With NetBackup 7.5 now on the horizon, it's time to make sure you're aware of the coming end of support for NetBackup 6.x.  It's hard to believe it will have been seven years since the NetBackup 6.0 release!

On October 3, 2012, NetBackup 6.x will reach End of Support Life (EOSL).  This includes ALL 6.0 maintenance packs and 6.5 Release Updates.

The NetBackup 6.x EOSL means that in order to continue receiving NetBackup support, an upgrade to NetBackup 7.x will be necessary.

Version 7.1.0.3 is the latest available update today.  (The 7.1.0.4 maintenance release is expected to see release in March.  It is expected that this will be the final 7.1 update.)

In March 2012, NetBackup 7.5 GA will also be available as an upgrade path.

There is no cost to upgrade for customers with a current maintenance contract; however, you may find that additional or updated hardware is needed. Use...

PostgreSQL (commonly referred to as Postgres) is a powerful, open source object-relational database system. It is used by several prominent users including the International Space Station, Skype, Reddit, and Yahoo!

In a blog post last year, Backing up the Dolphins, we had announced support for backup of MySQL via NetBackup. I'm happy to now be able to announce the availability of a Postgres Agent for NetBackup, certified and available from Zmanda, our STEP partner and a specialist in backing up open source databases.

Zmanda's NetBackup Postgres Agent was developed using the XBSA API provided by NetBackup. The NetBackup XBSA interface allows Zmanda to create, query, retrieve, and delete data objects using NetBackup for data storage. The operations on the objects use the rules...

It seems like businesses are looking at modernizing backup like it’s a trip to the dentist: too time-consuming and painful, and always costly! So they end up taking shortcuts, hoping that the cavity of data loss will never occur. But just as advances in dental techniques have taken much of the pain out of these visits, backup is finally experiencing a revolution of its own, thanks to new developments from Symantec.

Everyone knows what the problem is – it’s just too complicated. You shouldn’t have to feel like you’re performing root canal surgery in order to make sure you organization’s data is protected, and most importantly can be recovered. But that’s just how it feels when the amount of data that needs to be backed-up is growing so rapidly and as data centers grow ever more complex. The reality is that there are now so many physical and virtual systems crowding infrastructure that the average company has seven separate backup...

If you are evaluating dedupe solutions, the dedupe ratios claimed by dedupe vendors are bound to intrigue you.  I have seen claims of dedupe rates as high as 50:1 and I am sure there are claims of even higher dedupe than that. Are such dedupe rates realistic? Speaking truthfully, yes, but one must understand the assumptions and the math behind such high dedupe rates.  These dedupe rates generally have the following assumptions:

  1. Logical Capacity: Logical capacity is the amount of data one “would have” stored with no dedupe or compression. So for example, if you are protecting 20 TB of data for 30 days and if you are running daily backups, your total data protected data (in theory) is 20 x 30= 600 TB. In practice, for an environment with average change rate, backend dedupe capacity is equal to the front end capacity for a 30 day retention period. So assuming 20 TB of dedupe storage is needed, your dedupe ratio is 600/20 = 30:1. While this makes...

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...

I was recently asked, “Why would I buy a NetBackup appliance when I could buy the software and cheap JBOD?”

Initially, I was taken aback by the question.  However, after giving it more thought, I realized it was a fair question and an opportunity to explain the benefits of NetBackup appliances.

In responding to the question, I used the following analogy: 

My anniversary is coming up and do I:  make dinner reservations at my spouse’s favorite restaurant or decide to prepare the meal myself and we dine in?  Granted I can save some money by us eating in, and even skimp on the quality or cut of the steak, but what am I really saving?

To make an apples-to-apples cost comparison, the true costs of making dinner myself are the expenses and time to: 

  • Plan the menu
  • Create the shopping list
  • Shop (multiple stores:  groceries, wine, flowers)...

I'm very pleased to announce that our first Maintenance Release for NetBackup 7.1 is now available!

7.1.0.1 Download Links
 http://symantec.com/docs/TECH158802

This is a MAINTENANCE Release (as opposed to a Release Update) - it can ONLY be applied on top of NetBackup 7.1.  (If you are running 7.0 or 7.0.1, you will need to upgrade to 7.1 before you can apply 7.1.0.1.)

Today, MySQL powers some of the largest websites in the world.  If you are storing production data in MySQL, having a formalized and tested MySQL backup strategy and implementation is crucial.  I can't tell you how many times I have been asked when NetBackup will support live backups of MySQL, but I do know it's happened a lot!  That's why I am delighted to announce that now, we can tell you that we DO have that support.  We worked with Zmanda (www.zmanda.com), a well known MySQL backup specialist - AND a Symantec STEP Partner! - to create a MySQL agent for NetBackup which is now available!

The agent is created by integrating NetBackup with Zmanda Recovery Manager for MySQL.  The product and integration are described at http://www.zmanda.com/netbackup-mysql-backup.html.  This integration allows for seamless backup of MySQL servers in...

NetBackup RealTime iconOne of the more intricate details when discussing CDP is how all the data is actually stored inside the CDP product.  NetBackup RealTime is unique in the sense that it has a patented reverse-journal that stores data differently than other CDP offerings.  The best way to explain it is with an example.

Let's say you have a 1TB application of some kind and over the course of time you have the following 3 changes:

  • Change 1, 100GB
  • Change 2, 100GB
  • Change 3, 100GB

 

This is a mass simplification since CDP works at a block level so these changes would not really be 100GB but something like 4k blocks.  I'm assuming that change 1 came in first, followed by change 2 and finally change 3 (in that order).  So after these 3 changes the app is now 1.3TB in total.

Most CDP products will take the initial full...
