Barman full Backup is not getting triggered

Question

Barman full Backup is not getting triggered. Installed Barman 2.3-2 in Ubantu 18.04 . Barman is taking incremental backup perfectly but it is not taking full backup.

Barman backup command show below output ,

Backup start at LSN: 
This is the first backup for server h8
WAL segments preceding the current backup have been found:
        from server h8 has been removed
Starting backup copy via rsync/SSH for 20220613T132933 (5 jobs)

Answer 1

When you install barman, you get a cron job in /etc/cron.d/barman that runs barman cron every minute.

That command, however, does not take any backups.

So, it's up to you to add the barman backup server_name --wait command in a cron of your choice (you can actually use the same /etc/cron.d/barman file if you so desire).

That has been discussion that barman cron should take backups according to the retention policy defined, but it actually doesn't, it just deletes existing backups according to that policy, but doesn't take them. See here.
