It might be possible to use an sftp to ftp bridge, something like:

https://www.bitvise.com/ftp-bridge

Redirecting the ports to localhost on Backup server and then breakout
the secure element to plain old ftp which Backuppc can use directly.

Obviously you may need to lock down ftp access bit by limiting to
localhost chroot etc. Plain text security concerns etc.

There's probably other workarounds you could do with other open 
software like stunnel as aforementioned or ncat or a socks proxy 
of sorts. 

Another idea just came to me as I type this - use sshfs to mount the remote 
sftp to your local
Backuppc system and then just use tar or rsync from the locally mounted drive.
That's probably the easiest if it works.

Caveat, I've never done any of the above but would be curious to know what 
works for you.

Graham

And just as soon I remembered, FTP does not work over one connection 
only. So my guess is that unless they support some other protocol in 
BackupPC, it will not work. Unless you use some external helper scripts etc.
