Open source networking vendor automates backup
Vyatta has changed the networking world by developing the first commercially supported, open source router and firewall solution. These solutions include appliances that are pre-integrated with Linux-based router, firewall and VPN software. Founded in 2005 and headquartered in Belmont, CA, Vyatta’s customers include: municipalities, telecoms, colocations, and universities. Vyatta clients are thought leaders who recognize the benefits of flexible deployment options such as: x86 hardware, blade servers, and virtualization. The company’s customers like the freedom of integrating applications of choice with the economic and performance advantages of commodity hardware and components.
Vyatta uses open source technology in-house in addition to selling open source networking appliances, and Vyatta’s IT administrators at one time wrote custom scripts based on Linux dump. Whenever they added a server to the environment new scripts had to be created.
“The custom scripts were not able to scale and they lacked reliability,” says Ray Zhu, senior IT manager, Vyatta. “We spent a lot of resources maintaining the scripts.”
Vyatta backs up its Web sites, e-mail server, source-code repository, databases, and user files (approximately 2TB); and the amount of company data doubles each year. To stave off the need hardware purchases, Vyatta uses standard compression in its backups.
Open source backup fits Linux
Zhu researched backup-and-recovery solutions from Acronis, Bacula, EMC, and Symantec before choosing Zmanda. Zhu said that most big-name software solutions did not provide for the various flavors of Linux that Vyatta uses for its servers. Zhu added that Linux-compatible solutions do not offer a graphical user interface, but Zmanda’s Amanda Enterprise Edition has an attractive GUI and it works well with Linux.
Using two backup servers and ten clients, Vyatta’s servers run Red Hat Enterprise 5 on Dell PowerEdge hardware and others. Clients include Fedora, Debian, RedHat, and Ubuntu.
Zhu installed Amanda Enterprise by himself and he only had a few easy-to-solve support questions for Zmanda’s tech support staff during the installation process. Overall, the interaction with Zmanda proved to be effective and swift.
“Zmanda’s customer support is first rate,” said Zhu. “Their staff has the best expertise, and I always get prompt and to-the-point answers.”
Since installing Amanda Enterprise new servers have been added easily, and the Web-based GUI has made it simple for Zhu to create backups, view schedules, and generate reports.
Using Amanda Enterprise backup-scheduling function, full backups are followed by incrementals during the week. Every system is backed up at least once per week, and recovery is painless.
“I’m able to recover the system using basic Linux tar and gzip commands without Zmanda or Amanda. When it comes to recovering data, you don’t want a lot of dependencies,” said Zhu.
With the combination of Amanda Enterprise Edition and Zmanda Recovery Manager for MySQL, Zhu concluded, “Every morning, I have peace of mind after looking at the Zmanda backup logs.”
