Eliminating the Effects of Application Stun

Application stunning during the snapshot process is a topic that often bubbles up in customer conversations on data protection for VMware environments. To level set, application stun goes hand-in-hand with any snapshot operation. VMware stuns (quiesces) the virtual machine (VM) when the snapshot is created and deleted. Cormac Hogan has a great post on this here. Producing a snapshot of a VM disk file requires the VM to be stunned, a snapshot of the VM disk file to be ingested, and deltas to be consolidated into the base disk. If you’re snapping a highly transactional application, like a database, nasty side effects appear in the form of lengthy backup windows and application time-outs when the “stun-ingest-consolidate” workflow is not efficiently managed. When a snapshot of the base VMDK is created, VMware will create a delta VMDK. Write operations are redirected to the delta VMDK, which expands over time for an active VM. Once the backup completes, the delta VMDK needs to be consolidated with the base VMDK. Longer backup windows lead to bigger delta files, resulting in a longer consolidation process. If the rate of I/O operations exceeds the rate of consolidation, you’ll end up with application time-outs.Rubrik was designed…

New vRealize Orchestrator Workflows for Enhancing Your Rubrik Experience

One of my favorite topics of discussion is hearing how folks are embracing the world of Rubrik’s Converged Data Management to tie in our RESTful APIs with other systems for end-to-end automation. One such system is VMware’s vRealize Orchestrator (vRO) which was released as a community focused project on Flowgrab over half a year ago. Since then, we’ve added a lot more to the product across two major releases, such as replication, new form factors, and a plethora of user experience enhancements. This has a direct correlation on our API maturity in terms of functionality, available resources, and what can be done to the data protection fabric. I’m here to share the next evolution of our vRO Plugin. Our very own Matt Altimar, who has over a decade of experience as a Senior Server Administrator building and maintaining large enterprise data centers, has constructed a new open source project on GitHub with a ton of new Rubrik workflows. These are all compatible with release 2.0 of our product and sync up nicely with a vRO deployment. If you’re looking to expose workflows like SLA Domain assignment, on-demand backups, mount removal, and much more – you have to check out this project! Getting started…

Meet Cerebro, the Brains Behind Rubrik’s Time Machine

Fabiano Botelho, father of two and star soccer player, explains how Cerebro was designed. Previously, Fabiano was the tech lead of Data Domain’s Garbage Collection team. Rubrik is a scale-out data management platform that enables users to protect their primary infrastructure. Cerebro is the “brains” of the system, coordinating the movement of customer data from initial ingest and propagating that data to other data locations, such as cloud storage and remote clusters (for replication). It is also where the data compaction engine (deduplication, compression) sits. In this post, we’ll discuss how Cerebro efficiently stores data with global deduplication and compression while making Instant Recovery & Mount possible. Cerebro ties our API integration layer, which has adapters to extract data from various data sources (e.g., VMware, Microsoft, Oracle), to our different storage layers (Atlas and cloud providers like Amazon and Google). It achieves this by leveraging a distributed task framework and a distributed metadata system. See AJ’s post on the key components of our system. Cerebro solves many challenges while managing the data lifecycle, such as efficiently ingesting data at a cluster-level, storing data compactly while making it readily accessible for instant recovery, and ensuring data integrity at all times. This is what…

Restoring Entire Virtual Machines in 6 Seconds with Rubrik’s Instant Recovery Technologies

Data protection is an insurance policy used to guard against loss, corruption, and failure. Because of this, I’ve often said that the true measure of any backup solution is the ability to restore data. After all, backups that can’t be restored aren’t really worth that much to you and your team, right? There are a number of quantifiable methods for putting your eyeball on the ease of a restore, with search time, recovery time, and overall simplicity of the workflow coming to mind. The amount of moving parts involved to restore data have a direct and exponential effect on restore times. Because most all solutions require combining disparate storage and software together, many of the top solutions in the Gartner Magic Quadrant require 10 – 30 minutes to restore pieces of data. This is measure from the start of the request to the end of the workflow. That seems like an incredibly long time and there are a number of reasons for it. Other solutions have to hydrate data, transfer it from one media to another, and are using write-optimized storage volumes for restores (this doesn’t work very well). Enter Rubrik: a converged data management stack that uses a combination of flash…

ExponentHR Goes Forward with a Simpler, Easier DR Strategy

Misha Vyazmensky, CTO, and Chris Gurley, Sr. Network Engineer, explain how Rubrik helped ExponentHR move forward in its DR strategy. What does ExponentHR do? Misha: Since 2001, we’ve been a leading human resource information systems SaaS platform. We help businesses (100 to 10,000+ employees) drive smarter decision-making, from running payroll to accessing vast amounts of data for financial analysis to managing employee benefit plans in light of recent legislative changes like ObamaCare. Why were you investigating a new solution for backup and replication? Misha: We have a team of 4 employees. We’re a small group supporting an enterprise-level business so we place a high emphasis on technologies that deliver simplicity and ease of management. Chris: Before, we were using a virtualization-centric backup solution that had replication capabilities to deliver off-site availability. When it worked, it was fine. When it didn’t work, it was rocket science to root cause the issue. Restores were also click-intensive and time consuming – it took a hundred clicks and 30 minutes to start restore for just 50 VMs. Why Rubrik? Chris: We were two days away from signing paperwork to expand our existing backup system when I saw Duncan Epping’s post on Rubrik. We had…
