Stack Overflow is, “a question and answer site for professional and enthusiast programmers.” And those professionals and enthusiasts have been enthusiastic about it, with 12 million unique visitors over the past month, according to Quantcast, making it the 165th most visited site in the U.S.
Stack Overflow, and the other 100+ sites that are part of Stack Exchange let people post questions for others to answer. Users can vote on the best answers and the person who posed the question can state which answer was best for them. The questions are rarely simple, and usually involve detailed scenarios covering technical issues developers run into.
Recently Nick Craver, a software developer for Stack Exchange, posted on his blog some data on Stack Exchange’s traffic for a single day, and the hardware used to support the sites.
In keeping with the way Stack Exchange operates, we decided to post our own question and answer about how Zetta’s enterprise cloud backup solution could be deployed to protect Stack Overflows high-performance IT environment:
Q: What would it take to back up Stack Exchange using Zetta DataProtect?
A. To answer this question, let’s look at four areas: the amount of traffic and WAN capacity, the servers and storage that are being used, how Zetta would back these up, and the cost for backup.

According to Symantec, service providers will no longer be able to sell Backup Exec.cloud subscription licenses or renewals for Backup Exec.cloud as of January 6, 2014. Existing customers will be able to utilize the product until the end of service availability on January 6, 2015 or the end of their current term (whichever comes first). After January 6, 2015, customers and partners will not have access to the service, data or technical support.
So, that’s why we’ve decided to offer a migration offer for businesses affected by Symantec Corp.’s Backup Exec.Cloud shutdown:

The presentation above and post below were originally developed by Rich Webster, Zetta’s Director of Operations, who has 20+ years of exerience protecting enterprise IT envrionments at such companies as Netscape, eBay, and Shutterfly.
IT disasters happen every day, in every company. With the right preparation, no one ever hears about them. Without it, these disasters can make the evening news. The key to any DR effort is realizing that disasters in the IT business will happen and if the IT staff has done its due diligence, users will not know that anything was wrong.
IT Disasters come in a multitude of flavors. This can be defined as anything from the loss of network connectivity to the loss of a data center. The simplest components are often the culprits: Datacenters don’t normally go down, power supplies do. Network providers don’t normally go down, NIC cards do. Fortify yourself against the small issues and you will have protected yourself against 90% of issues that may impact your customer base.

Having Network Attached Storage (NAS) can be a lot simpler than backing up a large number of individual user machines, however, the rules for NAS cloud backup may be different then you’re used to. Each NAS vendor has its own particular steps to follow. Here is how to back up NetApp devices with Zetta DataProtect. If you need to back up another type of NAS, contact us at 650-590-0967 or by email – mailto:email@example.com.
NetApp Backup Basics
Zetta’s NetApp backup works by reading a user generated configuration file which defines the data sources to back up and the appropriate login credentials to gain access to these data sources.
When the config file is read by Zetta, network mounts will be created to the defined data sources and the ZettaMirror agent triggers a snapshot on the NetApp appliance which is used to capture a consistent state of the NetApp file system and replicate the targeted data to the Zetta cloud. The ZettaMirror agent walks the directory tree, finds files that have changed and transmits the delta to Zetta. Once the transfer of data is complete, Zetta creates a snapshot of the file system on the Zetta storage end, deletes the NetApp snapshot and disconnects.
