●Preventing File System Event Storage

In some cases, the contents of a volume are sufficiently secret that it is not appropriate to log them. To disable logging on a per-volume basis (for creating a backup volume, for example), you must do the following:

・Create a .fseventsd directory at the top level of the volume.
・Create an empty no_log file in that directory.
So if your volume is mounted at /Volumes/MyDisk, you would create an empty file called /Volumes/MyDisk/.fseventsd/no_log.
