'wal-e backup-push' will store a complete backup in S3, which can be
restored using 'wal-e backup-fetch'. And since you are already using
wal-e for log shipping, you get full PITR available.
pg_dump for a logical backup is also a possibility, although with 13TB
you probably don't want to hold a transaction open that long and are
better off with wal-e, barman or other binary backup tool.
