IO Throttling

If you are experiencing high CPU load during your backups with tar you can throttle the IO to take load of your CPU

Example 5.19: Throttling XML example

<!-- source tar -->
<source type="tar">
  <option name="path" value="htdocs/uploads"/>
  <option name="throttle" value="5m"/>

With a configuration like in the example above you make sure that you only write 5 Megabytes each second. This way you backup may take longer, but your CPU is able to handle other stuff as well.

This is done via the CLI tool pv. To you this feature you must have pv installed on your server. If you are using phpbu on Windows, you can't use this feature.
