The recovery of personal data or operating systems in the event of a disaster can be fraught with uncertainty and worry about whether the backup tool will not leave out any crucial files.
It can be a daunting task for Linux users to backup their data because there are so many different tools available, such as Debian Arch Red Hat and others. Suse.
The process of choosing between different backup and restore strategies is complicated, because it requires constant adaptation to find the best software solution. You may want to choose backup software that can upload your files to a cloud storage or external media. The type of backup strategy you choose is also important.
Linux is not a one-size-fits all solution. There are four options: full, incremental differential and mirror. Each has its own limitations.
It’s just as dangerous to use the wrong type backup system as it is to not have any. It takes two steps to backup your Linux OS as well the data created by your apps. You may not be able to restore your data when you need it if one or both parts fail.
I have used computers for many years and backups of systems and files, both personal and system-wide, have occasionally been unreliable. Sometimes the problem was caused by the software. It can also be the result of the encryption and transmission process.
Glitches happen, no matter what the cause. You can use a back-up solution that’s more foolproof than foolish.
Old School Data Backups
Data backup is a way to prepare for the unavoidable.
In the past, when I had a desktop computer at home and a portable laptop, I would schedule automatic backups twice daily to the hard drive. I would copy the backup files from both computers to an external drive at the end of each week. This gave me two copies: one outside the computer, and another waiting on my local computer.
This allowed me to restore the most recent versions of applications and system files in case (never if!) a computer crashed. Then, I had to install Microsoft Windows on two machines in case there was a problem with file compatibility.
I installed multiple Linux distributions, one after the other, over time. This created a dual-booting system. This created the possibility of boot failures, which usually occurred on the Linux partition. Boot repair software didn’t always fix corrupted or deleted boot files. I lost track of how often my backup files saved the day — or failed.
Backup storage is critical.
My standard procedure was to store my personal data files as well as work documents on thumbdrives. I used software to copy the data files that had been changed from their designated folders and onto my external storage drive. The batch file copied the files from the portable storage drive to the hard disk when I returned to my other computer.
This procedure ensured — usually, anyway — that I had up-to-date replacement data files for both computers. The same method was used as I replaced or added additional hardware to “sneak” network my backups.
Cloud storage services such as Google Drive, Dropbox and others have replaced my thumb drive collections. Cloud storage and hard drives were kept connected with synchronization software.
Linux backups are difficult for beginners because the various Linux distributions make it difficult to guarantee complete reliability. The wrong backup system can be as damaging as none at all.
It is possible to back up both your operating systems and data created by apps in two different ways. The system files are the first part. Second, you have your data files and documents.
The backup tool may not be able to find these files if you don’t confirm the location. Start by checking the Linux home directory.
Three-2-1 Backup Strategy
In all the years I’ve used computers, both types have been unreliable at times. This could be due to software bugs or errors in the encryption and transmission of backup files.
To improve the reliability of my restoration, I have added a new trick: The 3-2-1 backup rule. This is a standard approach for keeping data safe under almost any failure scenario.
How to do it: Make three copies and save them on two different backup storage media. This gives you your original files on the drive plus two copies saved somewhere else. Choose a third copy to be saved off-site.
Uploading personal and system backups to a secure, trusted cloud is a component that I adhere to. The majority of off-site locations offer their own software or applications to make this process relatively easy.
How to Choose the Right Linux Backup Method
Understanding the different types of backup software will improve your chances of restoring files. Choose the right backup software for your operating system, whether it is Linux or Windows.
A full backup is similar to aiming a gun at a target. Backups are complete when they save all data onto a device. The process tracks all digital content on the device and grabs it.
It’s like shooting a squirrel with a shotgun. A full backup is overkill. This can take a long time and require more bandwidth and storage space. This is wasteful, as unaltered files are copied each time you run a backup.
The incremental backups are only those backups that have changed since the previous backup. Previous: backup. The backup takes up the least amount of space and is completed in the shortest time. It uses less computer resources.
Backups that are different only copy the files that have been modified since the previous backup Full Article backup. The name is a reminder that only “different data” is copied.
Mirror backups are copies of the data in selected folders or files, at a certain time. The process stores only the latest versions of files at the destination. Mirror backups of data files are the most common method for backing up data.
A mirror backup of system files is not a personal data backup. The files created are specific to the computer which created the file. If you use the same system backups on other computers, it is possible that they will interact badly with hardware differences and cause errors.
Finding Effective Backup Tools on Linux
Linux distributions usually come with preinstalled tools for backup. Comparing its features to the backup strategies outlined above will help you determine if it is suitable for your needs. You can replace it or add to it by using another Linux backup program you find in the software manager app of your distro.
You can search for “backup” using the main menu. This is the default name for any preinstalled backup software. The generic name could be different depending upon the distro. But the app’s name is different.
The two images below, for example, show the generic app Backup tool on the left side and the app’s About page next to it.

Both apps offer basic backup functionality. They both have a few options for what files to copy, and where they should be saved. The main difference is in the backup scheduling.
Ubuntu’s backup tool makes use of a popular and well-known app called Deja Dup. I have been using this app for many years on numerous distros. Linux Mint’s backup tool is otherwise indistinct.
Concluding Advice on Linux Backup Tools
Find a list on the Internet of Linux backup software. You can read their descriptions and learn more about the types of backups that they perform, as well as what options are available to users.
The menus of most backup tools are very similar, and can be used with just a few mouse clicks. If you are not a Linux veteran, do not use backup tools which run in the terminal. You must manually input instructions to run and start features in command-line programs.
Grsync, a well-known terminal application with graphical user interfaces (GUIs), is another example of a popular terminal program. A terminal program that has a GUI version will give you more options to meet your needs.
