A New Era of Post-Production Data Management Software

Solving legacy problems of backup to tape

By Jerome M. Wendt

Nearly every small, medium or large organization is heading down the path of adopting disk-based data protection as a way to solve their legacy problems of backup to tape. But what many of these organizations have yet to recognize is that as they adopt disk to store these post-production copies of data, a new opportunity is presenting itself. They now have the option to manage and leverage post-production data in ways that were never possible when on tape but now lack the tools to do so.

Nearly every organization is somewhere on the journey towards implementing disk-based backup. But that does not mean every organization is implementing it in the same way or using the same technologies. Some are introducing disk in lieu of tape as a backup target. Others are using disk-based snapshots while still others are using some form of replication. Some are even using a combination all of these forms of disk-based data protection.

Then as they store this post-production data on disk they are looking to optimize how this data is stored. This is leading most organizations to try to deduplicate this data whenever possible and then use replication to move the data off-site.

But now that organizations are storing all of this data to disk, they have both a new opportunity and a new challenge in front of them. The opportunity is they now have near-real time copies of production data on disk.

These post-production copies of data are at most 24 hours old and may only be hours, minutes or seconds removed from the production copy of data from which they were derived. As such, they are excellent candidates for use for testing, development and disaster recovery.

At the same time, the challenge is finding software that can do this "post-production data management." After all, it is one thing to create a backup, snapshot or set up a replication job for a particular set of production data. But it is quite another job to then manage the tens, hundreds or even possibly thousands of these copies of post-production data in such a way that they are useable and easily managed by an organization.

These requirements are making it evident that a new category of software, which I refer to as "post-production data management software," needs to emerge. This software needs to give organizations the ability to manage this post-production data in such a way that they may perform tasks like:

  • Minimizing or eliminating backup and recovery windows by ensuring that data is on the right tier of disk at the right time
  • Ensuring that these post-production copies of data (backups, snapshots, replicated) are deduplicated whenever possible to conserve storage capacity
  • Data is replicated locally or remotely so business continuity and disaster recovery can occur automatically with minimal need for setup or ongoing management

Already we are seeing these next generation types of post-production data management capabilities begin to emerge. This last week FalconStor announced its new RecoverTrac technology that is now part of its Continuous Data Protector (CDP) software. RecoverTrac's purpose is to help CDP's snapshots and replication features deliver real world, turnkey business continuity and disaster recovery functionality without requiring organizations to spend tens or hundreds of thousands of dollars and numerous man hours in order to deploy, test, implement and manage it.

InMage is another company that has also been doing something similar for some time. In a series of two blog entries I wrote a couple of years ago I covered how a Dr. James Tu, an Information Security Officer at a real estate company, was using InMage Scout's replication capabilities to replicate data between two sites. Then within Scout he was creating virtual mount points so he could use them to perform recoveries at the secondary site.

Yet possibly the most interesting entrant in this emerging space is a new company called Actifio. It has built its entire platform around this concept of post-production data management and has gone beyond just acting as a backup target, replicating production data or creating snapshots of production data. While it can perform all three of these functions (it can act as either a backup target or a production file system which replicates or takes snapshots of production data) its ultimate objective is to optimally manage the post-production data under its control.

Once it has these post-production copies of data in whatever form they take (backup, snapshot or replicated,) Actifio can then deduplicate this data, put it on the appropriate tier of disk for recoveries or replicate it offsite for DR.

What specifically makes Actifio unique is its virtualization technology to re-purpose a unique copy of all post-production data for each of the different operational requirements. Instead of the complexity and cost of multiple tools for backup, snapshot, deduplication, disaster recovery or business continuance, Actifio is a single solution that manages data through its entire life cycle.

In the next few years I expect almost every size company to complete the transition from tape-based backup to using some form of disk-based data protection. However once that transition is complete, these organizations are going to recognize that just having all of their post-production data stored on disk adds insufficient value to their organization.

Instead they will want the option to easily and centrally manage where this post-production data is placed to facilitate business continuity, disaster recoveries and even operational testing and development of production applications. It is for this reason that I believe that companies will rapidly move beyond just implementing disk-based data protection and that a new era of organizations wanting and needing software that automates the management and placement of their post-production data is dawning.

For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...
Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Our guest on the podcast this week is Jason Bloomberg, President at Intellyx. When we build services we want them to be lightweight, stateless and scalable while doing one thing really well. In today's cloud world, we're revisiting what to takes to make a good service in the first place. Listen in to learn why following "the book" doesn't necessarily mean that you're solving key business problems.
Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...
Right off the bat, Newman advises that we should "think of microservices as a specific approach for SOA in the same way that XP or Scrum are specific approaches for Agile Software development". These analogies are very interesting because my expectation was that microservices is a pattern. So I might infer that microservices is a set of process techniques as opposed to an architectural approach. Yet in the book, Newman clearly includes some elements of concept model and architecture as well as p...

Microservices, for the uninitiated, are essentially the decomposition of applications into multiple services. This decomposition is often based on functional lines, with related functions being grouped together into a service. While this may sound a like SOA, it really isn't, especially given that SOA was an object-centered methodology that focused on creating services around "nouns" like customer and product. Microservices, while certainly capable of being noun-based, are just as likely to be v...
An explosive combination of technology trends will be where ‘microservices’ and the IoT Internet of Things intersect, a concept we can describe by comparing it with a previous theme, the ‘X Internet.' The idea of using small self-contained application components has been popular since XML Web services began and a distributed computing future of smart fridges and kettles was imagined long back in the early Internet years.
Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...
