Question about deleting a backup

Hello, The backup storage is configured on a remote sftp server. Everything works fine, but when you download the backup through the panel, a message comes:

Backup file admin.2025-03-20_18-32-02.tar was retrieved from the remote server and will be available to download for 12 hours.

But the most interesting thing is that after 12 hours and even after two days, the downloaded backup is not deleted. Why is that?
The copy continues to lie in the /backup folder

Hello,

Old backup deleted doing backup process based on number of backups you configured. Try to backup same user manually using v-backup-user.

If not deleted doing backup, as a workaround if you backups stored on sftp, you can create a cron job to delete all files in backup folder every day before backup.

There should be an at created to delete the file in 12 hour
