The right direction for backups?

Hi there,

I need to implement a routine backup procedure for PostgreSQL 6.5 under RedHat 6. I would like to save and restore a
databasecomplete with all its elements (tables, indexes, etc), all user privileges and group information. 

Can someone please point me in the right direction?
Any help is much appreciated.

Thanks in advance,

J. Alvarez.
