Question when I run incremental backups from the command line they are not linked to the main backup

hi, as per the title when I perform a command line backup on my ftp storage (I made a script to perform backups every hour) plesk does not connect the incremental backups to the main backup
as you see initial backup ("Backup iniziale") is marked 0B

obviously I'm following the logic of filenames for example
main backup: backup_2208211410.tar
incremental backup: backup_2208211410_2208211415.tar
