Please note that if you have a WAL archive available, you may not even
need to have --xlog-method=stream, which is useful to have fully
safe-contailed backups. For the error regarding the missing WAL
segment, it could happen if Postgres completes two checkpoints when
taking the backup. One thing that you could use is a replication slot
that gives the guarantee that segments are retained. Those have been
integrated in pg_basebackup with 9.6.
