Sun Heats Up Cloud Storage

Today Sun announced the Sun Cloud, including its Sun Cloud Storage Service at CommunityOne East in New York. We announced our partnership with Sun on integrating all our three products: Amanda Enterprise, Zmanda Recovery Manager (ZRM) for MySQL and Zmanda Cloud Backup with Sun Cloud. In near future, our customers will be able to chose between Sun Cloud Storage or Amazon S3 as the destination of their backup archives. Also, users running critical application on the Sun Cloud Compute Service will be able to protect their data using Zmanda’s products.

Of particular interest to us is Sun’s approach to use open and well defined APIs for their cloud services. We …

Cloud Backup II

In my previous blog on Cloud Backup, I wrote about the solutions we offer to backup to the Storage Cloud (e.g. Amazon S3). In this blog I will talk about backup of cloud, i.e. backup of your applications running on a Compute Cloud (e.g. Amazon EC2).

Let’s say you are migrating some on-premises applications (e.g. a customer facing enterprise app), which are currently being backed up to a tape library, to the cloud (fig 1).

Clouds don’t have a notion of a local tape library. So, your current backup solution will likely not work after this migration.

So, where do you backup? Note that Compute Cloud vendors do not offer automatic backups. While they may offer storage redundancy features, e.g. replication and snapshots, these are not replacement for a complete backup solution.

You still need backup archives and a backup catalog for those …

Data Protection for Today’s Economy: Amber Road and Zmanda

Today Sun announced the new 7000 line (aka Amber Road) of open storage appliances. Amber Road runs OpenSolaris and ZFS on industry-standard x86 hardware and includes innovative management software developed by Sun’s FISHworks (Fully Integrated Software and Hardware) group.

Our engineers worked along with Sun’s technologists on Amber Road in Sun’s labs for past few weeks, and today we are announcing support for Amber Road with both of our products Amanda Enterprise and Zmanda Recovery Manager for MySQL.

Amber Road is another example of innovation and value created by combination of open source and open systems. Combine  Amber Road with Zmanda’s open source backup …

Vyatta: From Homegrown Backup Scripts to Amanda Enterprise

Vyatta 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.

Zmanda Recovery Manager for MySQL - Detailed Review by Linux Journal

This month’s (September 2008) edition of Linux Journal has an in-depth review of Zmanda Recovery Manager for MySQL (written by Alolita Sharma a veteran of Open Source). Oh, and we made it on the cover as well! If you are browsing Magazines section of your local bookstore, do look us up..

Oracle: Protected by Zmanda!

We announced support for Oracle today. Specifically, Amanda Enterprise now protects:

  • Oracle 11g on Windows
  • Oracle 10g and 11g on Linux and Solaris
  • Oracle Enterprise Linux

On Linux and Solaris, we took the approach of integrating Amanda with RMAN. Keeping with Amanda’s philosophy of using native tools as closely as possible, we allow Oracle DBAs to perform recovery right from within Oracle Enterprise Manager. Amanda takes care of restoring all files needed for a DBA to perform recovery specific to their need (e.g. table level recovery or point-in-time recovery).

For Windows, on recommendation from backup experts at Oracle, we integrated with their new VSS writer. This enables us to take quick snapshot …

Slides from Red Hat Summit “Open Source Backup” Presentation

Here are my slides used for presentation at Red Hat Summit in Boston last week:

Zmanda: Open Source Backup (.odp open office format, 1.7MB)

Red Hat Summit in full swing

The Red Hat Summit started today here in Boston. Based on the evening reception today, it is shaping up to be a pretty good show. I will be speaking at the show on Thursday, June 19, 2008 at 11:30 AM eastern time. I will discuss current state of open source backup as well as where things are headed. We also have a booth located towards the right side of the exhibit floor (by small meeting rooms). We are demonstrating Amanda as well as ZRM for MySQL. Do stop by if you are coming to the show!

Scaling Up: MySQL on NetApp

For many MySQL implementations scalability is a crucial requirement. Scaling on various dimensions: Size, Performance, Cost and DBA-Stress-Level.

While several factors impact the scalability of the database, underlying storage probably has the highest impact. You need to make sure that the storage will fill up the buffers fast enough to keep queries happy, and acknowledge the writes fast enough to keep transactions happy. You need to make sure that you can keep growing the available storage as your database grows - MySQL databases are particularly prone to collect more and more data. You also need to make sure that maintenance tasks such as backup, cloning, and application testing will scale gracefully with the size of your database.

Storage systems from NetApp are a great choice when designing for MySQL scalability. Administrators can expand storage on the go …

A Snapshot of Snapshots

Storage Snapshots are excellent tools in arsenal of a system administrator to create quick and consistent backups of their databases and applications. Snapshot is a “picture” of a filesystem at a point-in-time. In most modern snapshot implementations, this “picture” is not a full copy of the data, but rather a set of pointers to the data.

Here is a list of current industry leading snapshot technologies:

  • LVM Snapshots: Snapshot capability built into the Linux Volume Manager (LVM) - the default option on a Linux system.
  • ZFS Snapshots: Snapshot capability built into the ZFS filesystem on Solaris and OpenSolaris
  • NetApp SnapShots: A feature of the WAFL® (Write Anywhere File Layout) filesystem
  • Windows VSS: Volume Shadow Copy Service from Microsoft introduced in …
