Might be! It’s just that having a container like that feels easier than looking after bare-metal secondary db
Maybe I’ll just pg_dump during Nextcloud maintenance window and get into BorgBackup putting the dumps on NAS? If I have to revive the db from the dead, I’ll probably just use the dump anyway, so that’s one hoop less
Out of curiosity (I’m not going to try to change your mind, I just want to check a hypothesis): you’ve heard about the button in the past and this is your opinion of it ; or this post is one of the first times and the only context?
