Hello,
Kindly excuse my beginner question.
I am formulating a backup strategy for our Production environment.
I use pg_basebackup ( naturally with archive logging ) .
I have successfully tested a full recovery and a point in time recovery at the source server.
I have also tested a full recovery in a secondory server with the backups taken from the source server.
My question is regarding the possibility of a PIT recovery in the secondary server.
- Is it possible to do a PIT Recovery in the secondary server WITHOUT copying over the archive logs from the primary server IF the recovery point lies WITHIN THE RANGE of the logs contained in the pg_basebackup ? In other words is it possible to rollforward within the range of the logs present in pg_wal directory.
- Where does Postgres keep track of the information about which log was archived at what time? Is there a command to get this information from postgres?
- I have not tested this yet, but logic tells me that IF I COPY over the ARCHIVE LOGS from the source to the target server, then PIT Recovery should be possible. Please correct me if I am wrong.
Thank you in advance for your kind answers.
LG
Ram
