Whatcha all Windows users using for backup up your main PCs?

I'd like to backup most of my files, but I have less than 15GB  
space free on a 250GB HDD. Can't add an extra HDD/SDD or  
replace the existing HDD at the moment (PC is a bit hard to  
access).

The goal is to send the files to an offsite server, automated.  
But I am not interested in paying for a VPS for that.  I'd like  
to encrypt the files myself and upload a bundle.

I experimented with 7Zip and gpg, but found out that 7zip  
doesn't support pipes.

Is there another rudimentary grassroots way to achieve this?

Since gpg can only input one file at a time, I was thinking of  
building a FOR loop to create a gpg encrypted version for each  
file and pipe that to Winscp.

This is for a Win7 environment, BTW.
