I'm having a problem with the virtualmin backup module. Whenever I select ssh as backup destination the backup job hangs. When I select ftp everything goes through in a couple of minutes.
I've tried tracing the processes spawned by /usr/local/lib/webmin/virtual-server/backup.cgi but output stays empty.
The virtualmin 4.16 installation is hosted on FreeBSD 10.1-RELEASEp16.
Does anyone know what's going wrong here? I'd really want my backups to be transferred with scp instead of plain ftp.
