Обсуждение: Backup Database

I have two Postgres databases (7.4 and 8.24) within the same network on 
LINUX platforms. Data sources go to both databases.

I'd like to set up one as a near real-time backup to the operational 
database.  Is it possible to incorporate a trigger upon update (or 
insert) on the operational 8.24 database to initiate an update (or 
insert) on the backup 7.4 database? 

How do most people set up a near real-time backup database?  Perhaps 
there is something else that acts like a trigger.  Any suggestions would 
be helpful.

Thanks.  Joanne

You can do this with Slony, assuming nothing else needs to be written
(on the replicated tables) into the 7.4 system.

Hi

We do it with Skytools. In addition to replication with Londiste it hs lot's of other useful scripts for keeping online database small and healthy.
