, snapshots act like incremental backups and save only changes that were made since the last snapshot. This means that every snapshot depends on the previous one to fully restore the system. Conversely, a full backup or a disk image is independent of other backups, and can restore the system on its own.



The problem with snapshots is they’re vulnerable to disk failures — if your disk suffers severe mechanical damage, you’ll likely lose the snapshots along with the entire filesystem. To prevent this, it’s recommended to make a snapshot right after you install and set up your Linux distribution, and copy it to a separate storage device.

There are quite a few apps for Linux that can help you maintain system snapshots. Most of them are beginner-friendly and don’t require advanced Linux skills. Take a look at our selection and pick the app that’s best for your workflow.


TimeShift has a simple graphical interface, and you can also use it from the terminal. By default, it doesn’t include a  user’s personal files, but you can add custom directories to your snapshots. On Ubuntu and derivatives you can get TimeShift from the developer’s PPA:


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

while users of other distros can download the installer file and run it in the terminal:


There’s also a version for BTRFS filesystems From FAT To NTFS To ZFS: File Systems Demystified Different hard drives and operating systems may use different file systems. Here's what that means and what you need to know. Read More that supports the native BTRFS snapshots feature.

How it Works

TimeShift lets you take snapshots whenever you want, or you can set it up to create them automatically. You can schedule hourly, daily, weekly, and monthly snapshots, and configure how often TimeShift should remove them. There is a special option called Boot Snapshots that creates one new snapshot after every reboot.


Restoring a snapshot with TimeShift is a straightforward process: you select a snapshot and choose the location to which it should be restored. TimeShift offers the option to restore snapshots to external devices, and the Clone feature can directly copy the current system state to another device. This is helpful for migrating your OS to a new computer without having to set up everything from scratch.


Before restoring a snapshot, TimeShift will ask if you want to preserve application settings, and let you choose which ones to keep. Remember that TimeShift requires GRUB 2 to boot into a restored snapshot.


If TimeShift is simple, Cronopete is even simpler, at least in terms of appearance. It calls itself a clone of Time Machine for OS X 3 Ways to Restore Data From Time Machine Backups Here are several methods for how to restore your Mac using Time Machine, including what to do about "searching for time machine backups." Read More , and works a bit differently than TimeShift. Cronopete offers packages for Ubuntu, Debian, and Fedora, while Arch Linux users can find it in the AUR.


How it Works

Unlike other apps on this list, Cronopete combines the backup and snapshot paradigms and forces you to keep snapshots on an external device. By default, it checks your files for changes every hour, but you can change the interval in the configuration dialog. If a file has not changed, Cronopete will only hard-link to it instead of copying the file, which helps save disk space.


Restoring files is probably the coolest thing about Cronopete. It lets you “scroll through time”; that is, visually browse all saved versions of your files and folders. To restore files, simply select them and click Restore. They will be copied from the external disk onto your current system. As you can probably deduce, Cronopete is not very practical for a full system restore, but it’s a great choice if you want to keep multiple versions of individual files.

Back In Time

Back In Time Backup & Restore Data And Files Easily With Back In Time [Linux] Read More looks user-friendly enough to attract Linux beginners, while its Settings dialog offers fine-grained control. The interface acts like a regular file manager, and you can preview all your snapshots, browse files in each of them, and restore selected files and folders.


Back In Time can be installed from a PPA if you’re on Ubuntu:

sudo add-apt-repository ppa:bit-team/stable
sudo apt-get update
sudo apt-get install backintime-qt4

Several distributions offer it in their repositories, and if yours doesn’t have it, you can always download the source.

How it Works

Back In Time creates snapshots that include folders of your choice, but it can only restore those to which you have write access. Your snapshots can be encrypted and stored on a network device, an external disk, or your local filesystem. Back In Time updates only the files that have changed, and the Settings > Options tab lets you disable snapshots when no changes are required.

Snapshots can be scheduled (daily, weekly, monthly, several times per day, or only upon reboot) or you can create them manually by clicking the button in the main toolbar. The Settings > Auto-remove tab lets you define when Back In Time should remove old snapshots, and you can protect snapshots from deletion by giving them a name and selecting “Don’t remove named snapshots”.


Similar to Cronopete, Back In Time is more suitable for folder- or file-based rollbacks, but if you want to revert the entire filesystem, that’s also possible. Restoring a snapshot is as easy as selecting it and deciding whether you want to restore just a few folders or the whole shebang.


