Alfresco Automated Backup Script Linux

Backups are a pain and as our system is used more and more the need for more regular and controlled backups has been demanding. Doing the system manually for a while has given an idea of where the problems are. We do an automated backup every night of the whole machine, but this does not include an Alfresco database schema and when we have tried to recover the database the solar indexing has made the backups useless.
The basic backup mechanism I have given before, so here is a simple I have been using which works.

I run the script as root and have made a .pgpass file in the root directory with the database password in it.
*:*:*:postgres:topsecret
This file is chmoded at 600

The backup Script for Linux is run by a cron. Each time it is run a new dated backup is made. These are periodically removed as they get to old.
