Bamboo build-dir excessive space can it be cleaned up with a cron job?
<p>We use Bamboo CI. There are multiple bamboo local agents and parallel builds across many plans. The build-dir in bamboo-home is many hundreds of gigabytes, and analysis shows that it just continually grows as new feature branches are added. Plans seem to be duplicated in each local agent directory, and also directly in build-dir.</p>

<p>Unlike expiring artifacts, Bamboo does not seem to clean this up by itself. For example, if a local agent is removed then the local agents build directory sits there forever taking up a significant amount of space.</p>

<p>Plans can be set to clean up at the end of a build, however this impacts problem analysis in the event of needing to do a post-mortem on the build.</p>

<p>Due to the directory running out of space I have just added a daily cron task to periodically remove files and directories that haven't been accessed for more than 21 days. When I first ran this manually I reclaimed 300GB from a 600GB partition. I want to know if others have encountered this same issue, and if it is safe to externally clean the build-dir in the long term. Could it impact bamboo builds?  Is there some bamboo option that I have missed that would do this for me?</p>

<p>Searching on the Atlassian site has not been helpful and yields no answers... what are others doing to tame this space hog?</p>
