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.
