LinuxQuestions.org - Please critique my backup script

Hey, I just wrote my first backup script and I'd like some suggestions. Especially in the way I access the windows share. Is there a more direct approach than mounting the share separately?
Code:
#!/bin/bash

#Backup User's stuff onto Office share

#This should be run using sudo



destination_user=USER

source=/home/USER

destination_share=//192.168.1.111/User$ #This is a windows share

destination=/mnt/location

backup=$destination/BACKUP



#toggle verbose

#verbose=""

verbose="-v -v --progress"



#Handle backups

backup_suffix="__$(date +%Y.%m.%d-%H.%M.%S)"

backup_pattern="*__[0-9][0-9][0-9][0-9].[0-1][0-9].[0-3][0-9]-[0-2][0-9].[0-5][0-9].[0-5][0-9]"



#connect to the network share

mount -t cifs $destination_share $destination -o user=$destination_user



#FIREFOX THUNDERBIRD PIDGIN

# Mirror these things on the destination, inlcuding deletions.

# No backups are wanted.

options1="--recursive --times --delete-after --no-whole-file $verbose"

rsync $options1 $source/.mozilla/firefox/ $destination/Programs/FF_Profile/

rsync $options1 $source/.mozilla-thunderbird/ $destination/Programs/TB_Profile/

rsync $options1 $source/.purple/ $destination/Programs/P_Profile/



#DOCUMENTS PICTURES SCRIPTS

# Mirror these things on the destination.

# Move deletions/modifications to BACKUP folder and append a suffix.

# Ignores annoying windows system files.

options2="--recursive --times --no-whole-file --delete --backup --suffix=$backup_suffix $verbose --exclude=Thumbs.db --exclude=Desktop.ini"

rsync $options2 --backup-dir=$backup/Documents/ $source/Documents/ $destination/Documents/

rsync $options2 --backup-dir=$backup/Pictures/ $source/Pictures/ $destination/Pictures/

rsync $options2 --backup-dir=$backup/Scripts/ $source/scripts/ $destination/Programs/Scripts/



#MUSIC VIDEOS

# Copy new stuff to destination.

# Leave deletions in place, append suffix.

# Ignores previously backed up files.  Ignores annoying windows system files.

options3="--recursive --times --no-whole-file --delete --backup --suffix=$backup_suffix $verbose --exclude=$backup_pattern --exclude=Thumbs.db --exclude=Desktop.ini"

rsync $options3 $source/Music/ $destination/Music/

rsync $options3 $source/Videos/ $destination/Videos/



#SPECIAL FILES

# Backup these files to BACKUP directory and append suffix.

options4="--recursive --times --whole-file --delete --backup --suffix=$backup_suffix $verbose"

rsync $options4 --backup-dir=$backup $source/Database.kdb $destination/Database.kdb

#rsync $options4 --backup-dir=$backup $source/dat $destination/dat



#disconnect the network share

umount $destination_share
Thanks in advance!
