# we are securing this elsewhere; if we are using this method, we'll need to configure the target host
# 'user' needs an authorized and restricted public key for SSH access and sudoer rights on 'remotehost' to execute the following as root:
# /usr/sbin/zfs recv -Feuv datapool/backup, /usr/sbin/zfs destroy -r datapool/backup/*
