With news that PGBackrest being EOL'd I'm interested in hearing that the Enterprise #PostgreSQL Community is thinking about this.

There are a couple companies that have forks. Is this project too important for one company to run and maintain?

I don't know the maintainer, but the messaging is one that I resonated with. They mentioned that they thought someone would fork it. I wonder if the conversation of donating it to a foundation that could try to help with funding and maintenance of it would work?
