Backup and Disaster Recovery; Hyper-V Server Virtualization

Data loss can be quite discouraging, and it takes the organization quite behind in operations and all their undertakings. There is, therefore, every need to back up the data for easy recovery when it’s needed. A lot of platforms exists to facilitate this. Backups should, however, be done as regular as possibly to minimize the risk of any loss of information vital to the organization’s going concern. Insurance offers a lot of options for business to get back on their feet but for data, you need to take the step to safeguard your organization so as to enhance its performance.

Backup and disaster recovery for Hyper-V server’s virtualization

This is a piece of technology that is characterized by the regular backup of data on a virtual server, relocating the virtual server at the location of your choice based on your assessment of risk that may occur. As well as virtual machines that power your servers after a disaster. This is quite a revolutionary in the technology world and has played a vital role in the safeguarding of business information.

Hyper-V Server Virtualization

Backup site

This entails a place, could be virtual where all the processing can be diverted in the event of a disaster. Since all the software is linked, it will be much easier and faster to continue processing easily without bringing the activities of the firm to a standstill. You have the choice of always linking your information to the backup site or holding the information until the appropriate backup time reaches.

Virtual backup software

The software ensures quick access to data in the face of a disaster. The installed software is responsible for the fast recovery of data, as well as facilitating the organization, getting back to normal operations faster.

Alternate server and a virtual platform

This is an alternative, to the setup backup site. It has to have an adequate source to accommodate processing when the need arises. This, therefore, ensures that the backed up data is not lost in case the original backup site is down and there is a need to transfer processing to the backup site.

Replication software

This enables the returning of operations back after the disaster. It could be manually linked to other alternate platform or automatically linked, based on your needs and the price you are willing to pay as well.

Any loss of vital information may end up costing the organization a great deal of profit. Make the right choice today and choose the best data backup and recovery option. Consult your technician, alongside your technical team, so they help in installation of the data recovery system. It’s a decision that needs to be made fast, however, take the time to evaluate the alternatives, so you are sure you have the best. Check the reputation of the firm selling you the software as well to minimize the risk of any inconveniences in the future. Reading reviews will be quite helpful or getting a referral in making a choice as well.

How to Make Your Online Data Secure

Storing data online can be very efficient, but at the same time risky, but if you compare it with other forms of storage, you will find that it is much better. Online storage should be accompanied with backup solutions. The security of your online data can sometimes be compromised leading to the loss of important files and documents or leakage of crucial information. The following are some of the ways on how to make your online data secure.

1. Monitor your social media privacy settings

Social media is one of the places that the scammers can use to steal crucial information from you. If you reveal too much information in your privacy settings, they can easily use it to hack into your accounts and steal your online data. Therefore, ensure that you check your privacy settings every now and then to check if there is something that can give you away.

2. Never use the same password always

You may think that using a similar password for all your online accounts will make it easy for you to remember, but in essence, that is a loophole you are presenting to scammers. When creating passwords, use combination of numbers, upper case and lower case letters and characters to make it harder for scammers to guess your password.

3. Set up two email addresses

Having two email addresses can help protect a and secure your online data because you can never know what kind of people see them and use them to send spam emails with malicious links which can steal or destroy your online data if you click them, have two email addresses; one for family and friends and the other for promotional content so that you can be able to detect any online suspicious data secure4. Encryption

Encryption entails giving your data a key that only you can read and know alone. The cloud service company you choose for securing your data should allow you to choose your own key so that you can be sure that no one else is aware of it.

5. Data storage location and accessibility

This counts a lot in keeping your data secure. Some online data storage companies have branches around the world; you should not allow your data to be stored where you can easily get access to it. They should also be able to provide you with up-time statistics and whether there are any guarantees for safety.

6. Disaster preparedness

The facility where you store your online data should be prepared for any kind of disasters such as fire, floods or earthquakes that might arise at any time and pose a risk to the security of your data. The company should have strategies in place to deal with such emergencies in case they arise.


Keeping online data secure requires that you be alert at all times and if you notice something is not right, you should raise an alarm instantly.

Who is Carly Fiorina?

Carly Fiorina –A business leader in her quest for American Presidency


If you are amazed by the fact that a woman who began her career as a secretary could became the Chief Executive Officer of one of the world’s largest technology companies then surely you must be curious to know her name.  It is Carly Fiorina, the feisty republican politician who is currently a strong contender for the American Presidency in 2016. The lady with a mission is out to bring about a change in the way the country is ruled today by career politicians and seeks public support to become the true leader of citizens without any political ambitions only to serve and lead the country with the ability to answer questions without any political overtones. She is interested in the well being of the people of the country without any political interests and personal benefits.

