To overcome these issue, there are a lot of open source backup software tools that are available that can help protect your data. And nowadays, computer desktops come with huge storage capacity and in turn it means lots of data being stored. This also leads to a huge risk of losing all the data if the system gets crashed and it may take several days and weeks to recover and repair the damage cause. Hence it is increasingly important to have a proper recovery solution with you all the time.
In this article we are going to review some of the top 12 open source back up tools for Linux systems:
When it comes to open sources backup tools for linux systems, Bacula is one of the most widely used and popular backup and recovery solution for linux system. It also helps in verifying the data across different computer networked systems effectively. Bacula comes with an effective and advanced storage management solution that helps you to recover all lost and damaged files pretty much quickly when compared to other backup and recovery solutions. It is the complete backup solution that is needed for a small or even a large enterprise to maintain and secure their data. Bacula comes with two versions, the Basic and Enterprise version.

Duplicati also conducts regular checks on the backups to detect for any broken/corrupt backup. All backups are provided with an AES-256 encryption and all backups are compressed and stored on the servers.
rsnapshot is a great filesystem snapshot tool that is capable of taking incremental backups in both local and remote filesystems. It is an rsync based backup system that can be used to take backup for any number of machines in the network. Since rsync is cleverly designed to use hard links, the disk space in your system is effectively used. By hardinks, it means even though it looks like taking a complete backup everytime, it only takes a full backup and then only the differences are backed up to save more space. With ssh, rsync can be used to take snapshots of remote systems as well.
Advanced Maryland Automatic Network Disk Archiver also called as Amanda is another great open source backup and recovery software for linux systems. It is basically an enterprise grade backup solution and according to the company, Amanda is running on around a million servers and desktops worldwide across various operating systems including Linux, Windows, UNIX, MacOS, BSD etc., Amanda comes in three different editions including Community edition, Enterprise edition and Zmanda Backup appliance. The community edition is freely available for download whereas the enterprise edition supports live application backups and databases. The Zmanda backup appliance is a virtual machine that is capable of backing up an entire network easily.
5) rsync (Command line tool)
Rsync is another popular linux open source tool that helps in quick incremental file transfers. Rsync can help you to transfer files to local host to remote host and vice-versa. The remote-update protocol enables the speedier file transfers as it checks if the destination file already exists and stops copying the file again. The delta-transfer algorithm also enables it to sync remote files easily and quickly as it doesn’t send the overall file, but only the differences are only sent and hence the sync is pretty much quick.
BackupPC is another enterprise range open source backup tool that supports all major operating systems including Windows, Linux and Mac. It is also a high performance backup system that utilizes compression and pooling setup that greatly reduces the disk storage along with disk I/O.
7) Rear (Relax & Recover)

It is available in two versions including the Clonezilla Live edition and Clonezilla SE edition. It is a complete free and open source backup utility and the Live edition is ideal for taking backup and restoring of single systems whereas the SE or the server edition is perfect to take huge server backups. One of the important features of this cloning utility is that it only used blocks and restored in the hard disk and thus enhancing the cloning efficiency.
9) Back in Time
Back in Time is an rsync based backup utility that comes with an interesting feature of using hard links during the backup process. Since hard links are used in this backup utility, it is easy to remove old snapshots by looking at the snapshots at regular intervals. Back in Time also doesn’t allow compression.
