Full system backups with FFS snapshots, ZFS and dump(8)
I am positive not many know that NetBSD FFSv2 allows taking atomic filesystem copies of a mounted filesystem (or part it) through fss(4), the fileysytem snapshot device. These can be used to create backups or to give fsck_ffs a consistent view of a previous version of the filesystem to compare with (see fsck -x). Having a snapshot ready before editing critical configuration files under /etc or performing etcupdates, is also a good idea...
