How To Deal With Backing Up Multiple Operating Systems

 Multiple-OS-BackupGuest Article by Patrick Jobin.                             

As Apple’s popularity continues to grow, there will also be an increased chance that any given company might have to manage multiple operating systems within their network. And when diversity increases, so does complexity and maintenance.

  • A typical organization today might have the following:

  • Windows laptops for travelling employees
  • Mac systems for marketing and graphic design
  • Robust, secure IBM iSeries servers to process transactions and manage inventory
  • NAS boxes, File Servers or Web Servers running Linux

From an operational standpoint, this is great since each function is hosted on a machine that’s well-designed for its intended purpose. But from an IT perspective, it can cause a lot of problems.

Let’s take data protection as an example.

In a Windows-only environment, you would only have to back up one set of computers every day using a single process. But now, you need to create a separate backup process for each system, so your daily backups could end up taking 4 times longer.

And there’s another danger. When it comes time to recover your company-wide systems in an emergency, the recovery process will also be 4 times more complicated, with 4 times the chances that a mistake could occur.

This gets even more complex as other databases and enterprise systems get added to the mix. (SharePoint, Lotus Notes, Oracle, etc...)

If your company is dealing with many diversified operating systems within the same network, you can simplify your IT management through 2 simple steps.

Step 1: Consolidate Expertise

The general tendency within organizations is to allow employees to create “knowledge silos”. One person might be a MAC expert, the other an IBM expert, and a third would be a Windows expert.

Instead, you should train your employees to be specialists across all systems... within certain fields. Using the data protection example, you would have one employee who is well trained in backup and recovery for each of the 4 operating systems listed above.

This way, when it comes time to recover the data, you don’t have to round up and coordinate a team of 4 people. Just a single person can do the job.

Step 2: Automate

Once you’ve consolidated all of the backup knowledge to a single employee, they’ll be better equipped to back up all 4 systems more effectively by eliminating wasteful processes and duplicate work. (This is much more difficult when expertise is “siloed”)

Automation also eliminates much of the human error that can occur when minor details get overlooked. This becomes more important as your systems continue to diversify.

By dealing with a single expert - and automating your backup process – your company can continue to ensure optimal data safety as its IT infrastructure grows in complexity. And this 2-step approach can also be applied to just about any functional area of IT.

About the Author: Patrick Jobin’s company has been offering online backup software for IBM iSeries, Linux, Mac and more.

Free Cloud Based PHR (Personal Health Record)

What happens in case of a medical emergency? You are out of station, far away from your near & dear ones, met with an accident, sort of emergency. What’s the best way to help your attending physician to take crucial decisions of drug related allergies or medical history?

Personal Health Records (PHR) may come to your rescue if you’ve maintained one.

Wikipedia defines PHR as:

“A health record that is initiated and maintained by an individual. An ideal PHR would provide a complete and accurate summary of the health and medical history of an individual by gathering data from many sources and making this information accessible online to anyone who has the necessary electronic credentials to view the information.”


Optional Info:

Though PHR may sound like an EHR(Electronic Health Records) there’s a marked difference between the two. A PHR is initiated by an individual whereas an EHR is initiated by the health care providers and may be legally mandatory in most of the countries.


Free Cloud Based PHR

  • Google Health
    • Available everywhere without any restriction.
    • Import medical records from hospitals & pharmacies.
    • Sign up & Access through Gmail Account.
    • It’s not only a storage, you can also produce intelligent reports/charts for analysis.

Important Update: Google Health is retiring January 1, 2012; data available for download through January 1, 2013. Read the official announcement at Google Blog.

  • Microsoft HealthVault
    • It’s a platform that can be integrated with many PHRs.
    • It can be used by health care providers (i.e. EHR)
    • There are many compatible devices (pedometers, blood pressure monitors, weight scales) that can be connected to HealthVault connection center to upload your device data directly to HealthVault record.
    • Currently launched only for two countries: US & UK
    • Sign up & Accessed through Windows Live Id.

Benefits of a Cloud Based PHR

  • Organize your health info in one place.
  • Gather your health/medical records from hospitals, doctors and pharmacies.
  • If you wish, Share your info securely with your doctor, health care provider or family member.
  • Analyse & gain insight from your health records.

PHRs can Include following Information:

  • Medications (doses & frequency).
  • Allergies
  • Drug interactions
  • Illnesses & Hospitalizations
  • Surgeries
  • Immunization
  • Test results
  • Insurance
  • Family history
  • Fitness records (weight, height etc)

Sign up for these Cloud Services?


Sharing personal medical information is a sensitive issue. Though a PHR empowers you as you are in complete control of your own profile (you decide what you want to share & what you want to keep private) sign up for these services after reading & understanding the Privacy Policies of the corresponding service provider:

HP + Bharti intend to Offer Cloud Services to SMBs

If the deal goes through, it’ll be a good news for the thousands of SMBs / SMEs in India, who are still waiting for their 1st affordable Cloud Application. At a later stage, a few more players may pitch in to make it a more meaningful deal. It may also prompt a few other partnerships by other cloud vendors for affordable solutions for SMBs/SMEs. I bet there’s a billion dollar opportunity & there’s indeed a gap to be filled when it comes to IT implementation in SMBs. In contrast to the sky rocketting prices of traditional model of software development, Subscription based Pay-Per-Use model of cloud apps (SaaS) is the main attraction when it comes to implementing applications for SMBs. If you are not so convinced about the existing opportunities, read here Cloud Computing: A Catalyst for IT adoption in SMEs/SMBs


As HP is a leader in IT infrastructure equipments, it can take care of the IaaS (Infrastructure as a Service) layer of the Cloud i.e. Data Center. The Indian telecom giant Bharti (It offers Telecom Services with Airtel brand name) will offer its optical fibre network and bandwidth to cloud data centers. Read press report here HP, Bharti in talks to offer cloud services for SMBs.

What we Expect from this Joint Cloud Initiative?

  • As both the player’s core strength doesn’t lie in the other two cloud stack i.e. PaaS and SaaS; it’ll be interesting to see which cloud platform (PaaS) support they are offering. There are various choices, but in my view the best option, which covers most of the development tools and programming languages is Microsoft’s Windows Azure Platform. It offers multiple development tools & languages to choose from; viz. .NET (C#, VB.Net, C++), Ruby, PHP, Python and Java. By default it supports Visaul Studio IDE, apart from that it also has plug-ins for Eclipse. Moreover, if you can have the development platform in-premise you can port your cloud app to your in-premise environment and vice-versa. Unlike in the past, it ‘seems’ Microsoft intends to make Windows Azure an Open Platform.  
  • Also, from a developers perspective, the offerings should be cheap or free till the service gets a significant number of users/customers. Pricing wise something like Google App Engine! In the long run, with a proper strategy these data centers may empower a developer or a group of developers to create their own cloud application at a ridiculously low price and offer them as a service. Power to innovate! for Cheap & Best service.
  • There are other PaaS as well which I am not so familiar with to offer my suggestions: Check here for Emerging PaaS.

What do you expect?
