Backups

Hello,

I am new to this list and new to PostGreSQL.

My PostGreSQL  applications will typically be small networks - maybe
from 1 to 5 users.

The data will be on a server, at, say

  E:\PGSQLDATA

I have a question about backups:

Is it ok simply to zip the contents of E:\PGSQLDATA to a zip file and
store this file on a CD or DVD?  I am sure that the data will not exceed
50 Megabytes, so it should fit on a CD.

Is there anything I am overlooking in such a backup procedure?  Will
that backup everything I need to restore (via unzip) in case of emergency?

Thanks,
