It has been said that more than half of internet users have encountered data loss in the past. Online backup is a type of service that addresses this problem. Specifically, there is an online system that is designed to store or backup computer files for the users' convenience. Those who avail of this service would also have a software that would collect, compress and transfer the data to the servers of remote backup service providers. There is usually a schedule being followed when the computer files are to be collected, the most common being once a day.
The frequency of the data being collected depends on the target market of the specific service provider. There are LAN-based service providers for online storage solutions that can offer as much as real-time data collecting. This means that the computer files being stored are updated almost as often as the original files are. For establishments and companies that are very much dependent on computer files, these backup systems are indeed very assuring. This kind of service would be handy for disaster recovery. It would also be useful for restoring files that are accidentally deleted or corrupted for whatever reason.
There are varied types of data storage devices and the degree of security and portability vary. In the case of online backup service systems, software that has been altered to suit a client's needs is installed. The software basically is for computer files to be selected, extracted and manipulated before being sent to the storage server. There are many components that have been developed to make the transmission procedure and accessibility more dependable and versatile. For instance, there are compression techniques, encryption techniques that and de-duplication techniques to guarantee that stored data would be safe and is able to utilize the capacity and features of the provider.
These online backup systems do not require user intervention meaning there is no need for changing tapes, labeling and other bothersome procedures to make sure that the computer files would be updated or organized. Since the data is stored elsewhere and not the same location where the original data is saved makes it more effective. The remote backup services that are continuous would back up files as they are changing.

Since broadband internet access became more accessible to the public, online backup providers gained more clients. However, the internet speed of households still cannot be keep up with the speed capacity of storage devices. This poses a problem for those who need to store or modify large amounts of data. There are also privacy issues to be worried about especially when the files being stored also contain personal and sensitive data. A client would be charged for the online backup services according to certain factors. It could be dependent on how much data is being backed up, the number of versions of the files that are being maintained and the archiving options for the computer files stored. Because online backup service providers do not guarantee that the computer files stored can be kept private, most of them recommend that the files should be encrypted before they are to be transferred.
