I will be using a system that's running Windows XP Pro (SP3) as a backup target, probably using an FTP server, to back up some home and work files -- the computer will be in a remote location (across town).

I would like to have both encryption (in case the computer gets stolen) and compression active on the folders that the data gets backed up to. I would prefer not to Zip the files for various reasons (such as, I don't want to have to mass-unzip them in case the source computer loses a hard drive).

I could tell Windows to compress the files that get written to the folder, and use a third-party folder encryption program, OR I could tell Windows to encrypt the files, but then I would have to use something else to compress them.

(Mode-Z for FTP only compresses the data during transfer, right? Once it's written to the target disk, it will be stored "normally" I think.)

I would appreciate any suggestions anyone has. Thanks.

This bears repeating a third time: make sure to export your certificates to removable media.
See "Best practices for the Encrypting File System"

And you are correct that NTFS does not support compression and encryption at the same time. Given the current low cost of hard drives, why even bother with compression?
