Sorry if posting twice, wasn’t part of general when sent and didn’t see it received by group.

  I started an online backup of postgres, tar’d my data folder, copy to usb drive in production
and restored it into my RC environment. Have I missed something important?

Online Backup

psql

checkpoint;

SELECT pg_switch_xlog();

SELECT pg_start_backup('postres_full_backup_June222009');

tar -czvf pgprd01_June22_2009_production.dmp.tar.gz data/

SELECT pg_stop_backup();

Restore

tar –xzvf pgprd01_June22_2009_production.dmp.tar.gz

 

When starting the database I receive many errors that look like the backup was corrupted.


You missed the all-important step of also taking your archived log files to the remote environment and creating the recovery.conf file:
