Deduplication Rates: not the end all.
Phil Wandrei | 22 Jan 2013 | 1 comment

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)

Nuts and Bolts in NetBackup for VMware: Handling Orphaned Snapshots
AbdulRasheed | 22 Jan 2013 | 20 comments

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...

VMware Protection using NetBackup Appliances: A Technical Deep Dive
AbdulRasheed | 20 Mar 2013 | 6 comments

Note: Please click here for a recent and updated version of this webcast

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...

Nuts and bolts in NetBackup for VMware: Transport methods and TCP ports
AbdulRasheed | 22 Jan 2013 | 36 comments

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

Realizing OpEx Savings with Symantec Backup Appliances - Part III
Phil Wandrei | 22 Jan 2013 | 0 comments

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...
