2 reads that I can recommend, though a bit dated: Bash Programming Introduction and Advanced Bash Scripting.

My suggestion is get the flow of the script down first, without thinking too much about the programming language. Eg.
Code:
for each directory to be backed up
  create an archive of that directory
  if successful
    copy the archive to the backup server
    remove all but the last 7 backups
    send a mail to the admin
  else
    send the error to the admin

On the backup server
Code:
find all backups older than 3 months and remove them

Then, create small parts of the script task by task, eg. create the loop you need, then how to remove all but the last 7 backups, how to copy it to the backup server, ... You won't need much syntax for a script like this, and you should do with these commands: find, scp, tar, mailx.

And 2 days left isn't all that much time, so either you've been slacking off, pretended that you know shell scripting during the interview, or your boss doesn't know what kind of effort really is needed.
