Distributed version control allows files to be passed between nodes in a network, providing easier access and faster speed. However, without a main holding area, it may be difficult to ensure the latest version of a file is being used.
Distributed version control is a method of controlling computer files used for backups; features a distributed chain where each file can be passed to each node in a network. This is different from a normal or centralized backup, because the centralized version only places files in a central area. An advantage of this is that it is easier to access files over the network if the backup is sent to a node. One problem with using distributed version control is that it may be difficult to get the most recent backup.
A normal version control method is known as a centralized method, as there is a central holding area. Each node of a network sends files and information simultaneously to the central area. In this method, the nodes will not contain any backup information, because everything will be contained in the central holding area. While this system is simple and easy to use, it has speed and blending disadvantages.
Deployed version control is different. Although most networks may have a main holding area and all backup files are sent to this area, nodes can send files to each other. For example, if a user wants to send a file to another person during backup, it is possible. All nodes will normally send important files to each other to ensure that everyone has a local copy of the file. Even if a node does not have a file, it can still access the file from the main area.
Speed and ease of access are advantages when using distributed version control. One reason the speed is better is because most nodes have the files they need, so they can be accessed from your hard drive and not from a distant server. While the user must log in to the main area, it tends to be faster than the centralized approach.
Unlike the centralized approach, distributed version control doesn’t need to have a main area. If there is no root area, all nodes can still send files to each other, but a problem may arise. Besides asking other users, it will be hard to know if the files on your computer are the latest version. This means that it is normally best to use a main area so that all the latest files can be stored and accessed if needed.
