Hi, In postgresql.conf file we have set the following configuration, wal_level=hot_standby archive_mode=on archive_command='test ! -f /archives/%f && cp %p /archives/%f' max_wal_senders=1 wal_keep_segments=128 and took a base backup using the command, pg_basebackup --xlog --format=t -D /backups/`date +%Y%m%d` This base backup and WAL files from the '/archives' dir are moved to another machine in which the base.rar is extracted into $PGDATA folder and WAL files(9 files) are copied to '/archives' folder. recovery.conf is created under the $PGDATA folder with the command "restore_command = 'cp /archives/%f %p'" and then the postgres db service is started. *The restored database has changes which were done today and missing data from changes did a couple of days before.*
Are you absolutely sure about this? All changes present in the archived WAL *will* be replayed sequentially; it's not possible that an arbitrary subset of changes will be left out. Which PostgreSQL version are you using, and what are the exact contents of the recovery.conf file? For working with backups and WAL archiving I suggest you take a look at "Barman" ( http://www.pgbarman.org/ ).
