Top 5 Data Backup Software for Linux

This article covers Data Backup Software for Linux. Data Backup and Protection are key concerns of many users, companies, and organizations. For this purpose, many data backup and data protection systems have been introduced and still many are being developed every day, deciding to choose and select the best and most suitable platform meeting needs and requirements. Each tool offers enhanced and state-of-the-art capabilities to provide the utmost data protection and data backup. 

All the listed and discussed backup software, i.e., Acronis, Nakivo, IDrive, MSP360, and Backblaze assure utmost performance and are acclaimed by its users.

However, the task of selecting one tool among the top five best-listed backup software solely depends on user requirements and expectations from the backup tool along with the cost one is willing to spend on the backup software. 

Other than that, each tool listed provides commendable features and data protection services.


What to look for when choosing backup software for an enterprise?

Make sure the following features are supported backup software you deploy:

1. Open source software – You must use software for which the original source code is made freely available and may be and modified. This ensures that you can recover your data in case vendor/project stopped working on software or refused to provide patches.

2. Cross-platform support – Make sure backup software works well on the OS deployed on all desktop and server operating systems.

3. Data format – Open data format ensures that you can recover data in case vendor or project stopped working on software.

4. Autochangers – Autochangers are nothing but a variety of backup devices, including library, near-line storage, and autoloader. Autochangers allows you to automate the task of loading, mounting, and labeling backup media such as tape.

5. Backup media – Make sure you can backup data on tape, disk, DVD and in cloud storage such as AWS.

6. Encryption datastream – Make sure all client-to-server traffic will be encrypted to ensure transmission integrity over the LAN/WAN/Internet.

7. Database support – Make sure backup software can backup database server such as MySQL or Oracle.

8. Backup span multiple volumes – Backup software can split each backup (dumpfile) into a series of parts, allowing for different parts to existing on different volumes. This ensures that large backups (such as 100TB file) can be stored on larger than a single backup device such as disk or tape volume.

9. VSS (Volume Shadow Copy) – It is Microsoft's Volume Shadow Copy Service (VSS) and it is used to create snapshots of data that is to be backed up. Make sure backup software support VSS for MS-Windows client/server.

10. Deduplication – It is a data compression technique for eliminating duplicate copies of repeating data (for example, images).

11.  License and cost – Make sure you understand and use of open source license under which the original backup software is made available to you.

12. Commercial support – Open source software can provide community based (such as email list or fourm) or professional (such as subscriptions provided at additional cost) based support. You can use paid professional support for training and consulting purpose.

13. Reports and alerts – Finally, you must able to see backup reports, current job status, and get alert when something goes wrong while making backups.

Backup and Restore MySQL Databases on Red Hat Enterprise Linux 8 - Step by Step Process ?

This article covers how to take Backups and restore a MySQL database on Red Hat Enterprise Linux 8.


Advantage of logical backup:

The main advantage of logical backup over physical backup is portability and flexibility. 

The data can be restored on other hardware configurations, MariaDB versions or Database Management System (DBMS), which is not possible with physical backups.

Note that physical backup must be performed when the mariadb.service is not running or all tables in the database are locked to prevent changes during the backup.


The mysqldump client is a backup utility, which can can be used to dump a database or a collection of databases for the purpose of a backup or transfer to another database server. 

The output of mysqldump typically consists of SQL statements to re-create the server table structure, populate it with data, or both. 

Alternatively, mysqldump can also generate files in other formats, including CSV or other delimited text formats, and XML.


Advantages of Physical backup:

1. Output is more compact.

2. Backup is smaller in size.

3. Backup and restore are faster.

4. Backup includes log and configuration files.


You can use one of the following MariaDB backup approaches to back up data from a MariaDB database:

1. Logical backup with mysqldump

2. Physical online backup using the Mariabackup tool

3. File system backup

4. Replication as a backup solution


To Backing up an entire database with mysqldump:

Execute the command:

# mysqldump [options] db_name > backup-file.sql


Using mysqldump to back up a set of tables from one database:

To back up a subset of tables from one database, add a list of the chosen tables at the end of the mysqldump command:

# mysqldump [options] db_name [tbl_name …​]



To restore the data while keeping the original backup files, use the following procedure:

1. Run the mariabackup command with the --copy-back option:

$ mariabackup --copy-back --target-dir=/var/mariadb/backup/

2. Fix the file permissions.

When restoring a database, Mariabackup preserves the file and directory privileges of the backup. However, Mariabackup writes the files to disk as the user and group restoring the database. 

For example, to recursively change ownership of the files to the mysql user and group:

# chown -R mysql:mysql /var/lib/mysql/

3. Start the mariadb service:

# systemctl start mariadb.service
