Reducing pg_dump & pg_restore times

["C.M. Shivkumar" <shivkumar.cm@xxxxxxxxx>]

Hello all!

I have databases of sizes ranging from 30-60GB that have to be backed-up and restored. I want to reduce the pg_dump and pg_restore times for the same. Can someone throw some light on how to go about it. I have tried tweaking the 
postgresql.conf properties. Though, I am not sure what each property means. If someone could point to a document on the same it would be really helpful.

Thanksalot!
