Hello all, One doubt about how PostgreSQL PITR works. Let us say I have all the archived WALs for the past week with archive_command = 'cp -i %p /home/postgres/archive/%f</dev/null' I took a base backup last night. If I try to recover the server today after copying the base backup from yesterday and providing restore_command = 'cp /home/postgres/archive/%f %p' does PostgreSQL go through all the past week's archived WALS or it can figure out that the base backup is from yesterday, so skip a large number of archived WALs and start only from file xxx ?
Yes, It starts out form "where it needs to". Assuming you did a pg_start_backup() before you did your base backup? -- Jesper -- Sent via pgsql-performance mailing list (pgsql-performance@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
