15 Open Source Cloud Storage Software for Linux in 2024

The term “cloud” suggests something immense, extending across a vast expanse. In the realm of technology, “the cloud” refers to a virtual entity that offers services to end-users, including data storage, application hosting, and the virtualization of physical resources.

In today’s landscape, cloud computing is harnessed by organizations of all sizes to store data and provide customers with the benefits outlined above.

Primarily, there are three types of cloud services:

  • SaaS (Software as a Service) – This service enables users to access publicly available clouds provided by large organizations for data storage, such as Gmail.
  • PaaS (Platform as a Service) – PaaS allows users to host applications or software on other public clouds. For example, Google App Engine hosts user applications.
  • IaaS (Infrastructure as a Service) – IaaS virtualizes physical machines, making them available to customers and providing an experience similar to using a real machine.

What is Cloud Storage?

Cloud Storage refers to the practice of storing data on remote servers rather than on users’ local systems. This concept dates back to 1983 when CompuServe initially provided its customers with 128k of disk space for file storage.

Since then, the field of cloud storage has undergone continuous development, and it will continue to evolve due to ever-present threats like data loss, information breaches, hacking, and other malicious attacks.

As a result, many organizations have stepped up to offer their own solutions in cloud storage and data privacy, contributing to the strengthening and stabilization of its future

In this article, we will showcase selected open-source cloud storage software for Linux that has gained widespread acceptance among both large organizations and the general public.

1. OwnCloud

As a Dropbox alternative for Linux users, ownCloud provides numerous functionalities similar to those of Dropbox. It operates as a self-hosted file sync and share server.

Its open-source functionality provides users with access to an unlimited amount of storage space. The project started in January 2010 with the aim to provide an open-source replacement for proprietary cloud storage service providers. It is written in PHP, JavaScript and is available for Windows, Linux, and OS X desktops, and even successfully provides mobile clients for Android and iOS.

OwnCloud employs a WebDav server for remote access and can integrate with a large number of databases including SQLite, MariaDB, MySQL, Oracle Database, and PostgreSQL.

Provides a large number of features countable which include: file storage and encryption, music streaming, content sharing across URLs, mozilla sync hosting and RSS/atom feed reader, one-click app installation, video, and pdf viewer, and many more.

The latest version of ownCloud i.e. 10 adds other new features including improved design, which allows the admin to notify users and set retention limits on files in the trash.

GlusterFS uses a client-server model with servers being deployed as storage bricks. A client can connect to a server with a custom protocol over TCP/IP, Infiniband, or SDP and store files to the GlusterFs server.

Various functionalities being employed by it over the files are file-based mirroring and replication, file-based stripping, load balancing, scheduling, and disk caching to name a few.

Another very useful feature of it is that it is flexible i.e. data here is stored on native file systems like xfs, ext4, etc.

9. Git-annex

Git-annex is another file synchronization service developed by Joey Hess, which also aims to solve file sharing and synchronization problems but is independent of any commercial service or central server. It is written in Haskell and is available for Linux, Android, OS X, and Windows.

Git-annex manages the git repository of the user without storing the session in git. But instead, it stores only the link to the file in the git repository and manages the files associated with the link in a separate place. It ensures the duplicate of a file that is needed in case the recovery of lost information is required.

Further, it ensures the availability of file data instantly as and when required which prevents files to present on each system. This reduces a lot of memory overhead. Notably, git-annex is available on various Linux distributions including Fedora, Ubuntu, Debian, etc.

  1. All these are great. However, they share one big problem. Your data is stored on somebody else’s server. As soon as you store your data on a third-party server, you give the server owner control over that data. You can be very easily blocked from accessing YOUR data. There is no Federal Deposit Insurance Corporation for when the server owner goes out of business.

  6. Hello, good article, but if you mentioned for each cloud storage how many GB are per free account, that would be great.

    • @Gheorghe,

      Thanks for finding this article useful, yes we do agree that we would’ve mentioned about storage per account, but their storage changes regularly, so its difficult for us to check every-time and update the article, you can get the details about storage on their official page..

      your point is noted, but they keep change their storage very ofenly, so
