I’m learning on postgreSQL(9.0.1) especially pg_rman(1.1.2) these days…

What I’ve done is …..

create two tables t1, t2;
pg_rman installation.
pg_rman init -B $RBACKUP_PATH
pg_rman validate -B $RBACKUP_PATH
drop tables t1, t2;
pg_ctl stop -m fast
pg_rman restore -B $RBACKUP_PATH

everyting works fine but…
When I starts up postgresql server process…. some sort fo messages are there like:

cp: cannot stat `/postDATA/ARCHIVE_LOG/00000007000000000000000E': No such file or directory

Anyway, if everything is working well, t1, t2 tables which I created before taking full backup must be there, Am i right? If so, my scripts are bellow…

The problem here is that you restore the backup completely. This means that you actually restore to the point to after the tables have been dropped.

You can see that from the lines:

INFO: validate: 2012-08-14 09:46:37

and

LOG:  last completed transaction was at log time 2012-08-14 09:59:05.321848+09

This is probably due to the fact that you still have your archive logs left in the directory.
What you need to do is either remove everything in /postDATA/ARCHIVE_LOG/ before doing the restore/startup of the database (here I assume that pg_rman archives all archive logs needed for the restore into the backup directory), or you need to modify the recovery.conf file and add a timestamp up to which point you want to restore (which should be a time before the drop), and add the parameter recovery_target_time.

pg_rman is supposed to support adding that automatically if specified, but I am not certain if that works as intended.
