Hi All;
I'm setting up PITR based backups on a production db server.
When the script runs the pg_start_backup it takes forever, like 30minutes+
I can run a checkpoint while waiting for it to complete and it finishes
almost immediately
For now we're executing the start backup like this (in the automated
base backup script:
echo "checkpoint; select pg_start_backup('$tag'); checkpoint;" | psql
we tried it like this and id did not help:
echo "checkpoint; select pg_start_backup('$tag');" | psql
so we added the checkpoint after the pg_start_backup command
Next I'll try this (I assume the first checkpoint is simply un-needed):
echo "select pg_start_backup('$tag'); checkpoint;" | psql
However, this works well and the pg_start_backup finishes in less than
1minute,
but if I leave the checkpoint command(s) out then we're back to
30minutes or more for the pg_start_backup...
We're running version 9.2.4 on a Centos 6 server
Thoughts?
Thanks in advance
