In the data protection world, a number we frequently see and hear are deduplication rates. We hear of dedupe rates ranging from 50:1, 20:1, to 10:1. Recently, I heard someone say that 50:1 is 5 times better than 10:1.  Their fuzzy math made me cringe, and I knew it was time to address this.       

To clarify deduplication rates, we need to examine: 1) the factors that influence deduplication rates and 2) the math. 

Deduplication Factors

Deduplication rates are like automobile miles per gallon (mpg):  Your Results Will Vary. The factors that affect deduplication results are:

  • Types of data (unstructured versus structured data) 
  • Change rate of data (what percent of data changes)
  • Frequency and type of backup (how often are you backing up the data? (i.e. daily, weekly, fulls or incremental)
  • Retention (how long are you keeping the dedupe data)

IDC approached Symantec, unsolicited, for a briefing on V-Ray. They were looking to create an Insight Report for their customers as they had so many inquiries around V-Ray. You’ll find this to be a very comprehensive and technical write up that shows NetBackup’s leadership in virtual machine protection with VMware and Microsoft Hyper-V.

Looking for the details on NetBackup for VMware?  Would you like to know about the nuts and bolts inside? We recently published, and we intend to publish more on technical details on award winning NetBackup for VMware protection. As there are many blogs in this series, I am publishing this blog as a container for this series.

The series so far:

Discovery job in VMware Intelligent Policy

Understanding V-Ray vision through backup process flow

Transport methods and TCP ports

Recently, one of our customers asked me if NetBackup for VMware supports the use of a dedicated data store for snapshots. That triggered this blog.

  Snapshot is great. Among many of its uses, NetBackup employs it to create a consistent point-in-time image of the virtual machine for the purpose of backup. When a snapshot is active, the writes to VMDK files are directed redo logs. At the end of the backup, the snapshot is released and redo log is played back into VMDK.

  The world is less than ideal. What happens if a backup ends prematurely and the snapshot is left behind? Now the redo log grows. What if such situations arise frequently? Now you have multiple redo logs growing in the data store. There are two major issues here.

  1. The storage space on data store gets used up quickly, if the data store fills up all the VMs using that data store would be affected
  2. The more snapshots you have for the same virtual...

As more and more of your business critical applications get virtualized, your data protection solution needs to step up to the plate. You are likely to have a hybrid environment and your data protection solution should have the visibility into what is inside both virtual and physical systems. Processor intensive blind deduplication of VMDK files will not scale as your environment grows. Above all, the solution also needs to protect vCenter server, the backbone of vMotion, DRS, HA and more.

We provided a technical deep dive on NetBackup for VMware and how this award winning data protection solution can be quickly deployed for protecting everything in your data center in a matter of minutes. Powered by V-Ray and Intelligent...

Welcome to the NetBackup 7.5 Pre-GA group.  This space will be a valuable area for sharing information about the new features of NetBackup 7.5.  Over the coming months there will be Beta and First Availibility information posted here to assist with testing and deployment of the signature features of NetBackup 7.5 and various other changes/improvements to the product and it's components.

Stay tuned for more!

It had been a while since my last blog on NetBackup for VMware. The next in line in that series was restore process flow. However, since there had been many questions on transport methods and TCP ports, let us talk about those for now. I will get to restore process flow soon!

Thus this blog is just an addendum to Understanding V-Ray vision through backup process flow.  As that blog was too long already, I didn’t spend much time explaining various transport types and TCP ports but I received so many questions on those. Sorry for the delay.

Let us examine the transport types and ports usage through the view from VMware backup host.

There are three unique ways a backup host can stream data from VM data store. They are SAN, hot-add and NBD transports.

SAN Transport

Symantec backup appliances provide many business value benefits. In my earlier two blogs, Realizing OpEx Savings with Symantec Backup Appliances and Realizing OpEx Savings with Symantec Backup Appliances – Part II  five (5) areas of  OpEx savings were identified: 

  • Acquisition
  • Installation and integration
  • System administration
  • Upgrades: software and hardware
  • Support/maintenance

In this blog, the final two areas of OpEx savings will be examined; Upgrades and Support. 

Upgrade and Refreshes

With any point solution, there are multiple components that will require firmware and/or software updates. A best case is two updates per component per year. ...

Symantec backup appliances provide many business value benefits.  In my previous blog, Realizing OpEx Savings with Symantec Backup Appliances,  five (5) areas of  OpEx savings were identified: 

  • Acquisition
  • Installation and integration
  • System administration
  • Upgrades: software and hardware
  • Support/maintenance

And the topic of Acquisition were examined.  The next two areas to examine are Installation/Integration and Administration. 

Installation/Integration

The area with the greatest savings is Installation and Integration.  Depending on your environment, the amount of time it takes to perform the tasks, and if professional services are used, the savings may run into the tens of thousands of dollars. 

An important point to note is the...

Symantec backup appliances provide many benefits over traditional build-your-own or point solutions.   The benefits may take the form of faster time to deployment, reducing risk, reducing planned and unplanned downtime,  improving staff efficiencies, or enhanced service level.   To quantify in terms of dollars and business value, these benefits must be translated into capital expenditures (CapEx)  and/or operating expenditures (OpEx).  At that point, you have the attention of management. 

When performing a financial analysis, there are several common questions:  what areas provide the savings, how are the savings calculated, and is it necessary to calculate the savings to the nth degree?  This blog and two subsequent blogs will address these questions and examine the areas that typically  provide the greatest benefits. 

How are OpEx savings calculated? 

Typically, to calculate...
