pghoard basebackup_incoming is keeping old dated folder that is occupying database node disk space

[desorenp]

I have the following pghoard configuration , and should be having only 2 pg_basebackups and noticed that the disk is having multiple old dates pg_basebackups.

Could you kindly suggest the correct configuration how to maintain only the required number of pg_basebackups

pghoard_restore list-basebackups --config /var/lib/pghoard/pghoard.json
Available 'default' basebackups:

Basebackup Backup size Orig size Start time

As per my understanding, pghoard stores the basebackup in a temporary location (/var/lib/pghoard/temp_data/default/basebackup_incoming/2024-10-10_07-25_0/base.tar) , and then uploading it to default/basebackup/2024-10-10_07-25_0 , but when it is trying to delete the temporary location, it is using a different location (/var/lib/pghoard/temp_data/default/basebackup/2024-10-10_07-25_0)

Below is the pghoard.json configuration :

{
    "backup_location": "/var/lib/pghoard/temp_data",
    "backup_sites": {
        "default": {
            "active_backup_mode": "pg_receivewal",
            "nodes": [
                {
                    "host": "127.0.0.1",
                    "password": "pghoard",
                    "port": 5432,
                    "user": "pghoard"
                }
            ],
            "object_storage": {
                "directory": "/var/lib/pghoard/backups",
                "storage_type": "local"
            },
            "pg_basebackup_path": "/usr/bin/pg_basebackup",
            "pg_bin_directory": "/usr/pgsql-16/bin",
            "pg_data_directory": "/var/lib/pgsql/16/data"
        }
    },
    "json_state_file_path": "/var/lib/pghoard/pghoard_state.json"

Could you suggest what's wrong in the configuration?
