From what i've found, it seems to valid for mountpoints with spaces in any of the directory structure segments.

With this code, only the first part of a path with a space will be read, and will be missing in the tempfile all together.
Code:
df -h | grep sbl| awk '{print $5}' > /home/greg/fs.out

So, one could remove awk alltogether, but then read the file differently:
Code:
while read _ _ _ _ _ line

Specialy since the 5th variable is only the percentage used, we only name/use the 6th variable, which will include any later variable (path with spaces) as well.

Did some other small changes.
Hope this helps
Code:
#!/bin/bash
#set -x
#
#	Variables
#
	TMP=$HOME/tmp/${0##*/}-fs.out
	HOSTNAME="${HOSTNAME:-$(hostname)}"
	# This will print nothing on my system
	SEARCH="sdb" ## sbl sdb
#
#	Function
#
	check4missing() { # VALUE
	# Compares the current date versus the latest found backup dir
	# Returns false if today's date is not found
		fdate=$(date "+%Y-%m-%d")
		latest_bkp=$(ls -l |grep -v snapmirror | tail -1|awk '{print $9}')
		bkp_fldr_timestamp=$(echo "$latest_bkp"|cut -f3 -d .|cut -f1 -d _)
		if [ "${fdate}" != "${bkp_fldr_timestamp}" ]
		then	return 1
		else	return 0
		fi
	}
#
#	Action
#
	df -h | grep $SEARCH > "$TMP"
#
#	Display
#
	if [ -s "$TMP" ]
	then	# Tempfile has content
		while read _ _  _ _ line
		do 	
			this_snapshot="${line}/.snapshot"
			if [ -d "$this_snapshot" ]
			then
				cd "$this_snapshot"
				if check4missing
				then
					echo "Today's backup is missing for $this_snapshot on $HOSTNAME"
				else
					echo "File system backup has been taken for $this_snapshot on $HOSTNAME"
				fi
			else
				echo "snapshot directory not found on \"$this_snapshot\""
			fi
		done < "$TMP"
	else	# Tempfile is empty
		echo "No netapp filesystems found"
		exit 1
	fi
	rm "$TMP"
	exit 0

NAME

       amanda-scripts - Configuring and using the Script API

DESCRIPTION

       The Script API is a flexible system for invoking user-supplied scripts at various points in the execution of Amanda. This manual page
       describes the operation and configuration of the API. For help writing Script API scripts, see http://wiki.zmanda.com/index.php/Script_API.

SCRIPTS

       This section lists the scripts included with Amanda, see the individual man page for instructions on using them. For complete How-To
       information, consult the Amanda wiki at http://wiki.zmanda.com.

       o   amzfs-snapshot(8), - create/destroy zfs snapshot.

       o   script-email(8), - send email.

       Script properties work just like application properties: they are insensitive to case, and - (dash) and _ (underscore) may be used
       interchangeably.

SCRIPTS OUTPUT PROPERTY

       A pre-dle-amcheck, pre-dle-estimate or pre-dle-backup executed on the client can output property on stdout that are sent to the
       application. If the output line matches "PROPERTY str1 str2", Amanda sets a property called "str1" by the value of "str2", that property is
       sent to the application.
