Help with Backup Shell Script

Hi,

I am a linux newbie and I dont have any knowledge on scripting but this is my urgent requirement. I am suppose to write a backup script for 2 of my servers, could someone help me out please. below is my requirement

Mail Server 1 : 10.0.0.1 Mail Server 2 : 10.0.0.2 Backup Server : 192.0.0.1

1. Mail Server 1 & 2 must take daily backups of /var and /etc and store them locally.
2. These backups must be moved to Backup Server on daily basis, once the above local backup is done.
3. Mail Server 1 & 2 must store backups for 7 days and later remove them.
4. Backup Server must store backup for 3 months and later remove them.
5. Files must be stored in tar.gz format.
6. I need the script in such a way that I can add directorys in future.
7. Once the backup is performed, need to send a confirmation mail that its been completed successfully to admin@xyz.com

Also I would like to know what are the important directories we should consider backing up in a mail server. Can you please give me inputs on backup procedures.

Thanks a lot !!!

BACKUP_DELVOLSET(8)					       AFS Command Reference					       BACKUP_DELVOLSET(8)

NAME
backup_delvolset - Deletes one or more volume sets from the Backup Database SYNOPSIS
backup delvolset -name <volume set name>+ [-localauth] [-cell <cell name>] [-help] backup delvols -n <volume set name>+ [-l] [-c <cell name>] [-h] DESCRIPTION
The backup delvolset command deletes each volume set named by the -name argument, and the volume entries each contains, from the Backup Database. The backup listvolsets command lists the volume sets (and their volume entries) currently defined in the Backup Database. CAUTIONS
Deleting a temporary volume set is possible only within the interactive session in which it was created. Exiting the interactive session also destroys the temporary volume set automatically. OPTIONS
-name <volume set name>+ Names each volume set 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 volume set called user and all volume entries in it: % backup delvolset user 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. SEE ALSO
