Re: Point in time recovery + replication

Hei,

I think, that it can be done just via RSYNC with stopped both of databases:

Just like in the "Getting it working" part.

Hello Everyone,

I have a primary  / hot standby scenario with streaming replication. Postgres version is 9.1.8. 

A full backup is made nightly on the primary and copied to the secondary, just for backup purposes, the replication is never stopped /restarted.

Supose that for a reason I need to restore the primary to a point in time, let's say just after the last backup. I've done this by:

1) stoping de databese

2)restoring the backup

3) creatng a recovery.conf where I specified a recovery_target accordingly

4) start the database

This works fine on the primary. The quesion is how do I restart the replication on the secondary, on the new timeline?

I tried to restore the same backup on the secondary and starting the continuous recovery, but it starts on the previous timeline.

I also tried to set the recovery_target_timeline in the secondary to the new timeline, but I get an error. Do I need to get a new copy of the primary to continue the replication?
