Many users may select to compress their backup data to save drive space. However, should you compress backups? This is a common question among users. Hence, in this passage, we will aim at this issue and expose its pros and cons in detail. First, we need to figure out what backup compression is.

What Is Backup Compression?

Compression is one of the most efficient ways when it comes to reduce the size of backup copies. During this compressing process, the file size is reduced by using special encoding. There are two types of compression: lossless compression and lossy compression.

Lossless compression allows users to shrink the size of data without losing the ability to recover the original data. On the other side, in lossy compression, users lose the original data in the process. Most users choose to have a lossless compress, but how does lossless compress work? 

How Does Backup Compression Work?

Backup compression is a process where the size of files is reduced by re-encoding the files to use fewer bits of storage than the original file. The fundamental element of backup compression is that the original files can be transferred or stored, recreated, and then used. Besides, compression is not infinite, and it is impossible for users to continue compressing the file further and reduce the size to nothing.

Well, what will happen to your backups if you compress your backups?
