Title:  How to enable backup compression?


Compression is usually performed to decrease your disk space usage, but also has an inverse impact on your backup speed due to the increased CPU usage.

CA ARCserve D2D is capable of compressing files during the backup with different methods.

The available options are:

  1. None - No compression will be performed. Files will be pure VHD. This option has the lowest CPU usage (fastest speed), but also has the highest disk space usage for your backup image.
  2. Standard - Some compression will be performed. This option provides a good balance between of CPU usage and disk space usage. This is the default setting.
  3. Max - Maximum compression will be performed. This option provides the highest CPU usage (lowest speed), but also has the lowest disk space usage for your backup image.

Note: If your backup image contains uncompressible data (such as JPG images, ZIP files, and so on), additional storage space may need to be allocated to handle such data. As a result, if you select any compression option and have uncompressible data in your backup, it may actually result in an increase in your disk space usage.


Enable backup compression with the following steps:

  1. Open ARCserve D2D windows by
