Subject: snapshot backup with WAL files
Date: Fri, 29 Jul 2011 08:35:21 -0700
Message-ID: <4E32D339.50804@nrc-cnrc.gc.ca> (raw)
Hello Gurus,
I would like to configure our Pg db for OS file system snapshot backup
with Pg WAL files, need to know if would be enough in pg db to call :
|*SELECT* *pg_start_backup*('pitr_backup');
and next take the snapshot and after
pg_stop the backup and close the WAL files . During this time the full
pg db read/writes will continue.
Are any loss of data we should may be aware during this backup procedure?
env :RHES-64 bits with LVM directories, PG 9.0, the db size >150GB
Thank you
Isabella
