I always use a daily cron script/s to setup Downtime schedual to

the flexable downtime, may be better if the hosts always recover
within X min while Fixed is better if you know the host will go down
at X and e back up at Y

Here is a script that I use that schedules downtime for a host/service
You could run it out of your backup pre-script
Modify it for your needs
#!/bin/bash
#
# This script is used to submit downtime to Nagios
# see the usage function for info on how to use it
. /opt/maj/standard
#================================ CONFIG
=====================================
# location of nagios config file
nagios_cfg=/etc/nagios/nagios.cfg
echocmd="/bin/echo"
# get the current date/time in seconds since UNIX epoch
datetime=`date +%s`
author="$0"
#--------------------------------- AUTO CONFIG
-------------------------------
# you should not need to change this
# get the name of the nagios command file
nagios_cmd=`awk -F= '/^command_file/ {print $2}' $nagios_cfg`
if [ ! -p "$nagios_cmd" ]; then
echo "Got Nagios CMD file as \"$nagios_cmd\" and it is not a valid
command file"

Usage: $0 -h HOST -s SERVICENAME -c COMMENT -a "STARTTIME" -b "ENDTIME"
where
HOST is the name of the host that this downtime is for
SERVICENAME is the name of the service that this downtime is for
This is optional. If excluded we schedule downtime for the host
COMMENT is the comment associated with the downtime
STARTTIME format is the same as accepted by the date --date=STRING command
eg "now", "+30 minutes", "6 months 15 day", "2007-09-01
16:00:00"
ENDTIME as for STARTTIME
EOT
