Nuts and bolts in NetBackup for VMware: Avoiding CBT penalty with NetBackup Accelerator
Let us start our technical deep dive with NetBackup Accelerator for VMware. Most of you already know that NetBackup Accelerator is designed to provide full backups for the cost of performing an incremental backup. In this case cost stands for the backup window, backup storage, client CPU, client memory, client disk I/O, network bandwidth etc. required for running backups.
Netbackup Accelerator & backup/duplications
Hi all, We are the proud owner of 4 NBU appliances (2 x 5230 on PROD site and 2 x 5330 on DR/DEV site, these 2 sites are running OptDup from PROD to DR). We recently bumped up the storage on the 5330 appliances and I'd like to configure them to utilize Accelerator and get the best dedup rates possible. We have an SUG with the 2 x 5330, set with Failover - the problem we had would be the appliance in the top order would fill u,p and then backups would happen on the second appliance. This caused some servers that rely heavily on Accelerator to work its magic (eg on slow / small WAN bandwidth) to perform backup on an appliance (the second one in this case) where the track log doesnt exist/not updated and backup would run really, really slow then.....I hope that makes sense. I'm hoping to tackle this issue by either : 1) Creating multiple copies of the backup via SLP - 2 copies to be exact, each going to an 5330. My concern with this is that I found a technote that says (to my understanding), that this might not work : https://www.veritas.com/support/en_US/article.000024910 OR 2) Creating one copy of backup via SLP to one 5330, and afterwards create a duplicate of that copy to the other 5330. My concern with this is that I'm not sure whether Accelerator/track log would be created on that media server doing the duplicate. Just wanting to know if anyone has ever attempted to do something similar, and if so, how? My goal is to ultimately have an Accelerated SUG containing 2 x 5330 that will both be able to be used by an Accelerated backup client interchangeably without performance impact even if last full backup was done by one and the next one done by the other. My master server is a Windows 2008 R2, and all the media servers are the appliances (2x5330 and 2x5230) as mentioned above, all having NBU 7.7.3 Thanks SueFrequently Asked Questions on NetBackup Accelerator

NetBackup Accelerator transforms the way organizations do backups, I am compiling a list of frequently asked questions from NetBackup Community forums and providing answers.Nuts and bolts in NetBackup for VMware: What is new in NetBackup 7.6?
It had been a while since I added something new to this series on Nuts and Bolts in NetBackup for VMware. The dawn of NetBackup 7.6 is here. It is one of the biggest releases in NetBackup for VMware vSphere and vCloud. This release prepares for your journey to Software Defined Data Center. Are you ready? Fasten your seat belts! First and foremost, let us put some perspective on the adoption of virtualization in data centers. Symantec and VMware have been guiding you in reaping the benefits of virtualization. It is happening in three phases. You are likely to be in one of the three phases in this exciting journey. IT Production: In this phase, you are looking save on capital expenses through server consolidation for general-purpose workloads. The key advantage here is to pool and abstract hardware resources for optimal utilization. NetBackup prepared you for this phase since NetBackup 6.5 in 2007, the very first official release of NetBackup with VMware specific features. VMworld judges awarded NetBackup with Best of VMworld in Data Protection and Business Continuity category. NetBackup was the first product to ever get this recognition. NetBackup is still the only product that has won or became the finalist in that category the most number of times. Business Production: This phase is about virtualizing business critical applications and reducing operational expenses. Automation is the mantra at this stage. NetBackup prepared you for this phase since NetBackup 7.1/NetBackup 5220 release in 2011-12. Symantec V-Ray, VMware Intelligent Policies, SAN based offhost backups and integrated VMware Ready backup appliances mitigated the operational costs of virtualized workloads through simplification and automation. NetBackup 5220 and Symantec V-Ray got the attention from both VMworld and Microsoft TechEd judges bagging several awards. Software Defined Data Centers: This is the nirvana for virtualization where compute, network and storage is virtualized and managed as a service model. This phase is all about agility and efficiency for data centers. Now NetBackup 7.6 is preparing you for SDDC in 2013-14. So how exactly is NetBackup 7.6 preparing for this third phase in virtualization so as to reach software defined data centers? Let me give you an overview here. You are zero miles away from these features once you enter the 7.6 freeway to Software Defined Data Center NetBackup Accelerator for VMware workloads: Super fast backups for workloads in VMware vSphere and vCloud are here! NetBackup Accelerator for VMware combines three key technologies to deliver fast and resource efficient backups for virtual machines and applications. NetBackup Replication Director for VMware workloads: Storage array level snapshots and replicas can meet high RPO/RTO required for business critical workloads. However the lack of content awareness limits their use cases. NetBackup Replication Director for VMware vSphere and vCloud workloads enables you to make use of storage level snapshots and replicas without losing end-to-end content visibility, granular recoverability and data life cycle manageability. NetBackup Instant Recovery for VMware: This capability enables you to bring up enterprise grade virtual machines and workloads right from the backup storage even before restoring data back to production storage. NetBackup for VMware vCloud: NetBackup 7.6 brings unmatched support for VMware vCloud Suite, starting with end-to-end support for vCloud Director based environments. As you guys know, vCloud Director is the current foundation for building an SDDC for VMware customers. You get to protect the “DNA” of such SDDCs through NetBackup 7.6. Almost all features in NetBackup for VMware vSphere now seamlessly work for vCloud Director based environments. NetBackup Blue Sky Recovery: NetBackup now automates the migration and disaster recovery of physical machines into virtual machines in VMware vSphere and vCloud environments from the backups. NetBackup Auto Image Replication works in conjunction with this capability to take systems anytime to remote locations or to the cloud. This feature is designed to accelerate your journey to virtualization. Well, this is just an overview. We will get into the nuts and bolts of each of these features in upcoming blogs in this series. The first one in this series is already live. Here is the blog on technical deep dive into NetBackup Accelerator for VMware. Got a question NetBackup 7.6 for VMware features? Ask me using the comments section below. I shall answer them directly or through subsequent blogs. We have a lot to talk about in NetBackup 7.6!

