    - Copy a database at a point in time:
      fdm -source key=<source_secret> pit=12/1/2018 -dest key=<dest_secret>
    - Export a database to the directory '/work/export':
      fdm -source key=<source_secret> pit=12/1/2018 -dest path=/work/export
    - Import all JSON and CSV files from the directory '/work/import':
      fdm -source path=/work/import -dest key=<dest_secret>
    - Test import of all JSON and CSV files from AWS bucket and folder:
      fdm -source aws=${AWS_SECRET_ACCESS_KEY} id=${AWS_ACCESS_KEY_ID} \
          region=${AWS_DEFAULT_REGION} bucket=//bucket/load -dest dryrun


When the Fauna Data Manager finds a directory called log in the current directory, it creates a timestamped log file that captures all of the details of a single invocation, and creates a symbolic link to the most recent log file:

$ ls log
fdm.2020-04-  fdm.2020-04-
fdm.2020-04-  fdm.log@

The log files could be useful if you are running multiple invocations of the Fauna Data Manager and need to compare the output between runs. If you encounter an error, the log file would be useful for Fauna support staff.
