5 Open Source Backup Software For Linux




good backup plan is essential in order to have the ability to recover from

  • Human errors
  • RAID or disk failure
  • File system corruption
  • Data center destruction and more.

Here you have some suggestions:

Important features the backup software should have:

  1. Open source software – You must use software for which the original source code is made freely available. 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.

AMANDA is an acronym for Advanced Maryland Automatic Network Disk Archiver. It allows the sysadmin to set up a single backup server to back up other hosts over network to tape drives or disk or autochangers.

Amanda: Open Source Backup

Amanda is the most popular open source backup and recovery software in the world

UrBackup – Easy to setup client/server system

It is an easy to setup open source client/server backup system, that through a combination of image and file backups accomplishes both data safety and a fast restoration time.

UrBackup also continuously watches folders you want backed up in order to quickly find differences to previous backups. Because of that, incremental file backups are really fast.

Your files can be restored through the web interface, via the client or the Windows Explorer while the backups of drive volumes can be restored with a bootable CD or USB-Stick (bare metal restore). A web interface makes setting up your own backup server really easy.

Currently there are over 10,000 running UrBackup server instances (with auto-update enabled) with some instances having hundreds of active clients.

  • Operating system : Linux/FreeBSD/Unix/Windows/several Linux based NAS operating systems. Client only runs on Linux and Windows.
  • Backup Levels : Full and incremental
  • Data format: Open
  • Autochangers: N/A
  • Backup media: Disk/Raid storage/DVD
  • Encryption datastream: Yes
  • License : GPL v3+
  • Download url : urbackup.org

Other open source backup software for your consideration

The Amanda, Bacula and above-mentioned software are feature rich but can be complicated to set for small network or a single server. I recommend that you study and use the following backup software:

  1. Rsnapshot – I recommend this tool for local and remote filesystem snapshot utility. See how to set and use this tool on Debian/Ubuntu Linux and CentOS/RHEL based systems.
  2. rdiff-backup – Another great remote incremental backup tool for Unix-like systems.
  3. Burp – Burp is a network backup and restore program. It uses librsync in order to save network traffic and to save on the amount of space that is used by each backup. It also uses VSS (Volume Shadow Copy Service) to make snapshots when backing up Windows computers.
  4. Duplicity – Great encrypted bandwidth-efficient backup for Unix-like system. See how to Install Duplicity for encrypted backup in cloud for more infomation.
  5. SafeKeep – SafeKeep is a centralized and easy to use backup application that combines the best features of a mirror and an incremental backup.
  6. DREBS – DREBS is a tool for taking periodic snapshots of EBS volumes. It is designed to be run on the EC2 host which the EBS volumes to be snapshoted are attached.
  7. Old good unix programs like rsync, tar, cpio, mt and dump.

Conclusion

I hope you will find this post useful to backup your important data. Do not forgot to verify your backups and make multiple backup copies of your data. Also, RAID is not a backup solution. Use any one of the above-mentioned programs to backup your servers, desktop/laptop and personal mobile devices.