Thanks to everyone who supported my earlier blog on Frequently Asked Questions on NetBackup Accelerator. I have received a number of follow up questions (as comments) in that blog and I had been answering them as time permits. Two recent questions needed some elaboration.NetBackup Accelerator questions the value of storage-based snapshot integration from Competitor ‘C’
Data protection is to meet recovery point objectives (RPOs) and recovery time objectives (RTOs) of an organization’s information. Traditional wisdom states that mission critical applications require data protection methods delivering superior RPO (the less is the amount of data lost during recovery) and RTO (the faster to recover). A data protection solution may provide one of more methods to deliver different tiers of RPOs and RTOs. In general, methods for establishing RPOs and RTOs improve in the following order… Streaming backups < storage snapshots < continuous data protection This is the story of a vendor promoting themselves as the advocates of storage snapshots. Symantec’s social media policy teaches me to be discreet and respectful of the competition. Hence let me refer to this vendor as Competitor ‘C’. This Competitor ‘C’ had been scoring brownie points from some leading analysts by telling the story of storage snapshot based data protection. The story is primarily enhanced by a broad list of storage vendors they are currently supporting for storage-based snapshot management. NetBackup had been supporting storage snapshots for over a decade. It had been available since the release of NetBackup 4.0V when ServerFree Agent and Array Integration Option (later absorbed into NetBackup Snapshot Client) were introduced. The second generation of storage snapshot management started with NetBackup 7.5 when NetBackup Replication Director was brought to the market. Obviously, we position NetBackup Replication Director to protect environments requiring superior RPOs and RTOs. Recently Symantec commissioned Principled Technologies to put NetBackup and three other competitors to the test. The goal was to evaluate all four backup solutions for scalability and performance in meeting RPOs and RTOs. The first official report for NetBackup vs. Competitor ‘C’ for the battle of kingdom for scalability and performance is already published here. NetBackup Replication Director outperforms the storage snapshot solution from Competitor ‘C’ by a wide margin. While this is great news for us, we were rewarded with even better, somewhat earthshaking news! Are you ready? Let us consider a VMware vSphere environment with 1000 virtual machines. 400 of those virtual machines are hot with business critical applications like Microsoft Exchange, Microsoft SQL Server and Microsoft SharePoint running. Principled Technologies is simulating real world workloads by loading these applications with programs designed to induce heavy activity. The remaining 600 virtual machines are hosting web applications with programs simulating real world web traffic. We want to create application consistent recovery points for the entire virtual environment. Let me list the results and some key observations. NetBackup Accelerator questions Storage Snapshots from Competitor 'C' Storage snapshots managed by Competitor ‘C’ Storage snapshots managed by NetBackup Replication Director NetBackup Accelerator based streaming backup Time required for backup (The best RPO possible for the environment) 1000 VMs in 2 hours 50 minutes 21 seconds 1000 VMs in just 38 minutes and 22 seconds 1000 VMs in 2 hours 51 minutes 33 seconds Compatibility Storage array vendor dependent snapshot Storage array vendor dependent snapshot Works with any production storage including DAS. NAS, SAN and converged infrastructure Implementation Requires professional services Professional services not required, but storage array knowledge recommended Single Click on backup policy user interface!

Always make sure to verify the compatibility of storage array, array firmware, array management software, backup software plugin etc. before implementing changes Training recommended. Always make sure to verify the compatibility of storage array, array firmware, array management software, backup software plugin etc. before implementing changes This is as simple as it gets! No dependence on storage hardware. Protection against array loss Need to create backup copies from snapshots, additional time and resources needed. Need to create backup copies from snapshots, additional time and resources needed. Full protection against array failures as full recovery points are available in backup storage Protection against site loss Need to maintain similar storage systems offsite Need to maintain similar storage systems offsite Any storage can be used offsite, including commodity storage So what is the earthshaking news here? NetBackup Accelerator provides the same level of RPO for your business applications for which Competitor ‘C’ would have required storage vendor dependent, expensive, high maintenance array snapshots! It is time for industry analysts with withdraw brownie points truly based on how many arrays a data protection vendor supports, but rather look at how a vendor supports business needs of customers with simplicity, agility and performance.
