There are fewer things that can go catastrophically wrong if one has actual offline backups. You have to be a lot more careful about protecting anything attached to the Internet.
I do not agree with this. If a hacker is gaining control of your organizational servers to destroy your Online backups, can't he destroy the offline backups and your database ?
This is not a right justification to encouraging Offline Backups over Online Backups.
If you are worried about storing your online backups through internet on cloud (i do not agree as you can still secure your data on cloud), store it in on a server in your Organizational network and do not push them through internet.
Taking Offline Backups is not the only right way to ensure Reliable Backups.
We are way ahead of the days where you need to face downtime to take backups.
Online Backups are reliable in PostgreSQL.
