######################################
# This is a sample sanoid.conf file. #
# It should go in /etc/sanoid. #
######################################
## name your backup modules with the path to their ZFS dataset - no leading slash.
#[zpoolname/datasetname]
# # pick one or more templates - they're defined (and editable) below. Comma separated, processed in order.
# # 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 also handle datasets recursively.
#[zpoolname/parent]
# use_template = production
# recursive = yes
# # if you want sanoid to manage the child datasets but leave this one alone, set process_children_only.
# process_children_only = yes
#
## you can selectively override settings for child datasets which already fall under a recursive definition.
#[zpoolname/parent/child]
# # child datasets already initialized won't be wiped out, so if you use a new template, it will
# # 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.
[zpoolname/parent2]
use_template = production
# there are two options for recursive: zfs or yes
# * zfs - taken a zfs snapshot with the '-r' flag; zfs will recursively take a snapshot of the whole
# dataset tree which is consistent. Newly-added child datasets will not immediately get snapshots,
# and must instead slowly catch up to policy over time. Slightly lower storage load.
#
# * yes - the snapshots will be taken one-at-time through the sanoid code; not necessarily consistent.
# newly added child datasets will be immediately brought into policy. Slightly higher storage load.
