Zen Innovations: Manual scripts to Amanda Our initial manual processes, scripts and cron jobs quickly started to get complicated as we grew our infrastructure. We needed to do backups regularly and be in a position to recover quickly without too much manual intervention. Our initial approach was neither scalable nor suitable to work efficiently.

3Jane: We Backup Everything! We backup: All of our custom written source code Database schemas Dynamically generated website content Corporate e-mail data Other proprietary information Data is spread on all flavors of Fedora Linux as well as Windows 2003 and Windows 2008 Servers And oh, we also want to backup to Amazon S3 for Disaster Recovery.

Backup Scheduling: Traditional Approach 70GB Data Size You plan for this Server 1 60GB 50GB 40GB Backup window will be different for each backup run and there will be spikes in resource utilization during full backups Server 2 Server 3 Server 4 Server 5 30GB 20GB but you mostly use THIS Server 6 Server 7 10GB 0GB Sunday Monday Tuesday Wednesday Thursday Friday Saturday Zmanda: Open Source Backup www.zmanda.com Twitter: @chanderkant 12

Advantage of Open Open Formats Proprietary format for backup archives comes with huge cost and pain Backup on one platform and recover on another I m able to recover the system using basic Linux tar and gzip commands even without Amanda. When it comes to recovering data, you don t want a lot of dependencies. - Ray Zhu, Senior IT Manager, Open discussions! forums.zmanda.com wiki.zmanda.com Zmanda: Open Source Backup www.zmanda.com Twitter: @chanderkant 17
Perspectives of Zmanda Customers The cost-effective nature of Amanda Enterprise has allowed us to implement a single common solution for enterprise wide backup, while other solutions would have be price-prohibitive for our company in the current market climate Steve Jackson, Systems Architect, Haas Cabinet The administration via Zmanda Management Console, which handled all the set up and interaction with our tape stacker, helped to make our entire backup process very simple and it cut down on a lot of work for our systems engineer Sergio Laberer, Managing Director, Zen Innovations Every morning, I have peace of mind after looking at the Zmanda backup logs. Ray Zhu, Senior IT Manager, Vyatta The data is critically important to the company, and it needs to be protected from equipment failure and other risks,zmanda s engineers went out of their way to develop a solution that worked for us.
