+0 Vote Up -0Vote Down

Normal 0 false false false EN-US X-NONE X-NONE

As we continue to see MySQL being implemented in bigger and more challenging environments, we are working to ensure Zmanda Recovery Manager for MySQL (ZRM) matches this growth and provides a comprehensive, scalable backup management solution for MySQL that can easily integrate into any network backup infrastructure.

The latest release of ZRM for MySQL is a significant next step, bringing disk space and network usage optimization and enhanced backup reporting, along with simplified management to help configure backups quickly and intelligently.   Additionally, ZRM for MySQL 3.5 now supports backup of MySQL Enterprise Edition, MySQL Community Edition, SkySQL, MariaDB, and MySQL databases running on latest versions of Red Hat Enterprise Linux, CentOS, Debian,

Zmanda - A Carbonite Company
+0 Vote Up -1Vote Down

I am very excited to share that today Zmanda has combined forces with Carbonite - the best known brand in cloud backup. I want to take this opportunity to introduce you to Carbonite and tell you what this announcement means to the extended Zmanda family, including our employees, customers, resellers and partners.

First, we become “Zmanda - A Carbonite Company” instead of “Zmanda, Inc.” and I will continue to lead the Zmanda business operations. Carbonite will continue to focus on backing up desktops, laptops, file servers, and mobile devices. Zmanda will continue to focus on backup of servers and databases. Carbonite’s sales team will start selling Zmanda Cloud Backup directly and through its channels. Since Carbonite already has a much larger installed base of users and resellers, our

As MySQL continues to grow (as a technology and as an ecosystem) the need and importance of creating and deploying robust MySQL backup solutions grows as well. In many circles Zmanda is known as “The MySQL Backup Company”. While we provide backup of a wide variety of environments, we gladly take the label of backing up the most popular open source database in the world, especially as we kick off our presence at the 2012 MySQL Conference.

Here are some of the updates to our MySQL backup technologies that we are announcing at the conference:

Zmanda Cloud Backup adds Tokyo as its latest cloud storage location
+1 Vote Up -0Vote Down

We are adding support for Asia Pacific (Tokyo) Region in Zmanda Cloud Backup (ZCB). This is the fifth worldwide location supported by ZCB.

This support provides faster uploads for ZCB users in Japan. Throughput will be significantly higher because of less hops along the way and very high bandwidth connections typically available in Japan. Overall processing will be faster because of lower latency (expected to be single digit millisecond latency for most end users in Japan).

Taking a Snapshot of a Thousand Dancing Dolphins
+1 Vote Up -0Vote Down

An increasing number of large MySQL applications, e.g. social networking and SaaS back-ends, use a distributed MySQL architecture. MySQL data is distributed logically or heuristically on multiple, and in some cases thousands of, real or virtual servers. Backing up such large and dynamic environments presents its own complexities.

In this blog, we will use the cluster terminology - but we do not imply that NDB Cluster storage engine is being used for MySQL. Most implementations use InnoDB for data and MyISAM for dictionary. Typical architecture for such applications uses Database Sharding - i.e. shared-nothing partitioning of data across similarly configured nodes.

In most sharded environments, high availability is built-in - i.e. the cluster can continue to answer the queries and commit the transactions of all users in face of a node failure. This is typically accomplished either by

Fast Backups of MySQL Running on Amazon EC2
+2 Vote Up -1Vote Down

If you are running your MySQL databases on the Amazon EC2 compute cloud, Zmanda Recovery Manager (ZRM) for MySQL can perform fast full backups of these databases by using Elastic Block Store (EBS) Snapshots. ZRM takes only a momentary read lock on the MySQL database during the creation of the snapshot, in order to ensure consistency of the backed up database archive. MySQL Backups using Amazon EBS snapshots are differential backups, meaning that only the blocks that have changed since your last full backup (via EBS snapshot) will be saved. For example, if you have a database with 100 GBs of data, but only 5 GBs of data has changed since your last snapshot, only the 5 additional GBs of snapshot data will be stored back to Amazon S3 during the current full backup run.

ZRM automatically

Windows XP -> Cloud -> Windows 7
+0 Vote Up -0Vote Down

We recently added support for Windows 7 to both Zmanda Cloud Backup and Amanda Enterprise. Zmanda Cloud Backup stores its backup archives on the Amazon S3 Storage Cloud. Amanda Enterprise has the option to do so. Users can backup both the Windows file systems and system state, as well as various Microsoft applications, Oracle and MySQL databases. Now we support all Windows versions supported by Microsoft, including Windows 7.

To upgrade from Windows XP to Windows 7, Microsoft recommends users to backup their Windows XP to external hard disk and then install Windows 7. Backup to (and Restore from) Cloud offers another

Our price increased today. Now we are one-tenth the cost of Symantec.
+2 Vote Up -7Vote Down

Today we increased price for the Amanda Enterprise Backup Server. The new price for our Standard subscription level is $500 per year. Our online store is a place to quickly checkout prices for all our products on a single page. This price increase was done in conjunction with release of Amanda Enterprise 3.0, which represents several man years of R&D on the backup server, including advanced media management such as D2D2T. Our subscription provides access to software and enterprise-class support.

Amanda Enterprise is used by businesses of all shapes and sizes. But a typical scenario is the following:

Backup Zen
+0 Vote Up -1Vote Down

One of the questions that comes up often in the Backup world is “Why can’t I just write a script to do this myself!?”. Well, as a do-it-yourselfer myself, the answer is “Absolutely, a customized backup script can be written, and in fact, the first version of it won’t be that complicated to develop either”. However, a home-grown backup script can quickly become tedious to enhance and maintain.