In-built leadership

She had made best use of her leadership qualities  during her eventful career that saw her reach the pinnacle of business leadership that earned her the reputation of  The Most powerful Woman in American Business in 1999. She was chosen to become the Chief Executive Officer of the technology giant Hewlett- Packard (HP) in 1999 that made her the first woman to become the leader of Fortune 50 business. She also became the first outsider, in the 60 years history of the Company to be chosen for that position.

From start to the top

Born in 1954 in Austin, Texas, Carly Fiorina graduated from Stanford University and got her business degrees from the University of Maryland and Massachusetts Institute of Technology. Her father Joseph Sneed was a law teacher and judge and her mother Madeline was a painter. She started her career in AT & T in 1980 as a sales representative and moved ahead fast in her career during her tenure of 9 years in this company. Here she met Frank her husband whom she married in 1985. She quickly rose to the senior leadership position and moved ahead in her career to lead several big companies in Seattle and Silicon Valley that culminated in her being chosen as the Chairwoman, CEO and President of HP.


If awards are any indication of success then she has earned plenty of them in her career. From being conferred honorary fellowship of the London Business School to finding a place among Top 25 Executives, not to talk about being The Most Powerful Woman in American Business and more, her leadership qualities have earned her just too many accolades. That HP rose to become the eleventh largest company of America speaks volumes about her leadership prowess.

The turning point

After leaving HP, she decided that it was time to give back. She led a number of non-profit organizations and charities and got associated with governments at state and national level in the advisory capacity.  As devout Christian, she heads an organization that helps people to conquer poverty.

Banking on her strength of being driven by principles over politics, she now aims to lead the country as its President in 2016 and is a contender for the post as a Republican candidate.


Who is Ben Carson?

Ben Carson –The man with a new prescription for America


A man who wears many hats is perhaps the best way to describe Ben Carson. A trained neurosurgeon, who is also identified as a journalist, author, philanthropist and politician, has now set his eyes at the hot seat of the country’s President.  Politics did not come to him naturally, but his views criticizing President Obama’s policies on fiscal and social issues drew the attention of the media who labeled him a Conservative. Thus a reluctant politician that he calls himself was born in 2013 at the National Prayer Breakfast when he aired his views in the presence of Barack Obama.

Doctor in the making

September 18, 1951 is the date of birth of Benjamin Solomon Carson, one of the two sons of Robert Carson and Sonya, who was born in Detroit, Michigan. The children were brought up by their single mother as their father had opted to desert them in preference to another family that he secretly reared. They grew up in extreme poverty with their mother working as a domestic help to support them.

Under the strict guidance of their mother, who despite being a school dropout had excellent knowledge about the fundamentals of life, was able to inculcate positive vibes in her children. This made Ben daring enough to dream about being a doctor some day. He became an avid reader who loved to spend time among books of different kinds that allowed him to play on his imaginations.

His habit of reading impacted his studies positively and he turned out to be a class topper in the 6th grade with an insatiable appetite for knowledge.  By the time he completed school, he was clear in his mind to pursue a medical career.  He joined college to fulfill his dream and besides the scholarships that he earned he had to work to pay for his studies.

The career begins

After graduating from Yale in psychology in 1973, he joined the School of Medicine at the University of Michigan to become a neurosurgeon. He married Candy Rustin in 1975 and the couple moved to Baltimore, Maryland in 1977 as Ben became a resident surgeon at John Hopkins University. In only 5 years, he rose to the position of chief resident in neurosurgery at the same place.

Since then, there was no looking back. In 1985, Ben became director pediatric neurosurgery and in 1987 he attracted international attention by conducting a rare surgery that successfully separated 7 month old twin boys who were joined at the back of the head. He conducted another successful surgery to separate conjoined twins in Zambia in 1997. In 2001, he was named among 20 foremost scientist and physician by Time magazine and CNN.

Political views

His traditional political views are blended with common sense and based on conservative philosophy that has the backing of Republicans who have always denounced the approach or ‘political correctness.’ He endorses government sponsored health savings account that would allow people to save money.

With a vision to do what is right without any political under pinning, he now seeks Republican presidential nomination for 2016.

Who was Steve Jobs?

The wonder named Steve Jobs


Steve Jobs was known to the world as the co-founder of Apple Inc, the computer company that took the world by storm. Steve Jobs had the fire in him and was capable of capturing the world’s imagination in the presenting the most advanced and user friendly computers that not only met people’s expectations but surpassed it.  His enormous talent as a technical entrepreneur coupled with tremendous business acumen earned him fame and fortune that turned him into a legend during his life time.

