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.

Encryption is an increasingly important set of technologies that enable customers to protect the personal data on computers, through public or private network, or in other machine-readable form.

For small and medium markets, the ideal approach to data encryption will be both affordable and easily integrated into a comprehensive data backup and business continuity systems solutions. This will include a powerful, standards-based encryption, and offers a powerful key management functions.

Imagine a bank with 20,000 customers, most with multiple accounts and bank cards. Every night, the bank makes a complete tape backup of the server core information.

Each of these practices can cause the tape to be mislaid or stolen from the loading dock, accidentally dropped off at the wrong location, or a lost or stolen from delivery van, among others. Once the tapes are in the wrong hands unencrypted data easily compromised.

Fortunately, the encryption function can be easily integrated into the organization’s backup process, protect all data on corporate servers and backup devices, and all the data taken from the site for archiving.

Keys and key management

A key is a piece of information, or parameters, which controls the operation of a cryptographic algorithm. Modern encryption algorithms typically use either symmetric keys or asymmetric.

Symmetric key method uses the same key for encryption and decryption. Symmetric keys are excellent for use with devices and equipment that need to share key is very limited. This usually happens with the backup data set, which one does not need to specifically allow access to many key parties.

If you lose your house keys, locksmith can choose a mechanical lock and help you regain access. If you lock your keys in the car, there are special tools that can help you open the door. But any method of encryption that allows this kind of “alternative access” in the event of lost keys will be fatal safe. These days, most of the encrypted data unreadable to thieves and basically totally lost to the owner in the absence of the necessary keys for decryption.

Implementation method

Data encryption can be incorporated into your workflow in a variety of different ways, each with advantages and disadvantages. When implementing data encryption on the network, there are four basic ways to approach the process:
