Plesk Download Backup fails

[PleskBackupDownload-]

Hello

So I have got a problem with downloading plesk backups. My backup has a size of 22GB, and when I click on download, it just hangs there forever. It even happens that PLESK crashes. It seems that during this process (of waiting for the download), plesk creates some temporary file to download? So ... I noticed that even I restart the server, there is some big space consumption since I tried to download that backup.

How Can I download the backup?

How Can I free the space, that Plesk uses when "preparing" the download of the backup?
Obviously there is somewhere some big file laying around.
