Fortunately, the impact of such a SPOF can be alleviated thanks to two features that Barman provides to increase the number of backup tiers:
How are continous backups performed in PostgreSQL?
Continous backups are performed push-style, where the postgresql server will copy rolled-over WAL files to the backup server via rsync using SSH. Once the files have reached the backup server, barman will periodically (via cron) archive those WAL files to its internal backup catalog.
What’s the difference between PG _ dump and barman?
