In this design, we are not touching any WAL related code. The WAL files will
get copied with each backup either full or incremental. And thus, the last
incremental backup will have the final WAL files which will be copied as-is
in the combined full-backup and they will get apply automatically if that
the data directory is used to start the server.Ok, so you keep all the WAL files since the first backup, right?
The WAL files will anyway be copied while taking a backup (full or incremental),
but only last incremental backup's WAL files are copied to the combined
synthetic full backup.
