# Interval units are 'd', 'h' and 'm' for days, hours and minutes.

# they can also be combined if you for example wants a snapshot taken every 1 and a half days:

# source_zfs_cmd is the command to execute zfs locally.

# The target_zfs_cmd option is the command to use to execute zfs on target machine.

# target_test_cmd, if set, is executed before trying to send any snapshot to remote.

# If target_test_cmd returns a non-zero status the remote is considered to be unavailable
|

# and no snapshots are sent. (A warning is written in the log though)

# NOTE:
|
|
# The command arguments must not contain whitespace characters, due to implementation details.

# Just like any other option this is inherited by file system descendants,

# but if a child has the same target_zfs_target as the parent, the child

# For example: The local file system tank/ROOT will be sent to tank/backup/client/ROOT.