Early years

Born on 24th February 1955 in California to an unwed couple named Abdulfattah Jandali and Joanne Schieble, Steve Jobs was adopted and brought up by Paul Jobs and his wife Clara who were working class couple in California.  Steve grew up with them in Mountain View and after completing high school enrolled in Reed College only to drop out after the first semester in 1972.  Steve was only interested to pursue courses that attracted him.

The beginning

His long time friend Stephen Wozniak was exceptionally talented and had uncanny interest in electronics. He embarked on a mission of building computers sometime around 1975. Steve, who had been separated from Wozniak for a few years, realized the immense potential of his talented friend with whom he had reunited with in 1976 and convinced him to start a computer company as Wozniak had successfully built his own computer board at that time. The visionary within Steve Jobs struck gold with his farsightedness as Apple Computer was born on all fool’s day, 1st April,1976.

 Computer boom

Apple I computers were manufactured in a garage in Steve Job’s home and was sold in the market to computer dealers. Meanwhile, Wozniak was busy building a much better computer that supported color graphics, was much powerful and had expandable memory. Realizing the immense potential of Apple II, as it was named, Steve lost no time in arranging for funds and got busy in seeking venture capital for the project. With investment of $250,000 from Mike Markkula the company got the buoyancy that it needed. In no time the company wrote a fairy tale success story as the market witnessed unprecedented computer boom and its owners became multi millionaires, conquering every peak of business challenge.

Break and back

The journey of Steve Jobs was not smooth always but still he emerged a winner. In 1985 Steve was thrown out of Apple and the next 10 years saw him forming new enterprises that dealt in computer graphics and animation. In a magical twist of events, Steve Jobs found his place back in Apple in 1995 when his new found company was acquired by Apple. The magic of Steve Jobs showed up again as he could turn the fortunes of Apple once again with a series of new launches that included iMac, iPad and iPhone as well as iPod that changed the world of  communications and music and entertainment for ever.

Steve Jobs died on 5th October 2011 after a prolonged battle with pancreatic cancer but his legacy still continues.



Who is Michael Dell?

The genius of Michael Dell


Michael Dell is the longest serving CEO of the computer industry having headed the founding company Dell Computer Corporation ever since its inception in 1987.  He is one of the most successful American businessmen like Steve jobs of Apple and Rod Canion of Compaq who came into prominence riding the computer boom of the late eighties and early nineties. But what makes him unique is his ability to stay with the company that he had formed quite unlike his compatriots who had been separated from their founding companies.  This maverick entrepreneur is also a philanthropist and an author.

Formative years

Computers have attracted Michael ever since his childhood and he was hooked to his Apple IIe much to the dislike of his parents who preferred to see him become a doctor. He wanted to please his parents and after completing high school in 1983 did not mind enroll himself at the University of Texas. Surprisingly, while staying at the university dorm, he spent his leisure hours by upgrading outdated second hand PCs that he procured from the retailers and sold the refurbished machines from his room. His efforts met with great success and signaled that it was time for him to take a plunge into real time business beyond the campus walls.

Fortune’s call

The time was right for him as he had correctly perceived.  His business efforts in selling reconditioned and upgraded PCs during the summer break fetched him $180,000 and despite furious opposition from his parents who wanted him to continue with his education and whom he had promised to go back to school if his business efforts failed, he never went back to the campus again.

The business model

Computers at that time were yet to dominate our lives. But Michael Dell, the visionary that he is, was quick to perceive that very soon computers would become a commodity- something that people would just not be able to keep away from. He understood the need to position computers in the same was as commodities and focused on price and delivery that matter most for transactions in commodities. He modeled his business based on his strength of assembling computers on his own by sourcing spares from the market and decided to reach out to the buyers directly for selling the products by using telephonic communications. This would enable him to offer lower prices by at least 15 percent as compared to any established brand. Thus the model of direct selling was born that changed the face of marketing for ever.

Path breaking approach

The direct selling model paid off and the master stroke from Michael Dell came when he decided to sell only customized computers instead of offering some standard variety in the market. He started making machines exclusively for customers needs and it was completely tailor made. This strategy worked wonders and the company sales soared phenomenally.

Despite going through an interim lean patch, the conviction and trust of Michael Dell in direct selling has made him the emperor of a computer empire with an estimated net worth of $19.5 Million for himself in 2015.



Data Recovery from databases

Data recovery is the process of restoring data that has been lost, accidentally deleted, corrupted or made inaccessible for any reason. In enterprise information technology (IT), data recovery typically refers to the restoration of data to a desktop, laptop, server, or external storage system from a backup.

