By default, flows are saved to the h2oflows
directory underneath your home directory. The directory where flows are saved is printed to stdout:
03-20 14:54:20.945 172.16.2.39:54323 95667 main INFO: Flow dir: '/Users/<UserName>/h2oflows'
To back up saved flows, copy this directory to your preferred backup location.
To specify a different location for saved flows, use the command-line argument -flow_dir
when launching H2O:
java -jar h2o.jar -flow_dir /<New>/<Location>/<For>/<Saved>/<Flows>
where /<New>/<Location>/<For>/<Saved>/<Flows>
represents the specified location. If the directory does not exist, it will be created the first time you save a flow.
