I am sure many of you have heard about the benefits and advantages of online backup services and protecting and storing your data offsite. But the ins and outs of such a system go way beyond just collecting, encrypting and transferring data. Advanced online backup services also provide online backup replication and continuous data protection. These services are mostly applicable to business users, who may have extremely important data storage needs, applications and costly software to protect. However, regardless of what is it that you need stored and protected, always search for a professional online backup service, in order to be sure of the safety and security of your files twenty-four hours a day.
Online backup replication is a process that has become more and more crucial to businesses world wide. The process basically copies data from one server to another in a cumulative manner. There are two types of replication, according to the method used, file level replication or volume level. The idea is that everything that changes or is being added at the source, it is also immediately replicated to the second host. There is also a difference to be made between synchronous and asynchronous replication. The first one recognizes the changes in from the primary host only after they have been replicated to the second one, or to the target. The asynchronous replication does exactly the opposite. First, it acknowledges the write and after that, duplicates it. Both of them have high and low points. For example, while the synchronous replication is constantly up to date, the amount of time required to actually perform the replication is higher, because the recognition of the write is delayed. The main advantage of the other type of online backup replication is that it does not affect the performance of the primary application in any way.
Continuous data protection is the process of copy saving of all data in a computer whenever changes are made. You can also come across the term of real-time backup or continuous backup, which are all the same thing. A great advantage of this process of continuous data protection is that the user or the administrator are able to fully restore the data storage, at any moment in time. All the changes registered to the data are stored separately, which enables you to see the evolution of data in time. The process can be implemented through several methods, depending on the needs of the end user, but it is undeniably a highly efficient method of data storage.
Now, the difference between online backup replication and continuous data protection consists in the fact that replication only secures the last version of the files, the most recent copy. The CDP, by storing all changes on to separate destinations, prevents a complete loss in the case of corrupted data storage. By using this process, you will be able to restore the last uncorrupted version of the data, which can prove to be extremely valuable. Anyway, whatever system you think suits your needs best and you feel comfortable with, make sure you employ the services of qualified and professional online backup providers that you can trust.
