Traditionally, with our zero-downtime (atomic) deployment features, DeployHQ keeps 3 releases on your server, including the latest that is symlinked to from current. Any additional releases are then removed on a rolling basis during each deployment.
A number of users have requested the ability to set a number of releases to keep on their server, which we're happy to say has now been added as an option to the platform.
Just head to your server settings, and you'll find an Atomic Retention option within the normal atomic settings section. It will be set to 3, but it can be changed to any number.
Once this has been updated, all future deployments will use the setting. Just keep in mind that each release will take up additional disk space on your servers, so it's recommended to keep the number as low as possible.