Lets look at the progression of events following a decision made by a system administrator or a DBA to develop their own backup scripts. Lets take the example of Joe, a MySQL Database Administrator at an e-commerce company SuperWidgets:

1. January: SuperWidgets has been around for one year, and sales of their super widgets have been increasing. The CEO of SuperWidgets, Mary, has faced serious consequences of

Cloud Backup II
+0 Vote Up -0Vote Down

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

Vyatta: From Homegrown Backup Scripts to Amanda Enterprise
+0 Vote Up -0Vote Down

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.

Oracle: Protected by Zmanda!
+0 Vote Up -0Vote Down

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 of Oracle

Scaling Up: MySQL on NetApp
+0 Vote Up -0Vote Down

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

A Snapshot of Snapshots
+0 Vote Up -0Vote Down

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

Protecting CFD (and making more money as a MySQL DBA)
+0 Vote Up -0Vote Down

No, this is not a blog about Computational Fluid Dynamics - my least favorite subject in college. This is about a more exciting (sorry mechanical engineers!) CFD: Customer Facing Data. This is the data that is typically available on the website of an organization that their customers interact with. CFD can range all the way from profiles of users on a social networking site such as Facebook to the customer information database of an e-commerce company such as Travelocity.

CFD represents today’s data protection challenge. Probably the biggest challenge while planning a backup solution for CFD is that it is very hard to figure out what to plan for. You might be starting with a very small database which might grow much more rapidly than what you think. If the data can be segmented based on users or some other characteristic,

Highly Scalable MySQL Backups using Snapshots (ZFS or NetApp)
+0 Vote Up -0Vote Down

We have been focusing on providing the best possible backup solution for following scenario: 100 GB+ of data stored in MySQL database, Transaction intensive workload (i.e. rapid rate of change of data), with a business requirement to be able to perform point-in-time restoration of the MySQL database. Oh, the solution also needs to take into account that the database can grow to 1TB or more very quickly.

For such a scenario, we believe that the best possible solution today is a combination of:

  • Storage level snapshots - a capability built into ZFS (Solaris), NetApp, LVM (Linux), VxFS, and VSS (Windows)
  • Transaction logs generated by MySQL
  • Point-and-click restore capability provided by Zmanda Recovery Manager for MySQL
  • Two reports came out today which go into nitty-gritty of above. First is a joint report written by NetApp

    Today Sun and Zmanda announced our agreement to deliver a comprehensive, global data backup and recovery solution for MySQL Enterprise subscribers. Starting April 1st, MySQL Enterprise customers will be able to purchase ZRM for MySQL directly from Sun worldwide.

    I think Zack’s comment in the press release captures the rationale for the deal:

    “Protecting corporate data through effective backup and recovery is one of the most crucial tasks for a database administrator, and it can be a complex undertaking — especially for today’s large Web-scale applications,” said Zack Urlocker, VP of products, Sun Microsystems database group. “MySQL users have told us that global backup and recovery is very important to them, and we are thrilled that we can now offer ZRM for MySQL as an easy-to-use solution for protecting all of

    Zmanda Recovery Manager 2.1 - Keep those MySQL Databases Zipping
    +0 Vote Up -0Vote Down

    Today we announced a significant enhancement to our Zmanda Recovery Manager (ZRM) for MySQL product. Here are major highlights of this new version (2.1):

    End-to-end support for Solaris: We have had increasing number of requests from customers for supporting Solaris. While we always protected MySQL databases running on Solaris, we needed customers to run the ZRM core engine on a Linux box. Now we are able to run the ZRM core engine on Solaris itself. So a pure Solaris shop can use ZRM without getting a Linux server. The coinciding of this support with MySQL’s acquisition by Sun was not a planned thing

    Congratulations to Marten and team on Sun’s acquisition of MySQL today! This is a billion dollar stamp of approval on the importance of the LAMP stack. This also gives another strong backing to the business model which involves giving one’s software away for free to up to 99+% of users!

    This announcement comes at an interesting time for Zmanda. Just last week we announced support for the Solaris platform for our Amanda Enterprise product line. With our industry leading MySQL backup solution, we now have full coverage of operating systems and database software from the new Sun!

    Data Protection for the LAMP Economy
    +0 Vote Up -0Vote Down

    The value of data stored in LAMP applications is increasing at an exponential pace. Indeed, the LAMP stack fuels an economy of its own - with its own currency, lingo and players. While e-commerce is the clear and present evidence of the LAMP powered economy, the currency for this economy is by no means just monetary. Value is manifested in many factors other than financial gains: personal reputation and legacy, karma points, creativity etc. The LAMP stack fires up innovation by enabling new ideas - you can quickly and cost-effectively prototype a concept which other’s may find bizarre.

    User generated content (UGC) is one key currency of the LAMP stack. UGC, even votes (ok, diggs) on other’s UGC store tangible and lasting value. While naming “You”, a proxy for UGC, the Time’s Person of the Year 2006, The Time magazine said: “It’s a story about community and

    One of our most important goals while designing a graphical interface for Amanda was to simplify the life of a backup administrator. We found existing backup products in the market to be unnecessarily complex to setup and manage. I (and rest of Zmanda team) believe that managing your backups should be simple.
