Continuous data protection is a system for backing up computer files and data. The need for employing such a system is rooted in the bleak reality that loss of computer data costs companies many thousands of dollars a year. Computer crashes, natural disasters, vandalism and computer viruses can all cause an irreparable amount of data loss. A company or even an individual who works for themselves who does not take proper measures to backup their system are often financially and otherwise devastated by the results of such a disaster. It is important to understand how continuous data protection actually works, the benefits it offers over other forms of data backup and what you can expect in terms of cost.
Continuous data protection is a system for backing up computer data. It is otherwise referred to as real time back up or continuous backup. Traditional scheduled backups save data at predetermined intervals. If a situation of data loss presents itself in between the set backup schedule only the latest backup point will be available for restoring system data and any modifications made to your data subsequent to the last backup will vanish. Continuous data backup means that changes are made as they happen, hence the referral to real time. This ensures that no data is ever lost. Even though the first full backup of your data is time consuming, ensuing backups are quick because they just save data that is new. This method is beneficial in that it does not disrupt the efficiency of the system nor does it cause any slow downs in the productivity of employees who are working on the network being backed up.

The system of backing up computer data onto offsite or online locations has risen in popularity. The reason for this is that having a backup of your data that is kept in a separate location is the only way to stay protected from physical harm such as natural disasters. Think about the computers in your home office or business being completely wiped out in a hurricane or fire. If your backups were on site, they would be lost as well. Continuous data protection also has the added benefit over conventional backup types in that it saves you considerable sums of money since you do not need to buy any equipment to store or carry out your backups. People work out of their homes a great deal today and they do not have any technical support at their disposal. Data backup that is done online is one of the best ways of protecting these workers from the perils of losing data.

As already mentioned, continuous data protection can be much cheaper than traditional backup methods such as tape libraries and backup equipment. In addition, the fact that it only saves your data set once and subsequently saves only the changes means you are storing less data which will save you money. Decide between the available options capable of backing up your data using a method that is best for your company’s particular requirements. Do not choose a lower priced backup system over a superior backup system since you could be jeopardizing the data which represents the backbone of your business.
