Deletion of old backups

[MyUncleSam]

Hello,

I am using the docker image to backup my databases. This works fine but I discovered that it is not deleting old backups. I hope someone can help me to configure it properly.

Right now I set it up to keep backups for 31 days and I thought it should be automatically be deleted after 31 days. At the moment it is not the case and I have all the backups of the last 6 months.

My settings:

CONTAINER_ENABLE_MONITORING: FALSE
BACKUP_JOB_CONCURRENCY: 3
DEFAULT_CHECKSUM: SHA1
DEFAULT_COMPRESSION: ZSTD
DEFAULT_BACKUP_INTERVAL: 60
DEFAULT_BACKUP_BEGIN: "+0"
DEFAULT_CLEANUP_TIME: 44640
DEFAULT_ENCRYPT: FALSE
ENABLE_NOTIFICATIONS: TRUE
NOTIFICATION_TYPE: CUSTOM
NOTIFICATION_CUSTOM_SCRIPT: /files/notify.sh
DEFAULT_BACKUP_LOCATION: FILESYSTEM
DEFAULT_CREATE_LATEST_SYMLINK: false
DEFAULT_FILESYSTEM_PATH: /backup
DEFAULT_FILESYSTEM_PATH_PERMISSION: 755
DEFAULT_FILESYSTEM_PERMISSION: 644