Systemback packs an impressive amount of features in a tiny interface. Unfortunately, only users of Debian, Ubuntu, and its derivatives can play with Systemback for now, because there are no installation files for other distributions. The developer provides a PPA:

sudo add-apt-repository ppa:nemh/systemback
sudo apt-get update
sudo apt-get install systemback

How it Works

Systemback isn’t just another snapshot tool. It can turn your current system into a live CD or DVD that you can boot on another computer. It can fix or reinstall the GRUB 2 bootloader, and repair the fstab file. Still, you’ll probably use it primarily for system snapshots.


Systemback limits the total amount of snapshots to ten, trusting you with the task of removing them. Snapshots can be incremental (only changed files are copied; the rest are represented by hard links), but you can disable this in the Settings dialog. When restoring files, you can perform a full restore or just copy the essential system files. Your personal data, such as pictures and documents, won’t be included in the snapshots, but you can transfer them to a live CD with the Live system create > Include user data option.


Systemback lets you customize the snapshot schedule, but you’re free to turn this off and create restore points manually. It’s important to remember that Systemback doesn’t support the NTFS filesystem, so you won’t be able to restore a snapshot to or from a partition formatted as NTFS.


Snapper is closely tied to openSUSE, where it was introduced in version 12.1. It’s possible to install it on other distributions, but it’s not guaranteed to work. The easiest way to set up Snapper is to install openSUSE on a BTRFS partition; in that case, Snapper gets automatically installed and configured. You can use Snapper as a command-line tool or through YaST, and there’s an alternative called snapper-GUI.

How it Works

Snapper makes several different types of snapshots. Pre and post snapshots are made before and after installing new packages with zypper or YaST, and when you modify the system through YaST modules. That way you can compare snapshots and revert to the old state if the changes cause trouble. Timeline snapshots are created automatically every hour, unless you disable them. All other snapshots are called single, including those you create manually. Snapshots reside on the same partition for which they are created, and they grow in size, so keep that in mind when organizing your disk space.

By default, Snapper creates snapshots only for the root partition. To include other partitions and BTRFS subvolumes, you have to create a configuration file for each of them. This has to be done from the terminal. Make sure to run the command as root:

snapper -c CONFIGNAME create-config /PATH

Here -c stands for “configure”, CONFIGNAME is the name you choose for the configuration, and /PATH is the location of the partition or subvolume. For example:

snapper -c home create-config /home

You can check currently active configurations with:

snapper list-configs

All configuration files are saved in /etc/snapper/configs, and you can modify them in a regular text editor. For example, you can disable hourly snapshots, toggle automatic snapshot removal, and tell Snapper how many old snapshots to keep.

The YaST Snapper module lets you create and compare snapshots. You can also roll back to a previous snapshot, as well as restore a previous version of a single file or a number of selected files.


An additional rollback method is provided by the package grub2-snapper-plugin for openSUSE. This lets Snapper boot into a snapshot and restore the system directly from the bootloader menu. If it’s configured properly, there should be an option in GRUB 2 called “Start bootloader from a read-only snapshot”. On other distributions you can try grub-btrfs to get similar results. Note that you can only boot snapshots created for the root partition.

How to Backup and Restore Installed Applications

Instead of reverting the entire OS, sometimes you’ll just want to restore the software you installed. This is often the case with distro-hopping, reinstalling your current distribution, or upgrading it. Luckily, we can rely on these handy tools that simplify the app migration process.

The first mention goes to Aptik, an application backup utility created by the developer of TimeShift.


It’s only for Ubuntu-based distributions, and you can install it from the developer’s PPA:

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

Aptik can export the list of currently installed packages along with the list of repositories you use and the downloaded packages themselves. There are also options for exporting application settings, desktop themes, and icon sets. Aptik categorizes the packages by installation type (preinstalled with the OS, installed by the user, installed automatically as dependencies, and installed from .deb files). It lets you drag-and-drop downloaded .deb files into the list to include them in the backup. You can keep the backup anywhere you want, and extract it to a freshly installed distribution by installing Aptik first and selecting Restore in the main application window.


Linux Mint users can try Mint Backup Tool, which functions almost exactly the same as Aptik. Apart from restoring installed applications, this tool can perform a quick backup of a selected folder and its permissions.


Those who run Arch Linux can turn to Backpac. It creates lists of manually installed packages (both from the official repositories and the AUR) and can backup individual files of your choice. Restoring the system state with Backpac boils down to installing the exported packages, removing the ones that were not included in the snapshot, and overwriting the system files with their previously exported version.

