If the WAL is not archived and if losing the primary without having access to the current WAL then data loss would
result. A way to avoid the scenario is with an HA solution that involves synchronous replication thus any committed
transactionwould exist on multiple nodes.
I’m not familiar enough with pgbackrest to offer much help there; but it seems like a backup issue as you are losing
filesand directories with a given backup set.