A recovery-only file restore can be useful in the following situation:

A database is restored piecemeal. After restore of the primary file group is complete, one or more of the unrestored files are consistent with the new database state, perhaps because it has been read-only for some time. These files only have to be recovered; data copying is unnecessary.

A recovery-only restore operation brings the data in the offline file group online; no data-copy, redo, or undo phase occurs. The ability to restore databases from valid backups is a vital part of ensuring business continuity. Backup integrity and restorations are an important piece of the IT Governance Institute’s IT Control Objectives for Sarbanes-Oxley, 2nd Edition. In many instances, IT auditors merely confirm whether backups are being performed either to disk or to tape, without considering the integrity or viability of the backup media.

One of the key responsibilities of a database administrator (DBA) is to prepare for the possibility of media, hardware and software failure as well as to recover databases during a disaster. Should any of these failures occur, the major objective is to ensure that the database is available to users within an acceptable time period, while ensuring that there is no loss of data. DBAs should evaluate their preparedness to respond effectively to such situations by answering the following questions:

  • How confident is the DBA that the data on which the company business depends are backed up successfully and that the data can be recovered from these backups within the permissible time limits, per a service level agreement (SLA) or recovery time objective, as specified in the organization’s disaster recovery plan?


  • Has the DBA taken measures to draft and test the procedures to protect as well as recover the databases from numerous types of failures?

The following is a checklist for database backup and recovery procedures

  • Develop a comprehensive backup plan.
  • Perform effective backup management.
  • Perform periodic databases restore testing.
  • Have backup and recovery SLAs drafted and communicated to all stakeholders.
  • Have the disaster recovery plan (DRP) database portion drafted and documented.
  • Keep your knowledge and know-how on database and OS backup and recovery tools up to date.

A data recovery company in Houtston Texas has developed some advanced sql recovery techniques for the seriously damaged cases, they can be found at  Also, a well recommendable commercial sql data recovery software can be found at SQL Database Recovery Software

Either way I would recommend creating a backup copy before sending out the database to a specialized data recovery lab or even before attempting a do it yourself recovery (DIY) with some of the recomended software products. One of the main problems is that commercial sql recovery software will attempt to find corruptions within pages and if the application can not repair the page within the record, it will simply delete the page and record entry. This can sometimes leave the database in a state that is functional, but neverthelsess the relations of the database tables can produce undesired results when your front ent application attempts to query certain database records.



Computer forensics really do solve crimes


Computer forensics integrates the fields of computer science and law to investigate crime. For digital evidence to be legally admissible in court, investigators must follow proper legal procedures when recovering and analyzing data from computer systems. Unfortunately, laws written before the era of computer forensics are often outdated and cannot adequately assess the techniques used in a computer system search. The inability of the law to keep pace with technological advancements may ultimately limit the use of computer forensics evidence in court.

Privacy advocates are growing especially concerned that computer searches may be a breach of a suspect’s human rights. Furthermore, as methods for encryption and anonymity grow more advanced, technology may be abused by helping criminals hide their actions. Ultimately, the role of technology in computer forensics may not reach its full potential due to legal boundaries and potential malicious intentions.

Forensic science is the scientific method of gathering and examining information about the past which is then used in a court of law. The word forensic comes from the Latin forēnsis, meaning “of or before the forum.” In Roman times, a criminal charge meant presenting the case before a group of public individuals in the forum. Both the person accused of the crime and the accuser would give speeches based on their sides of the story. The case would be decided in favor of the individual with the best argument and delivery. This origin is the source of the two modern usages of the word forensic – as a form of legal evidence and as a category of public presentation. In modern use, the term forensics in the place of forensic science can be considered correct, as the term forensic is effectively a synonym for legal or related to courts.


Forensic investigations seek to uncover, analyze and preserve evidence to be used in criminal proceedings. As technology has become increasingly prevalent in everyday life, investigations have spread to computers, telephones and other electronics.

Computer forensics has been indispensable in the conviction of many well-known criminals, including terrorists, sexual predators, and murderers. Terrorist organizations may use the Internet to recruit members, and sexual predators may use social networking sites to stalk potential victims. However, most criminals fail to cover their tracks when using technology to implement their crimes. They fail to realize that computer files and data remain on their hard drive even when deleted, allowing investigators to track their criminal activity. Even if criminals delete their incriminating files, the data remains in a binary format due to “data remanence” or the residual representation of data. File deletion merely renames the file and hides it from the user; the original file can still be recovered.

