default label with variables

[maletin]

i run barman backup all via crontab on different versions.
i would like to configure the label/name for each system in a way, that i can directly see some informations
from barman show-backup like PostgreSQL Version or Parent Backup.
are there already better ideas like barman list-backups --full?

$ grep default_label -B1 /etc/barman.d/vs6.conf
[vs6]
default_label = "version=${PostgreSQL Version},parent=${Parent Backup}"

$ barman list-backups all
vs6 20250316T181347 'version=17004,parent=20250316T175954' - I - STARTED
vs6 20250316T175954 'version=17002,parent=null' - F - Sun Mar 16 18:10:35 2025 - Size: 37.5 MiB - WAL Size: 16.1 KiB

Could you explain a little about the use case of this? I'm not understanding what this "default_label" would be, where it would be placed and what's the use you want to gain from it.

A little more information might help us here.

i have many .conf-files in /etc/barman.d/ for differnt server with different models.
https://docs.pgbarman.org/release/3.12.0/user_guide/configuration.html#server-configuration-pg-basebackup
in this config i wanted to have one line to configure a default_backup_name or default_backup_label.

when i do a single backup with --name BACKUP_NAME, i see in the third column of the output from list-backups-command my BACKUP_NAME.
with this extra information, i can quicker decide on which target-server i should recovery a special backup.
but if i run barman backup all via cron, i see only the hyphen (-) after the backup_id.

show-backup has many nice information, after the backup is done.
it would be helpful, if the backup_name could be automatically adjusted after the backup is complete.
