So, i configured a pbs and i also added proxmox backup client on a standalone machine and tring to take backup from the standalone machine to the pbs and i added this script to the client machine. I create a new user which is called CBackup i added an admin permission to the datastore/JU-BACKUP and the scrip looks like this
export PBS_PASSWORD='ambdk'
export PBS_USER_AND_API_TOKEN='CBackup@pbs!backup'
export PBS_HOST=''
proxmox-backup-client backup root.pxar:/home/Database_Backup/ --repository

saved it as
when i run ./ it keeps saying
Starting backup protocol: Tue Feb 21 11:20:35 2023
Error: permission check failed.

what is the problem??
proxmox-backup-client backup rclient.pxar:/home/Database_Backup/ --repository ip_address:JBACKUP

when i run this command for example it why is asking me to insert the root@pam password when i want to use different user