Of course, there’s a way to do all this without a third-party app, using only the tools provided by your package management system. On dpkg-based systems, you can export a list of installed apps with:

dpkg --get-selections > /home/yourusername/apps.txt

then copy that file along with repository information from /etc/apt/sources.d/ and /etc/apt/sources.list to the new system. Provide the correct path to the apps.txt file, and migrate the apps to the new system with:

dpkg --set-selections < /path/to/apps.txt
sudo apt-get update
sudo apt-get dselect-upgrade

Some graphical package managers (Synaptic, for instance) can export and import lists of installed applications, so you don’t have to do that from the terminal.


Advanced System Rollback Solutions

Perhaps the applications we’ve suggested so far simply don’t cut it for you. The good news is that other solutions are available. Calling them “advanced” doesn’t mean they’re overly complicated; just that they might not be suitable for a beginner’s first choice.

Rsnapshot [No Longer Available]

If you’re looking for a quick way to take snapshots from the terminal, give rsnapshot a try. You can find it in the repositories of most Linux distributions. Rsnapshot keeps all its settings in /etc/rsnapshot.conf, and it’s here you’ll define the snapshot schedule, when to remove old snapshots, as well as which files and folders to actually include. Once you’re happy with the configuration, test rsnapshot with:

rsnapshot configtest
rsnapshot -t hourly

to ensure everything runs smoothly. Remember that rsnapshot’s configuration file requires tabs between options, not spaces, so don’t move the parameters around by pressing the spacebar. There is no automatic restore feature, though, so you will just have to copy the files manually from a selected snapshot.


Obnam is similar to rsnapshot, with some additional interesting features. First it creates a full backup of your system, then builds incremental snapshots containing only new and/or changed files. Your snapshots can be encrypted, and Obnam handles decryption automatically. The same applies to restoring your snapshots: there’s a command for that, and Obnam lets you choose where to restore them.


You can include and exclude custom paths, and store your snapshots on a server or other remote location. Naturally, there’s a way to remove aged snapshots, and the official user manual is a great piece of documentation that explains everything.

LVM Snapshots

When it comes to preserving precious data, it’s always a good idea to think about it in advance. If you’re just setting up your Linux system, it’s worth considering LVM (Logical Volume Manager) Combine All Your Hard Drives Into One Seamless Storage Container With LVM [Linux] If you tend to use up a lot of storage, you'll probably have had some storage problems. You might still have a lot of empty hard drives lying around, but splitting up all your data... Read More as a way to organize your hard disks.


Why? Although it’s not exactly an app, the LVM implementation in the Linux kernel comes with an in-built snapshot feature. You can mount the snapshots and browse them as any other disk or partition, merge several snapshots, and restore them to resolve system problems. Alternatively, you can use dattobd, a Linux kernel module that supports incremental snapshots of a live, running system without having to unmount partitions or reboot the computer.

As you have seen, you have many options to get the System Restore functionality on Linux, yet they’re all technically very similar. Is there a better way to replace System Restore on Linux? Maybe it will be revealed in the future as these apps continue to develop, or maybe it hides in a combination of already existing tools.

What do you think? Have you used any of these apps? Would you agree that Linux needs something like System Restore? Join the discussion and share your advice in the comments.

    Hi, my name is Alfredo, I have a little problem with my son's computer, in 2103 when he was in 6th grade, the Mexican government started a pilot program called Program MiCompuMX, which gave new computers to about 240,000 students, the program ran on 3 states and only on selected schools, my son's school was one of them. The laptops were:
    Screen Size: 10"
    Memory: 1.7gb
    Procesor: Intel Celeron(R) CPU 847 @ 1.10Ghz x 2
    Graphics: Intel Sandybridge Mobile
    Type of OS: Debian Wheezy 64bit Gnome 3.4.2
    HD: 288.5GB

    I tried to upgrade it to the most recent version, Debian Jessie, and it made a whole mess, I had to go back to the original version, Debian Wheezy, then I did a simple update and the same thing happened, now I can't log back in, even after using the Boot-Repair-Disc, my question is: Is there a way to use a Linux Live USB to backup software installed in the laptop using one of the tools mentioned on this post?
    That way I can install a fresh copy of the most recent version of Debian and then just restore the software.
    I'd really appreciate any advice, thanks!

