Linux Compare File & Copy Replace if Successful
Hi All,

I have written a shell script that creates a backup of my MySQL database. The script performs the following functions:
  1. Creates a Backup of the MySQL database
  2. Compresses the Backup
  3. Copies the Backup to a Remote Server
  4. Send an E-Mail displaying the size of the Backup
  5. Removes any left over files on the source server not needed.
What the script doesn't do, but what I need it to do:
  1. Check the newly created Backup against the existing backup on the remote server
  2. If the new backup is smaller than the old backup, send a WARNING Notification via e-mail / sms.
  3. If the new backup is larger or equal in size to the old backup, replace the old backup on the remote server with the new backup and then send the successful notification stated in point 4.
Thanks, any help here is really appreciated

Operating systems being used:
Source Server: Ubuntu 12.04.1 LTS
Destination Server: Fedora release 13 (Goddard)

backup_deldump

BACKUP_DELDUMP(8)					       AFS Command Reference						 BACKUP_DELDUMP(8)

NAME

       backup_deldump - Deletes a dump level from the Backup Database

SYNOPSIS

       backup deldump -dump <dump level name> [-localauth]
	   [-cell <cell name>] [-help]

       backup deld -d <dump level name> [-l]
	   [-c <cell name>] [-h]

DESCRIPTION

       The backup deldump command deletes the indicated dump level and all of its child dump levels from the dump hierarchy in the Backup
       Database. Use the backup listdumps command to display the dump hierarchy.

OPTIONS

       -dump <dump level name>
	   Specifies the complete pathname of the dump level to delete.

       -localauth
	   Constructs a server ticket using a key from the local /etc/openafs/server/KeyFile file. The backup command interpreter presents it to
	   the Backup Server, Volume Server and VL Server during mutual authentication. Do not combine this flag with the -cell argument. For more
	   details, see backup(8).

       -cell <cell name>
	   Names the cell in which to run the command. Do not combine this argument with the -localauth flag. For more details, see backup(8).

       -help
	   Prints the online help for this command. All other valid options are ignored.

EXAMPLES

       The following command deletes the dump level "/sunday1/monday1" from the dump hierarchy, along with any of its child dump levels.

	  % backup deldump /sunday1/monday1

PRIVILEGE REQUIRED

       The issuer must be listed in the /etc/openafs/server/UserList file on every machine where the Backup Server is running, or must be logged
       onto a server machine as the local superuser "root" if the -localauth flag is included.
