Mirroring problem with PostgreSQL

["Shashi Kanth Boddula" <sboddula@xxxxxxxxxx>]

Hi,

 

One of my client is facing one issue the with PostgreSQL . The details are as follows .

 

1 . PostgreSQL  version 7.4.8 is running on 2 Linux machine  . One acting as a primary database server and another one is acting as a fail-over (secondary)server .

2. Primar & secondary servers are located at different locations

2.  Using DBmirror utility to mirror the database from primary to secondary .

 

With above setup , the problem is , there is a 1 day delay between primary and secondary in the synchronization . That menas , if a client put a record in the primary , it will sync to the secondary with delay of 24 hours .

 

My question is , for above mentioned requirement , what is the currect way to solve the problem . I would like to know Is there any other way to solve this problem .

 

My idea is to implement DRBD to mirror the database between primary and secondary . But , i want to know can DRBD suite this requirement or not . And , is there any limitation while using DRBD in a WAN environment .

 

 Thanks & Regards,
