What is the additional deposit?

Incremental backup is a type of strategy often selected by information technology administrators, home business owners and personal computers to maintain the existence and integrity of data. If only changes that have been backed up in user data or files that make up the system are called an additional backup. Changes are "additions". It is a form of continuous data protection, so the system can be restored in case of system failure and accidental data deletion. The system recovery is made possible using the media on which copies of the necessary data have been stored by implementing the additional backup strategy. For example, when someone writes and saves a letter using text processing software, what is generally called user data or user files. Changes can also be made in files that consist of thsamous operating system and files of the software programs that run under it. Although it can choose an additional backup strategy someone who is answeredIt is almost always combined with a full -time system of full backup of the system.

Central-based managers usually decide to make a daily additional backup to maintain the data that has changed or that has been created, along with the weekly backup of the whole system. There are different versions of this type of strategy and each version has advantages and disadvantages. One version includes each addition to back up the link to the original full system so that the recovery of the system requires only media holding the entire system and the last additional backup. If the data is backed up for tapes, it would only work with two system failure. The disadvantage of this version of the additional backup is generally seen in strongly used systems in which there are many files that could be very large.

Another version of this type of backup strategy includes previous additionsincrements instead of a complete system. Although this strategy requires less time, because there are fewer data on each tape or type of backup medium, it is not without disadvantages. Complete system recovery would require working with more than two sets of data. The data loss would require the launch of each set of user files, system files and all changes.
