Encrypting all Backups vs. Job-Level Encryption with NetVault: Backup

Posted by Dawn renee Campbell on January 27, 2010

You have selected the encryption algorithm you are going to use with the NetVault: Backup (NVBU) Encryption Plugin and have decided whether to encrypt your primary or secondary backups, but now you are not sure if you should encrypt all of your backups or use NVBU 8.5’s new job-level encryption feature.  

Prior to NVBU 8.5, your only option was to encrypt all the backups for the NVBU Server or a Heterogeneous Client where the NVBU Encryption Plugin is installed, but NVBU 8.5 gives you the ability to only enable encryption for specific jobs.  Understanding the benefits of both options will help you choose the best strategy for your environment.  

Encrypt all Backups  

The NVBU Server or Heterogeneous Client should only be configured to encrypt all its backups when  

  • All the NVBU Plugins installed on the NVBU Server or Heterogeneous Client are compatible with the Encryption Plugin
  • All backups from the NVBU Server or Heterogeneous Client require encryption
  • Primary and secondary backups require encryption
  • Backups will be targeted to NetVault: SmartDisk (NVSD) devices for deduplication

For a list of NVBU Plugins that are not compatible with the Encryption Plugin, refer to the NetVault: Backup Encryption Plugin Release Notes.  

Job-Level Encryption  

Job-level encryption for primary backups is beneficial when  

  • Not all the NVBU Plugins installed on the NVBU Server or Heterogeneous Client are compatible with the NVBU Encryption Plugin
  • Not all backups from the same NVBU Server or Heterogeneous Client require encryption
  • Primary backups do not require encryption while secondary backups for offsite protection do require encryption
  • Primary backups are targeted to NVSD devices for deduplication

Storage Technology Predictions for 2010 – What’s to Come

Posted by BakBone on January 21, 2010

Andrew Martin, VP of APAC

For much of 2009, deduplication was the “buzz” technology in storage. We started seeing major adoption of deduplication across different business sectors and companies of varying sizes, from large enterprises down to SMEs, adopt the technology. In addition, we saw a move from deduplication specialist companies dominating the space to traditional storage and software companies (BakBone included) coming to market with their own deduplication offerings. Finally, we saw the soap-opera-like battle of two industry giants slugging it out to take control as the leading deduplication specialist, Data Domain.

So what’s going to be the storage buzz technology of 2010?

Unfortunately, I don’t see anything on the horizon about to explode into every IT department. I stand to be proved wrong, but I do not see a technology taking us by storm in 2010 in the way deduplication did last year.

Cloud storage is growing with many vendors aiming to get on the bandwagon, form alliances and drive IT departments toward their vision of how cloud should be adopted. However, I have spoken to many people about cloud storage: IT directors, government departments, analysts, journalists and systems integrators, and whilst cloud is becoming increasingly relevant, it seems that adoption of cloud based will still be steady with corporate companies, particularly experimenting with different providers to find out what, if anything, works for them.

Whilst cloud is going to continue to grow, my educated guess is that it won’t be the must-have storage technology of 2010.

I have seen one technology making a comeback – archiving. However, I don’t think we can refer to archiving as  something new; in fact, it is one of the oldest storage technologies around with HSM-type products being popular in the height of the mainframe days.

However, across Asia and beyond, many companies are expressing a renewed interest in spending money on archive and HSM-type products. This is not only for e-mail but also for applications like SharePoint and even for file-system data. In addition, we are seeing numerous startup companies come to market with new archive products. It is interesting to see startups cropping up in such an old arm of storage technology. However, these new companies are working on the next generation of archive technology. Products that understand and take advantage of server and storage virtualisation, that can classify data in many different ways and even build a repository of archived data that can be used for analysis by other applications. BakBone recently released NetVault: Archive in Europe (a “next-generation archive product”), and it has been fascinating to see the level of demand for us to launch this product in Asia.

For me, I wonder what the natural progression from archiving might be. I have wondered if there ever might be demand for a vendor to build a platform that can intelligently delete data; not secure deletion, there are many light utilities available that securely delete data. My vision is of a technology that can identify data based on strong preset criteria that can be permanently deleted without impacting compliance or inadvertently removing required/useful data.

We are always reluctant to simply delete data; however we know two things for a fact:

1 – The rate of data growth causes significant data management problems.

2 – We store and protect large volumes of data that we do not need and will never use again.

Deleting data sends a chill down the spine of most IT administrators and is something we just don’t do. The risk of deleting something critical outweighs the potential benefit of getting rid of the waste.

However, if intelligent file systems ever become a reality, then maybe a product that allows data to automatically be “thrown” into the waste bin could be in our future.

Podcast – City of Safford Goes on the Record about FASTRecover

Posted by Amber Winans on January 19, 2010

Derek Kruger, IT Supervisor, City of Safford

9 min 39 sec

In this podcast, BakBone customer Derek Kruger discusses the challenges he faced with his old backup solution and why he switched to NetVault: FASTRecover. He shares with us how FASTRecover helps keep the city’s financial databases up and running, how it has eliminated backup windows and how the product works quietly behind the scenes to keep Exchange and SQL data available for the employees and citizens of Safford.  “No one cares if you back anything up, all they care is if you can get it back to them when they ask for it,” Derek says.

Encrypting Primary Backup vs. Secondary Copy Backups with NetVault: Backup

Posted by Dawn renee Campbell on January 13, 2010

You have the NetVault: Backup Encryption Plugin installed and have selected the algorithm you want to use. Now you are wondering if you should encrypt your primary backups, your secondary copy backups, or maybe you are not even sure of the difference between a primary backup and a secondary backup.

In NetVault: Backup 8.5 (NVBU 8.5), a backup job can be split into two distinct phases: primary backup and secondary copy. The primary backup is the back up of the data stream to the targeted backup device, while the secondary copy is a duplication or data copy of the primary backup to a different backup device, which is typically for offsite protection.

Unencrypted Primary Backup vs. Encrypted Secondary Copy Backup

Prior to NVBU 8.5, your only option was to encrypt both the primary backups and the secondary copy backups, but starting with NVBU 8.5, you can encrypt your primary backups, just the secondary copy backups or both your primary and secondary copy backups. Understanding the difference between the primary backups and secondary backups will help you choose the best strategy for your environment.

Typically the primary backup is performed to local disk-based backup devices such as NetVault: SmartDisk (NVSD) devices, virtual tape library (VTL) or shared virtual tape library (SVTL) to enable faster restores while the secondary copies are targeted to remote disk-based backup devices or physical tape libraries whose tapes are stored offsite for disaster recovery purposes.

Security requirements will typically dictate whether both the primary backups and the secondary copy backups require encryption. For example, if security requirements only require backups that leave the corporate network (such as those stored on physical tapes stored in a remote location) require encryption, then only encrypting the secondary copy backups that target the physical tape library is required. However, if security requirements dictate that data must be encrypted while it transfers across the network and/or while it is stored on a disk-based backup device, even though the disk-based backup device is located within the corporate network, then encrypting both the primary backup and secondary copy backup is required.

Encrypted data does not deduplicate well; therefore, encrypting only the secondary copy backup is beneficial when targeting primary backups to NVSD devices that have the deduplication option enabled. This enables users to take advantage of both encryption and deduplication by deduplicating the primary backup and encrypting the secondary copy.

In my next blog, we will discuss the difference between encrypting all your backups and using job-level encryption.
