Each build and release pipeline creates a directory under the agent working directory to store the source code, artifacts, and test results. Some builds consume more space than others; as projects evolve, some builds are used more than others. As you may have guessed, this results in agent maintenance activity to clear out the agent work directory. While you wouldn't want to remove everything from the directory, you would certainly be looking to remove some of the less-used build folders. Luckily, the agent comes with out-of-the-box support for pool maintenance. In this recipe, we'll learn how to configure the agent-pool maintenance schedule to automatically free up storage from the agent work directory by removing unused build folders.
To configure the agent pool maintenance, you need to be part of the build collection administrator group or in the administrator role for the specific agent pool.
