  +If you would like to sync files from a local environment to a remote environment, you need to pass additional parameters:
  ```
  drush rsync @self:%files @lagoon.master:%files -- --omit-dir-times --no-perms --no-group --no-owner --chmod=ugo=rwX
  ```
  +This is also applies to syncing a remote environment to another remote environment, if you're not using the Lagoon Tasks UI to copy files between environments.
  +For example, if you wanted to sync the files from `@lagoon.master` to `@lagoon.dev` and ran `drush rsync @lagoon.master @lagoon.dev` locally, you will probably run into a "Cannot specify two remote aliases" error.
  +To resolve this, you would first need to ssh into your destination environment `drush @lagoon.dev ssh`, then execute the rsync command with parameters similar to the above: `drush rsync @lagoon.master:%files @self:%files -- --omit-dir-times --no-perms --no-group --no-owner --chmod=ugo=rwX`.
  +
  This is not necessary if you rsync from a remote to a local environment.
  Also we're [working with the Drush Maintainers](https://github.com/drush-ops/drush/issues/3491) to find a way to inject this fully automatically.
