Thanks for the clarification. Now I know, that I’ll stick to my daily cronjob that just runs pg_dump via ssh to another machine. I get e-mail notifications with my simple shell script as well.

Can you explain to me how the core backup process works? I browsed the git repo, but could not find it after about 10 minutes.

For example PostgreSQL: does it just do a pg_dump of a whole database? Or table for table? What about incremental backups? Are these implemented? And if so, what’s the concept behind it?

Otherwise I would not see any use for larger (dozens of gigabytes and more) databases.
