Roadmap_August 2009.png

According to published plans, the all-conquering LTO tape format has no future after LTO 6, which is expected in 2012. This is ridiculous and there must be a secret roadmap for LTOs 7 and 8.

The LTO tape format dominates the open systems tape business, is used increasingly by supercomputer customers and is making some inroads into the mainframe area via bridges such as those from Luminex or Fujitsu's CentricStore (ETERNUS CS) virtual tape library (VTL). Supercomputer users like Argonne and NASA Ames in the USA will have ten year roadmaps. They can generate 8PB or more of data a year and there is simply no alternative to tape for...

It was a big effort but we finally made it: PureDisk 6.6 (a.k.a. Darrieus) is out! It contains a bucket load of improvements::

  • Storage Pool Installer

  • New Administration User Interface

  • Context sensitive help

  • Remote office job progress information

  • Optimized deduplication for PDDO/VCB backups

  • Oracle Agent

  • Exchange Granular Restore

  • NTFS Special file type support

  • Virtual Synthetics

  • Storage Pool Consistency Checker

  • PureDisk Command Line

  • Multi Stream for Replication

  • Storage Pool Conversion tool (6.2 to 6.5 layout)

I won't go into detail regarding these since they are covered sufficiently in the documentation. Let's instead talk about a background process that's...

I always believe that the best salesman is a person who really believes that his product is the best.   One way to know about the product is to explore its features and its value for money.  I have been working in the Data Security Domain for quite some time now and have worked on many backup products.   Exploring different products has always been a fun.  In the previous organization that I was working, I got a chance to explore 3 best of the breed backup products.  My manager had asked 3 vendors to show the POC of these products.  One vendor presented and showed us a demo on IBM Tivoli, the other vendor showed us a presentation and POC on HP Data Protector and the third vendor showed us a presentation and POC on Symantec Netbackup. This is where I got the chance to know about the 3 best software’s that I knew of and it was time for us to decide the best software.  Our environment consisted of few Sun Solaris Servers running...

So It took a bit too long to get right, but VCB is a powerful tool to get your backups flying along.

Network congestions, poorly configured ports, old servers, all other known enemies of the Backup guys/gals are defeated with the move to Virtual Servers, and the use of VCB backups. 
Our setup is around 40 vm's and the strategy was get the oldest boxes that cant be decommed over to a VM.  Now boxes that would jam up our backup window are leading the pack.  We get speeds regularly around 45,000KB /Second.  This was a game changer in our environment, and with the incrimental backups now available I have no issues at all.   The other nice factor that helps our stats is the lack of partial backups.  It's an all or nothing game, and once you get it right, you have very few failures.  If you do have one its a snap shot jam up most of the time.   This is fixed quickly by logging onto your vmware infrastructure client, and...

                                               NOM FILTER WORKS BETTER
Hi everyone,

Here I am going to share my experience with the NOM 6.5.4 which is really addressed all the issues which were available till 6.5.3. The patch 4 for 6.5 is especially released to address all the NOM related issues. Here I am listing the important features that came with this release.

Features:

  • Previous release we were not able to get the job relationship, but with this release we are able to get the relationships between the jobs (Group the parent job with all its child jobs).
  • We are now able to send the reports as attachment (in CSV format) with this release.
  • I am not very familiar with NOM 6.5.3, but however 6.5.4 is simply superb and the filtering options are really built very well....

Protecting the VMware environment has its own unique set of data protection challenges. There are basically three ways to protect VMware: the guest OS method, the console backup method and the VMware Consolidated Backup (VCB) method. The guest OS method treats each virtual machine as a standalone server and backups take place as usual as if the virtual is physical server. The second practice is the console backup practice, in which virtualisation administrators back up the VMware ESX Server with no regard of the underlying virtual machines in the ESX environment. (There is a “free” product, ESXi, but it has no console, and requires add-ons to manage.)

VCB Backup requires VMware Infrastructure 3 (VI3) and initially SAN attached disk (iSCSI or Fibre Chanel) but now supports VMFS with local, JBOD, iSCSI and Fibre-Channel-attached disk, network file system (NFS) and virtual compatibility mode raw device mapping (RDM). The only mode not currently supported is physical...

Guys, go through the below menioned link. This site has many NBU scripts available for FREE.

Also scripts are available bat, ksh, sh, etc.

I have tried some of the scripts and turned out to be very handy.

I saw an analyst report the other day that predicts that in spite of the economic downturn companies, large and small will be spending the same, or even increased, amounts on backup and recovery in fiscal year 2010.

Huh?

To make matters more “huh-like”, this study found that the adoption of disk based technologies is accelerating. Actually, when you think about it this makes sense - disk based backup improves recovery capabilities, backs up virtual environments more effectively and eliminates or reduces the physical requirement (and security hazard) for tape transport.

Actually, it’s making more sense the more you think about it. Older backup solutions or older hardware is less effective, more administratively heavy, time consuming, costing money and effort; new hardware technology on the other hand is more efficient and with new software there is more opportunity to automate more. The automation of IT processes can improve overall IT...

Today organisations of all sizes are faced with managing their disk backup storage growth and improving the speed and ease of recovery of application data, all of which has led to increased complexity for IT administrators. Unfortunately, data protection solutions of old are failing to keep pace with this overwhelming data growth and complexity whereas new data protection solutions are trying to centralise on a single code base and common platform to deliver next generation data protection. The fact is: it just doesn’t work like that.

Next generation data protection solutions need to be complete, powered by disk, and centred on recovery - regardless of size. All organisations are required to protect data in the most efficient way to maximise time and resources - irrespective of size or location. But not only this, they are required to ensure service level requirements are consistently met and at the same time squeezed to improve backup windows and recovery time - all...

Nowadays, probably not so much. There was a time where a day or two of outage didn’t make a huge difference to businesses - unfortunately that was over 20 years ago. We now live in a “NOW” world where every second counts. Somehow, no matter what your size, you have to consider how to ensure that business-critical data is always protected and always available. How do you improve your Recovery Point Objective? Enter stage left: Symantec Backup Exec Continuous Protection Server.

Continuous Protection Server (CPS) combines Backup Exec data protection with replication technology and disk-based data protection to provide continuous fast and reliable data backup and retrieval. It does what is says on the tin: offering continuous data protection; giving you the ability to restore data at a granular level from points in time throughout the day. At the same time you can perform simultaneous backups of multiple servers; fully integrated with Symantec Backup Exec for...
