There is no universal answer. The main considerations are disk space and time scale on which pertinent events occur. grompp will warn you if you are producing a large amount of data, which makes the disk space problem easy to assess. As for the time scale of events, you will have to think about the types of motions you are hoping to see and save accordingly.
