Vyatta: From Homegrown Backup Scripts to Amanda Enterprise

Monday, September 29th, 2008

VyattaVyatta has rocked the networking world by developing the first commercially supported, open source router and firewall solution. Ambitions of changing the rules of the game of a huge industry, come with very critical data – which doubles in size every year! They also come with a very heterogeneous environment: Fedora, Debian, Red Hat, and Ubuntu – well, as long as it is a Linux distro 🙂

Vyatta recognized the need for a formal backup solution to replace the homegrown backup scripts, and chose Amanda Enterprise. Amanda backs up terabytes of Vyatta’s data spread across web sites, e-mail server, source-code repository, databases, and user files. Here is the full story.

Interview with Ray Zhu (Senior IT Manager at Vyatta) about his experience with Zmanda was published  in Inc. Magazine in December. Here are some interesting excerpts:

“We did not have a commercial solution before. We were a startup and, in the beginning, someone developed a script for backing up that supported Linux. As we grew, we realized we needed to have something more scalable. Before, every time we had to add a new server, we had to have a developer write a new script. We needed to have something more manageable. “

“We went with Zmanda because it met the criteria. It supports all the flavors of Linux. It’s got a beautiful GUI interface. And it’s able to recover in a few hours. The results have been beautiful. We have nothing to complain about. What I need to do is once in a while look at the dashboard. If it is red, then something is missing. If it’s green, then it’s working. Now when we add a new machine, I can just go the Web-based GUI and type the server host name, which directory we need to back up on and which schedule. The interface is designed in an intuitive way based on what we want to back up and to where and when we want to back up. We have done quite a few tests and we’ve recovered all the machines each time. “

OpenSolaris, ZFS and Amanda

Wednesday, September 24th, 2008

I attended OpenSolaris Storage Summit last weekend.  There are lot of efforts going on to make OpenSolaris into a feature rich storage operating system. Some of the projects that are relevant to backup are NDMP, Storage de-duplication, Virus scanning, Disk encryption and ZFS hybrid storage pools.

I talked about Amanda network backup and recovery and how well it fits with OpenSolaris and ZFS plans. Amanda can backup ZFS filesystems taking advantage of ZFS snapshots. ZFS snapshots provides the ability to backup open files in Open Solaris. Amanda 2.6.1alpha OpenSolaris packages that are available for download takes advantage of this feature.  Amanda can also take advantage of ZFS send/recv functionality to do block level backups. Amanda provides users flexibility of backing up ZFS filesystems at file level  as well as block level using ZFS send/recv feature.

ZFS storage is an excellent target for Amanda backups. ZFS’s ease of administration, robustness and scalability makes it an ideal target for disk based backups.

Joe Little of Stanford University has written a blog on how to backup ZFS filesytems using Amanda to Amazon S3.

BTW, ZRM of MySQL already supports Open Solaris and takes advantage of ZFS snapshots for backing up MySQL.

PowerReviews: A Zmanda Success Story

Monday, September 22nd, 2008

If you are shopping for a backpack for an upcoming trip to Yosemite this fall, chances are you may head over to REI.COM or to compare various options and buy the backpack of your choice. On these websites you will also run into extensive reviews to help guide your decision. These reviews are powered by PowerReviews – a fast growing company which provides a platform for online retailers to quickly add consumer reviews functionality to their websites.

When PowerReviews started looking for a backup solution to protect rapidly growing critical data in their environment, they turned to Amanda Enterprise. Today Amanda Enterprise protects 30 Windows and 16 Mac OS X Clients in their environment. Here is the full story.

Simplify storage provisioning for backup to disk with Amanda using Solaris ZFS

Wednesday, September 17th, 2008

First, the announcement. On September 21st at 11:30am our VP of engineering Paddy Sreenivasan will talk at OpenSolaris Storage Summit in Santa Clara about Open Source backup software Amanda for OpenSolaris.

Now the news. Sun just published Sun Fire x4540 as Backup Server for Amanda Enterprise backup software quick-start guide on BigAdmin system administration portal. The guide provides an introduction to configuring the Sun Fire X4540 server as a backup server for backup to disk. The specific examples for configuring the zpool and ZFS file systems on the Solaris 10 illustrate how easy it is to provision high-capacity storage for backup to disk. The Zmanda Recovery Manager for MySQL quick-start guide for X4540 is going through a review and will be published soon as well.

Almost 75% of Fortune 1000 use backup to disk, which requires a lot of capacity. According to the latest ’08 survey by TheInfoPro of storage administrators working for Fortune 1000 firms, the provisioning continues to be the most time consuming activity, see the figure below:Time spending by storage administrators

Ease of provisioning of ZFS volumes with Sun Fire x4540 will be very welcome by many practitioners of backup to disk. For example, right now we are implementing backup to disk for our customer who is the world’s largest supplier of innovative flash memory products. The provisioning of storage for backup is a challenge for their 48 TB of EDA data kept on Solaris servers.

The storage administrators who invest in an easy to use, affordable and scalable (both in capacity and network bandwidth) backup appliance utilizing Amanda Enterprise on x4540, will spend almost no time provisioning storage. I am sure they will find creative ways to spend their free time!
