For the installation guide I used Ubuntu 20.04 on both the target and deployment machines. It will likely work using Mac OSX for the deployment machine (untested so just a guess) and might work using Windows (with the Linux sub system) as the deployment machine (again untested so even more of a guess)
Configurations can no longer be exported as they were in v1 - they can however be promoted from alpha to production.
A backup strategy must always be in place - minimally that would be to backup the database. One tool to do that is pg_dump. This command must be run as a user with read permissions to the database you intend to back up.
Log in as the postgres user:
su - postgres
Dump the contents of a database to a file by running the following command. Replace dbname with the name of the database to be backed up.
pg_dump dbname > dbname.bak
The resulting backup file, dbname.bak, can be transferred to another host with scp or stored locally for later us
