I want to check the size, as well as if the backup completed successfully before replacing the old files on the remote server with the newly created files.

This is what my scripts looks like:

Code:
#!/bin/bash
# ===================================================================== #
#  OTRS BACKUP SCRIPT WITH SYSTEM INFORMATION  #
#    SCRIPT CREATED 15/11/2012   #
#               SCRIPT LAST MODIFIED 10/01/2013    #
# ===================================================================== #

# ===================================================================== #
#    VARIABLES THAT CAN BE USED IN THE SCRIPT   #
# ===================================================================== #
# DIRECTORY WHERE FILES ARE STORED
BACKUPDIR="/app/temp"
# CREATES A TITLE VARIABLE
TITLE="OTRS System Status"
# SPECIFY THE CONTENT OF THE E-MAIL TO BE SENT
MAILCONTENT="files"
# SETS THE MAXIMUM SIZE OF THE E-MAIL 4000 = +/- 5MB
MAXATTSIZE="4000"
# E-MAIL ADDRESS WHERE THE E-MAIL WILL BE SENT
# MAILADDR="myemail@mydomain.com myemail2@mydomain.com"
MAILADDR="myemail@mydomain.com myemail3@mydomain.com"

# DEFINE THE E-MAIL BODY
SUBJECTFILE=$BACKUPDIR/sqldump.txt
# CREATE THE FILE TO ATTACH
