Open Source Storage: 54 Tools for Backup and Recovery

Between cloud backup services, dedicated appliances and archiving software, backup and recovery is a huge business. And many organizations are governed by regulations that mandate backup procedures, which is only driving up demand.

According to one estimate, backup and recovery software sales are worth $4.7 billion dollars per year, and that's just for enterprise users. As data volumes continue to grow by 40 percent per year, both businesses and individuals are looking for ways to safeguard ever-increasing stores of information.

The open source community offers a variety of tools that can minimize the costs associated with backup and recovery. We've updated our list of open source backup tools for 2015, and this year's list has quite a few new entries that weren't featured last year. In addition, we've dropped off several projects that are no longer actively maintained.

If you know of additional open source projects that you think should be on the list for the next time we update it, please feel free to note them in the comments section below.
