In that case you don't have to write a script but just do the 
following on the CLI (commandline):

1. Mount the usb drive (if not mounted already)
   $ mount /media/sdb1

2. Mirror files to the usb drive
   $ rsync -av --delete /hom /media/sdb1

3. Unmount the usb drive
   $ umount /media/sdb1

PLEASE NOTE: This would synchronize the destination directory with 
the source directory and you will not be able to restore historical 
data. To get rsync to make proper backups do the following:

   $ DSTAMP=`date '+%Y%m%d'`;rsync -avb --delete --backup-dir 
/media/sdb1/backups/$DSTAMP /hom /media/sdb1/mirror

   $ man rsync
   $ rsync --help
