Dear all,
I have been playing with PITR on version 8.3 so far, but I need to get it
working on version 8.2.
What is the difference between:
archive_command = on (is this command for 8.2?)
archive_mode = on (This one is for 8.3!)
I need to enable 'archive_mode = on', restart postgres, before I can do the
base backup, is that correct?
In order to bring the standby online I need a trigger file, something like:
can I call the trigger file whatever I want? for example;
'/var/log/postgres/postgresql.8.2.trigger'
Postgres 8.2 config
Master:
Postgresql.conf
archive_command = on
archive_command = 'cp -i %p /mnt/pitr/%f </dev/null'
archive_timeout = 60
# mkdir /mnt/pitr
# chown postgres: /mnt/pitr (this will be an NFS mount point)
# mount -t nfs fnsserver01:/pitr /mnt/pitr
# service postgresql restart
# su - postgres
# psql -U postgres
SELECT pg_start_backup('pitr_backup');
\q
# Tar -cvf pg_data.tar /usr/loca/pgsql/data
# Psql -U postgres
SELECT pg_stop_backup();
# cp pg_data.tar /mnt/pitr
Postgres 8.2 config
StandBy:
# Compile pg_standy from the contrib/ folder
# cd /usr/local/pgsql
# rm -rf data/
# tar -xvf /mnt/pitr/pg_data.tar
# chown -R postgres: data
# cd data/
# cd pg_xlog/ - delete the content
# cd ../data
# touch recovery.conf
restore_command = 'pg_standby -l -d -s 2 -t /var/log/postgres/
postgresql.8.2.trigger /mnt/pitr/ %f %p %r 2>>pitr_standby.log'
Postgresql.conf
#archive_command = off - disabled and commented out
#archive_command = '' - disabled and command removed
# archive_timeout = 60 - disabled
Is this correct, am I missing something or anything here isn't correct?
If anyone could give me some light with this it would be very much appreciated.
Thank you very much
Renato