    How do you restore your linux OS if you accidently uninstalled or deleted it

    It's when I see articles like this that I am SO glad I run 'Puppy' Linux. You back up your entire partition on a regular basis; takes maybe 10 minutes. This includes Puppy's 'save-file', which is a unique file, containing an entire Linux file-system, with all your system settings and configurations.

    Anything goes wrong, you wipe the partition, re-format with gParted, literally copy'n'paste the backup into the 'new' Puppy's boot-loader, Grub4DOS..... and within less than 30 mins it's as though it had never happened.

    Puppy is the ONLY Linux distro I know of that you can restore with a simple copy/paste operation..!

    An important point that should be made in comparing McSoftware OS to a linux distro such as Ubuntu when it comes to recovering from complete system failure is this:

    While it is possible to take a disk image backup of the entire operating system and contents in every case, the recovery time for critical applications is hampered by the amount of time it takes to return to a bootable state. If we're talking hardware failure, there is almost no chance that a McWindows (would you like fries with that) will recover gracefully through any kind of restore. There is so much "anti piracy" code built into the OS and applications that invariably the system administrator must go reaching for installation media to "repair" the installation of first the OS, and then each subsequent application that goes into nag mode.

    Linux on the other hand (I'm going to focus on Ubuntu specifically) will enable you to perform an installation of the OS and be operational (at a basic level) in approximately 15 minutes.
    Once you're back on the air, install your backup/recovery suite from the repository and begin restoring.. but if you're in a real hurry for particular applications and data to be available while other lesser priority content is brought back online, then there is nothing faster than rsync (assuming you really are coming back from the dead).

    You have control with rsync to restore the whole shooting match, or selectively restore content that matters: For example, I might want to restore the /Documents/. contents first, or the /.thunderbird/ structure as a priority. I can be back on the air while stuff like virtualbox VMs or the thumbnail cache used by shotwell, banshee, etc continues to restore in the background.

    I use a combination of the package sbackup (simple backup restore) which seems to work a lot more elegantly than Backup in time, or dejadup, etc and regular rsync of /home/.

    Both the sbackup and rsync functions should be executed as root. This is critical if you are planning on supporting multi-user environments, let alone restoring system configurations. It is worth noting that these two functions should be exporting to external disks (a NAS, removable storage, FTP, SFTP, ..)
    rsync as a cron task can be set to run at a frequency you're comfortable with. I run incremental rsync frequently, and once a month purge the rsync target and run a fresh full rsync (because, for those who are not familiar, rsync does not remove files from the target you chose to eliminate from the source, it just adds and increments changes).

    The sbackup tool runs frequent logarithimic scheduled backups and emails a report of the result (from all the computers I use it on). It is useful for those smaller "oops" moments.

    The rsync backup is a guarantee that all data exists (somewhere) for that complete system rebuild (not restore).

    This approach means that you're not restoring an OS to a deprecated state: You have the latest OS (assuming your distro is readily available from a mirror), and you are simply adding back the data and app configurations you need.

    My method does not cater for restoring "as they were" applications. The assumption is that the repo you use with your distro contains those applications, and that what you're interested in restoring is the data and configurations the applications use.

    This combination of rsync and sbackup is robust also when faced with an upgrade or new version of your distro. The same process applies: Make sure you have a recent rsync copy, and that your sbackups are current. Perform a clean install of the new release, and begin your "recovery" process. To a degree, a network admin can apply the same technique across multiple machines.

    The best part is that this process has been viable now without alteration since I first started really understanding my linux OS in the mid naughties.

    A final thought as far as target backup sources are concerned: In my experience it has mattered not whether the target backup disks are formatted as EXT4, EXT3, or NTFS.

    What is the use of snapshots when you must restore after a hard drive failure? You first must restore the last disk image, then restore all the snapshots between the last disk image and the point of failure. Seems like a drawn out, time consuming process.

    • Ivana Isadora Devcic
      March 30, 2016 at 5:38 am

      I suppose this depends on what kind of hard drive failure we're talking about. If it's a severe one, it might not be possible to restore anything. That's exactly why it's recommended to keep a separate backup of snapshots (or at least one full disk image). I agree that this complicates the matter.

      However, the process of restoring the snapshots isn't that time-consuming - it's just a few clicks in the app. You'd wait for it to complete just like you would wait for the installation of a new distro and new apps to complete after your disk has been wiped. I'd much rather have everything restored - provided that the snapshots were intact, of course - than have to install and set up everything all over again.

      But that's just me; maybe you know something I don't. :) Do you have any better ideas how to pull this off in a less time-consuming fashion?
