I've two distant servers I would like to configure async replication between.

Servers are running 9.2.4.

Since 9.0 days I do use script with rsync for transfer. And sometimes the servers get out of sync (due large processing in master database and huge network latency), and I have to reinitialize the standby server.

Lately , this script take about an hour to copy all data (23GB) over the standby server, and I would like to know if there is a more efficient way (perhaps, using pg_basebackup?) to reinitilize the standby server.

I've look in wiki pages and also pg_basebackup, but information on how to get data transfered to the remote standby server is vague.

Or should I run pg_basebackup from standby server, and the PostgreSQL protocol is more efficient than rsync?


Thanks,

Edson
