Transfer data over SSH directly in Truecrypt volume

my problem is this: I have to transfer data from my computer to a remote system that doesn't have an encrypted partition. Because I don't want that the transferred data can be retrieved by forensic tools (and I can't set up an encrypted partition at moment) I thought: - Mount the Truecrypt volume with SSH - With SFTP transfer data directly in the mounted volume - Unmount the volume Is this correct or is it dangerous?
