## name your backup modules with the path to their ZFS dataset - no leading slash.

# # in this example, template_demo's daily value overrides template_production's daily value.
# use_template = production,demo

# # if you want to, you can override settings in the template directly inside module definitions like this.
# # in this example, we override the template to only keep 12 hourly and 1 monthly snapshot for this dataset.
# hourly = 12
# monthly = 1

## you can selectively override settings for child datasets which already fall under a recursive definition.
#[zpoolname/parent/child]

# # only override the values already set by the parent template, not replace it completely.
# use_template = demo
# you can also handle datasets recursively in an atomic way without the possibility to override settings for child datasets.
