If you are a high-end software developer, system admin, or content creator who changed their Alien ID to the Linux world, then this article piece is for you. There is no worse enemy to a committed Linux enthusiast than data loss. To deal with data loss, you must understand the essential services of backup tools software.
You might be thinking, well, my machine system has several partitions. One has my Linux operating system installed, and the remaining ones I use to back up the data that I continuously use and develop. Moreover, you might be considerate enough to acquire an external hard disk drive to store your important files. However, the game of data loss is like playing chess against a supercomputer. The odds are never in our favor. It is usually when everything is going smoothly that an unfortunate event tends to introduce itself.
An unstable surge could occur and put your entire machine system in an ICU state. Such circumstances tend to corrupt or put your important data in an irretrievable state. Furthermore, a filled coffee mug that puts your ingenious mind in an active and productive state could accidentally spill on your machine or external HDD and commit the highest level of treason. This coffee that keeps our minds awake could have the opposite effect on our machines and any other external storage devices. Worse still, you will be forced to stay awake the whole night to mourn your data loss because the dark shades of coffee you took are still in your system.
Linux Backup Solutions
The union between our life and the Linux world is perfect for individuals in sync with its flexibility and open-source nature. Since you can do almost anything under Linux, you would not want to lose almost everything because you do not have an effective backup plan.
The concept of data backup is straightforward. The same way you copy files to a different location on your machine is the same way data backup works. The only difference is that the file copies you backup go to a secure and high-performing external machine system. You do not have to worry about not seeing your files again. Therefore, when your coffee mug decides to go on a rogue mission and test your anger management threshold, you can smile back and say, “back off, I have a backup.”
Since the backup strategy we recommend is cloud-based, come rain or shine, you have the perfect data backup plan. We might have failed to mention other data loss agents in our lead paragraph, like malicious malware and users. Such malware might figure out a backdoor into your system and do some irreparable damage. The malicious users are what we sometimes call the black hat hackers. They comprise of advanced Linux users who use their Linux skills for evil.
On top of having an impenetrable security layer over your backed up data, the Linux backup tools remove one major drawback that affects all of us, backup scheduling. Most of the time, we are too excited and committed to working that we forget to backup our files. Most Linux backup tools have a functional feature that will achieve this objective for us, even in our sleep. Therefore, all you have to do is point out whether you need your file backups once or twice a day or even weekly.
Enough with the Linux backup tools fairy tale; let us review them one by one.
The Best Linux Backup Tools
Since this backup software is open-source, there is no need to worry about associating a price tag with your data’s worth.

If you have an unending love for the Linux terminal, then you will fall head over heels for Rsync. It is a Linux-based command-line backup tool. However, it does not just favor the advanced terminal-based users as it is also considered the other Linux enthusiasts. Its GUI version very much welcomes the other portion of Linux users. Moreover, a tool with such advanced functionalities would require a GUI to lessen the strain that might affect system administrators. However, as Rsync is for the CLI (command-line interface), Grsync is for the GUI. Therefore, as a system administrator grows in experience, they will transition from Grsync to Rsync comfortably.
- Memory friendly. It only needs minimal memory storage to execute its functionalities efficiently.
- It supports incremental backups, which implies adjusting to an increased backup schedule through this feature.
- Offers support for both remote and local backups
- Your already set file permissions and ownership remain preserved.
- After an operation that backs up new files on an already established backup directory structure, it will update both the file system and the directory tree.
You can learn more about Rsync and Grsync from their official site.
Another interesting Linux-based backup software is Time Vault. It is also an open-source backup tool. If you have interacted with an Apple machine, you might have come across Time Machine. It is also a backup tool and Time Vault is its Linux equivalent. It has a unique functional algorithm where the scheduled backup files are created in increments. Therefore, after collecting the needed backup files in segments, it restores and restructures these file segments into complete file systems. The file structure is then returned to its original state.
The naming convention of this backup tool also relates to how it operates. Since it uses snapshots, a backup directory can contain a snapshot of a particular point in time and detail the related backup data. However, even if the snapshots can account for data backup on a calendar period, their limited storage capacity makes it difficult to account for entire file structures. Furthermore, if the snapshots’ assigned storage can accommodate your backup files, then you can time travel with Time Vault and access a specific backup before its modification or update took place.
However, take the news with a pinch of salt as this wonderful app has not been updated since 2007. We included it to bring the project into the limelight so that interested developers can contribute and take over the app development.
- Supports an incremental backup functionality
- Its snapshot applicability can be of an entire backup data storage. You, therefore, have a calendar backup of every backup instance.
- The GUI of its front-end is structurally appealing to all users.
- Zero complexities involved in its installation process
- It versions all its backup, making it desirable for users to access earlier unmodified data.

Symantec Ghost Corporate Edition is responsible for the creation of this backup tool. Its functional basis is tied to DRBL (Diskless Remote Boot in Linux). Since DRBL is a server, the associated client machines benefit from the diskless or systemless environment. Its usefulness is effective when associated with Clonezilla to clone target machines to achieve efficient backups.
Therefore, Clonezilla’s main functional mechanism relates to partial cloning, image partitioning, udpcast, among others. We can also add recovery and bare metal backup udpcast to its functionality list. Clonezilla, moreover, exists in two functional versions. We have the Clonezilla SE and Clonezilla Live. The SE version is effective on a server machine, while the Live version is efficient enough for a single machine with simple directory structures.
- Offers an ‘Unattended Mode’ functionality
- Come with multi-file system support
- Its imaging and cloning features are customizable

This tool also has a unique functional approach. Its steps of achieving successful data backup entail an initial production of encrypted volumes. These encryption adhere to a tar-format. If successful, Duplicity then uploads the encrypted backup-ready directories to a specified local or remote file server. This backup tool also makes use of the librsync library. The library primarily facilitates delta-compression of associated network streams and files. Therefore, duplicity additionally promotes incremental archiving. It mainly works with the entered system logs of the recently backed up files and directories. Finally, Duplicity will also borrow the encrypting functionality of GnuPG to secure or sign the newly uploaded file or directory archive.
- Very easy to use and does not require a user with an advanced skillset to make sense of it.
- Offers efficient storage and bandwidth
- Archives can be signed and encrypted
- Offers an optional remote protocol functionality
- Supports standard file formats
You can access Duplicity from its official site.
Its creation drew inspiration from the Rsync data backup tool that we already discussed. Therefore it mirrors Rsync’s functionalities like the incremental creation of files’ backups. Similarly, these file segments then get later restored to a file structure that is a duplicate of the original directory before the backup process started. The endgame of this approach is to create a chronological view of a backed-up file system. Therefore, users can preview or retrieve specific files or directories based on their backups’ system time logs. This additional control also makes it an efficient file manager as a user can navigate to a previous time log and access the associated files and directories.
- Caters for the automation of selective backups
- Flexible backs-up of user-specified directories to both remote and external destinations like an external HDD.
- Specific backup deletions by selection
- The backup process entails scanning entire directory structures for file changes.
- The system user manages the inclusion and exclusion backup list and also the backup location.
- You can schedule and initiate multiple backup tasks.
- The GUI is structurally friendly to all users
