Stop the clone and retain the recovery evidence
A successful marker check is useful but does not certify application consistency, extensions, roles, large objects or off-host disaster recovery. Record backup label, system identifier, target LSN/name, archive availability, restore duration and observed marker. Recovery time includes provisioning and verification, not just file transfer.
Stop this clone explicitly. Keep its root and log under the owning retention decision; no recursive deletion is part of this guide. Do not expose, promote or redirect clients to it. Clean the source synthetic schema later through its approved rehearsal lifecycle.
Isolated restore host
'/usr/lib/postgresql/18/bin/pg_ctl' -D '/var/lib/postgresql/academy-pitr-20261028/data' -m fast stop
'/usr/lib/postgresql/18/bin/pg_ctl' -D '/var/lib/postgresql/academy-pitr-20261028/data' statusThe clone is stopped; pg_ctl status reports no server running.
