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"
   exit 1
fi

#================================ FUNCTIONS 
=====================================
#--------------------------------------------------------------------------------
usage ()
{
cat << EOT
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
exit 1
}
#--------------------------------------------------------------------------------
write_to_cmd_file () {
# create the command line to add to the command file
# sample format:
# 
SCHEDULE_SVC_DOWNTIME;mail.optusnet.com.au;SMTP;1188879530;1188880130;1;0;7200;Matthew 
Jurgens;COMMENT

# if $servicename is set it will supply its own ;
cmdline="\[$datetime\] 
$downtime_cmd;$host;$servicename$starttime_sec;$endtime_sec;1;0;$duration;$author;$comment"
 
# append the command to the end of the command file
`$echocmd $cmdline >> $nagios_cmd`
