in our environment, we have a full backup of directory PGDATA and every 15 minutes we do archival backup where there are archival file.
So we can restore in a specific time. Before the archival backup we forced switch wal file to generate archival file so we don't lost any transaction.

In order to be able to do PITR you need: - a base backup of your database - WALs from the backup going on
See <https://www.postgresql.org/docs/12/continuous-archiving.html>. Then, to keep it simple, if the disaster happens in the time window between the backup and the last WAL archiving, you can restore an instance at any point in time previously the disaster itself.
