thousands of computer users, from private individuals to small and large businesses lose important data due to The importance of backing up your data regularly can not be underestimated. Every year hard drive failures, natural disasters or other events.

Still many computer users do not back their data, either because they do not think data loss will happen to them or they do not know how to go about it. Here are some of the questions most frequently asked questions about data backup.

Your question: Answered

How likely is that I will lose my data?

The computer is a mechanical device and thus eventually will be damaged and stop working, potentially take your data with them.
How often should I back up my files?

Backup options are available?

You can back up your files using external storage media like flash drives, external hard drives, CD disks or DVD-RW, or even a computer tape if you have large amounts of data to store.

How do I choose the best solution?

Not really any solution that’s best for everyone. The best solution for you is one that makes sense from a cost perspective, it is easy to use and provides a level of protection you need.

You need to consider the importance of your data when selecting a backup choice.
How fast do you need to recover your data if it is lost? Local storage media tend to offer the fastest way to retrieve your data. These are all questions that you should consider when choosing a backup option.

Where the backup method is the most cost effective?

Over the long term, local storage media tend to be cheaper than the cloud backup. This is because you only have to buy all your storage media, while online backup services charge a monthly fee that can be added from time to time.
How do I know if my data secure?

Online data services using sophisticated encryption program to ensure that your data can not be hacked or accessed by the backup service employees. Encryption includes both the transmission of data to backup and storage service.

If you choose an external storage media you own, you will need to provide your own methods of security to ensure that the device does not get stolen or lost.

Do I need to back up all my files?

These days the safety and security of our data becomes increasingly important. Identity theft is a very real problem. Keeping our personal information is an important step to protect our privacy and ensure that our sensitive data can only be accessed by authorized individuals.

Encryption is a process used with increasing frequency these days and chances are that you send or receive encrypted files frequently, even if you do not realize it. Many email messages are sent in encrypted form as well as financial transactions and some file sharing program.

How Data Encryption Works:

Data encryption is achieved by a process that replaces your information with a code that can only be described if you have the encryption key. The use of the code to hide the meaning of the message has existed since the time of Julius Caesar.

Back in the days of the alphabet keys are used, for example, a letter will be replaced with another. We all have seen the kinds of puzzles in newspapers or magazines.
If you send an email using the encryption process, encryption keys can be included in your email client or as a stand-alone program.

Three Types of Data Encryption

1. Symmetrical Data Encryption

Symmetric encryption of data using file transmission through the programs you use. You must send a decoding key to the receiver separately from your message.

The biggest problem with symmetric encryption is that it’s possible for a hacker to intercept the key to decoding and file during transmission, and thus can read the message.

2. Asymmetric Data Encryption

Asymmetric key encryption involves two separate data decoding, the public key and a private key. This type of data encryption takes longer to transmit, but much safer. When you send a file, you encrypt files using your recipient’s public key. When the recipient receives the file, decodes them using their private key.

3. Data Encryption Software

Data encryption software is a computer program that encrypts a data file or packet of information sent through computer networks. The software uses encryption keys to prevent others from viewing sensitive data.

There are a number of companies that offer data encryption software for personal users. They use one or more of a number of different encryption algorithms to make your data is almost impossible to access without the encryption key.

Back up your important files and information is an integral part of good data management system and is the best defense against data loss due to hard drive failure or other system malfunctions. In this article we will see the importance of backing up your files, various types of backups you can perform and the type of storage media available.

Data Backup

There are two main reasons to backup your files. The first is for protection in the event of data loss. Over time, mechanical devices have a tendency to fail, and computers and hard drives are no exception. Unfortunately, in many cases come without warning. Back up your files regularly to minimize the effects of any hard drive or system failure.

The second reason is to save multiple versions of files that change regularly so that you can go back and retrieve information from a specific time period. Many business applications, for example, requires you to return to the previous transaction record and retrieve data from that date. Having a system of well-organized data storage allows you to perform this task quickly and easily.

Data Repository

When you back up your files, you’ll need to organize in some way to make it easier to retrieve data. There are several different models of data storage that you can use:

Delta vice versa: A reverse delta system to save the changes between the version of the current system and previous versions.

Full System Backup: A full system backup allows your computer will be restored exactly as it was before loss of data. This includes the operating system and all other application software and data.

Storage Media

There are several different media in which you can store your data. They each have their strengths and weaknesses. You should choose the method that best suits your circumstances and preferences.

External Hard Drives. This is an actual hard drive that you can attach to your computer and transfer the files you need to go back.
USB Flash Drives. Flash drives or data sticks are a form of external hard drive that can store data from your computer. They are usually less than four inches long and weighs one ounce or less and extremely portable.
Online Data Storage. Online data storage has become much more popular recently.
CD or DVD-RW disc. One method is the simplest and most expensive backing up data files to store them on disk CD or DVD-RW. While this simple and convenient, the disk can only store a limited amount of data. This may be suitable for storing data such as personal photos or files, but not practical for backing up large amounts of data.

Each person with responsibility for IT to know that high availability software is an important aspect of their work, but for those who are new to the world of IT, they may have some questions.

• Frequently Asked Questions: High Availability Software

An IT professional needs to know more about high availability software than just benefiting from it.

• What exactly is HA?

HA is the concept that every person in the IT world have heard, but what is it exactly? It is a combination of strategies and technologies necessary to implement in order to increase the availability of hardware, operating systems, applications and networks.

• How HA seen in relation to disaster recovery?

HA is a concept that aims through the disruption of production processes in a data center.

• Is the HA software is difficult to maintain?

It is recommended that you frequently test your HA environment to ensure that it is working correctly.

• What can protect HA software?

It depends on your needs and your budget. Often, budget constraints may limit you to how much data or data that you protect. That being said, you can use HA software to protect specific applications or entire server.

• Can I get rid of tape backups?

Since the backup tape serves the function of archiving, it is not recommended that you remove it. However, with high availability software, you need not rely only on tape backup in the event of a disaster.
