Nuts and Bolts in NetBackup for VMware: Handling Orphaned Snapshots
AbdulRasheed | 27 Oct 2011 | 17 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 | 25 Oct 2011 | 0 comments

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 Deduplication, NetBackup appliances are the building blocks for protecting data centers and remote offices of any size.

We talked about best practice implementation architectures as well as tips and tricks to get up and running quickly by leveraging...

Realizing OpEx Savings with Symantec Backup Appliances - Part III
Phil Wandrei | 03 Oct 2011 | 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...

Nuts and bolts in NetBackup for VMware: Understanding V-Ray vision through backup process flow
AbdulRasheed | 27 Aug 2011 | 6 comments

Now that we know how VM discovery job works for a VMware Intelligent Policy (VIP), let us move on to the actual backup job. The process flow described here is the same for both VIP and browse-and-select type policies unless specified otherwise.

As we did in the previous blog, let us assume that the NetBackup master server, media server and VMware backup host are three different systems.

  1. NetBackup Policy Execution Manager (nbpem) triggers a backup job once the policy, schedule, virtual machine combination is due and backup window is open. It works in conjunction with NetBackup Job Manager (nbjm), NetBackup Resource Broker (nbrb) and NetBackup Enterprise Media Manager (nbemm) to identify the resources (media server, storage unit etc.) for backup. This resource identification process is well detailed in NetBackup Documentation,...
