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.
