If a network has 300 images of Windows 10, for instance, that consumes 4.48 terabytes of storage.

In addition to doubles of individual files, a network may also depend on duplicate disk images stored on virtual machines.

With data deduplication, once you have ensured that all video and music software is referencing files on your computer, you can delete any duplicates, freeing up space. The video file is copied, and it is this new file the program works with. A similar thing may happen with some video-creation software. This allows the music program to reduce memory consumption and get the most out of the speed of its hard drive because it essentially creates its own, exclusive, readily available dependency. With some music-creation software, such as older versions of Cakewalk, when you apply an effect to a clip of music, the clip itself gets copied.

Music and video creation software duplicating data: Music and video files are some of the largest files you may have on your computer.

Your computer examines what was there during the last backup, compares it to what it is going to back up, and then only backs up the new or different files. For example, each time you do a backup to your PC or Mac, the size of the backup varies based on the changes and additions you have made to your system. Some systems have deduplication already in place to prevent this. When you restore from a backup, what you get is a copy of the data you are looking for.

When the backup process has finished, you end up with two identical sets of data. Data gets duplicated during backups: Often, when an application creates a backup, it duplicates the data it is backing up.In many cases, you do not need another copy of the data being duplicated, and deduplication can get rid of these kinds of excess files. Apple’s iTunes can, for instance, be set to make a copy of every song you play, which results in duplicates on your computer. However, some apps are set to make a copy of the item on which they are dependent. When you play a song, the application may reach into that area of your computer and play the song from there. In this case, one of the prime dependencies is the storehouse of songs on your computer, tablet, phone, or another device. For instance, a music application will need to reference the music on your device in order to play it. Every application has dependencies that it uses, or “depends on,” to function. An application making a copy of a file it uses: This is so the file is more readily available within the application's dependencies.

There are a few reasons why this may happen: The need for data deduplication arises when data gets copied in your system. Data deduplication is the removal of duplicate data in a way that maintains the integrity of the system, as well as the functioning of applications dependent on the data being cleaned.
