Remote backup issue

Currently facing a Backup process killed. Error: 1325 while trying to remotely transfer a website from one VPS to another. I don’t suppose that there has to be a certain level of available storage on the host VPS? I’ve not experienced this issue before in the past andf there’s not a whole lot of information on what it might be. Has anyone encountered this?

You are using normal SFTP or the cyberpanel?
