When installing the Master instance of your JFrog Distribution service, the DISTRIBUTION_MOUNT_ROOT variable is set (this defaults to /home/USER/.jfrog/distribution). You need to keep backup snapshots of the Distribution and Distributor services Home folders: DISTRIBUTION_MOUNT_ROOT/distribution.
Exception for Versions > 2.x
Make sure to exclude distribution.local.config.yml and distributor.local.config.ymlfrom both folders.
