For NFS I use automounter:
/etc/rc.conf
# NFS automount
amd_enable="YES"
In case my NFS backup server is down or there is problem with network
then I can start fileserver without manually interacting with fstab to
start up operating system.
Now my backup script can mount filesystems as needed with this script:
#!/bin/sh
# This script does personal backups to a rsync backup server. You will
end up
# with a 7 day rotating incremental backup. The incrementals will go
# into subdirectories named after the day of the week, and the current
# full backup goes into a directory called "current"
# tridge@linuxcare.com
# directory to backup
BDIR=/data/samba
