The only time you use the Server name field is when you have a web farm setup and specifically want the task to execute on 1 of the web farm servers vs. any of them. The task data field should be empty. I believe the task is set to run every minute or 5 minutes which is really plenty. It should be set to something like once or twice per day. No issues, have several clients using this feature for their content (it will not sync objects as they are not content).