Microsoft SQL Server vs. Oracle Database

Any business that needs a lot of data and information for their daily business activities must consider the high availability capabilities for the database. Data is a sensitive and highly critical asset of any organization and it needs to be handled with proper care. There are several databases including MySQL, Sybase and Microsoft access. But for several years we have had a constant battle between fans of the Microsoft SQL Server and those of the Oracle Server. Of course most fans argue from the point of perception of functionality but that is not the only thing you ought to consider before making a choice. But let’s now crack out the nut and see which one is better in what aspects. Let us look at a closer analysis of the Microsoft SQL Server vs. Oracle Database:

  1. Language

One of the most fundamental differences between the Microsoft SQL Server and the Oracle Database relational database management systems is the language that they use.

Even though both of them have the Structured Query Language or SQL, Microsoft uses the T-SQL or Transact SQL; which is an extension of the SQL that was originally developed by Sybase before being used by Microsoft. On the other hand, Oracle uses the Procedural Language/SQL or PL/SQL. In other words, both sets of servers use different dialects or flavors of the SQL but the languages have different capabilities and syntax.

The main difference between both sets of languages, however, is the manner in which they handle stored procedures, variables and the in-built functions. The Oracle PL/SQL easily groups procedures into different packages—something that the MS SQL Server cannot handle.

  1. Organization of Objects of the Database

The MS SQL Server performs the important function of organizing all objects including procedures, views and tables by the names of the database. The users are then assigned a login which is granted direct access to a very specific database along with its objects. Each database also contains an unshared, private disk file on the server.

On the other hand, the Oracle Database has all the database objects grouped according to schemas that are actually a subset of a collection of database objects. All the database objects are normally shared among all the users and schemas. However, the sharing capability is limited to some specific tables and schemas through the requirement of certain permissions and roles.

  1. Transaction Control

One of the biggest differences between the Oracle Database and the MS SQL Server is the power of transaction control. For your understanding of this aspect, a transaction will be defined as a group of tasks or operations that ought to be treated as a single unit. In other words, a collection of various SQL queries modify records so that all are able to get updated at the same time. For instance, if there is a failure of updating one of the records then all the records should not get updated at all.

The MS SQL, by default, executes and commits each task or command individually. Therefore, it is impossible or difficult to roll back the changes if any error is encountered in the process. These are commands in the MS SQL:

  • The “Begin Transaction” command is used to indicate the commencement of a transaction
  • The “Commit” command is used to end a transaction and write changed data or information to a disk
  • The “Rollback” command allows for protection against incidences of data corruption when used properly in the aspect of error handling. This command also discards any changes that may have been made is a particular transaction block. The user cannot roll back any other information apart from what the “Commit” command can do.

On the other hand, every new database is handled as a new transaction in the Oracle Server. When commands and queries are issued, the changes are only effected in the memory and nothing else is committed until a “commit” statement is issued. Once the “commit” command has been executed, the next command is only used to commence the process once again. Therefore, this gives the handler greater flexibility that assists in controlling errors as well.

  1. Operating System

While the MS SQL Server is executed on the Windows operating system, the Oracle Database can be executed on several operating systems including Windows, Linux, z/OS, UNIX and Mac OS X.

  1. Features

Both the MS SQL and the Oracle Servers have similar principal features including referential integrity, Unicode, transactions and ACID.

  1. Architecture

Both servers use the same architecture which offers numerous advantages to the user: the relational model.

  1. Access Control

Both servers share various aspects of access control including audit procedures, security certifications, native network encryption, resource limit controls, password complexity rules, brute-force protection and enterprise directory compatibility. However, the MS SQL Server has additional access controls including separation of duties, running unprivileged and patch access that make it function much better.

  1. Database Capabilities

Both servers share numerous database capabilities including the except function, blobs and clobs, the union function, windowing functions, outer joins, merge joins, intersects, inner selects and inner joins. These improve the performance of both servers.

  1. Indexes

Both the MS SQL Server and the Oracle Database indexes include spatial, partial, full-text and expression components. However, the Oracle Database has additional indexes including the hash, reverse and R-/R+ Tree that makes its performance better in this area. sql-oracle

  1. Support Options

Users of the MS SQL Server can seek assistance through a Blog and various Forums while Oracle Database users can only seek assistance through various forums.

  1. Cost

The MS SQL Server has always been cheaper as compared to the Oracle Server. Therefore, this is a better option in case you are factoring in your financial budget.


From the discussion above, it is very clear whether there is a particular kind of server you can lean. Both servers are good. However, the best option depends on your business database requirements. You can seek advice from our database experts before making an informed decision today.
