These log entries mean that some node is requesting a WAL segment that was already removed from
the server.

These are related to the backup not finding that segment, so it means you'll need to resync
your backup stream. I assume that you're using barman and using https://docs.pgbarman.org/release/3.9.0/#streaming-backup .
Hope it helped.
