Is It Right to Compress Your Backup Data?

Advantages

Compression is actually a mathematical process which can take data and make it smaller via removing the redundancy and repeated patterns. In other words, it is able to reduce the file side by encoding the data in a much more effective way.

So, it is apparent that the most superior advantage of compressing your backup data is that it can make your backup data smaller, therebsy saving a lot of space on the backup storage device. Therefore, if your device tends to run out of space, it is a good option to compress the backup data.

Disadvantages

Nevertheless, compressing backup data can cause some troubles as well, like the followings.

  1. First off, compression is a kind of CPU-intensive activity. If your PC is too old and slow, it’s inadvisable to run compression during backup. Otherwise, your computer may be prone to get stuck and even crash.
  2. In addition, compression backups will take some time, which will make the duration of backup much longer. Similarly the course of restoring backup will take more time as well.
  3. If the entire backup is compressed, when a bad sector appears in the backup, it’ll be more difficult to recover the backup. That is to say, if a single bit goes wrong, all the left of compressed data will become compromised, too. In a nutshell, a single error can damage the whole backup in a moment.
