Be cautious about using tar pipes with compression. I've had experiences where the tar pipe will see the tarball being sent over and truncate the inner tarball.

Be cautious about using tar pipes with compression. I've had experiences where the tar pipe will see the tarball being sent over and truncate the inner tarball. The compression in SSH tends to be good enough. My other suggestion for SSH is to change the algorithm used; rc4, while insecure for most things, is normally good enough, if not, blowfish tends to be a bit faster than AES.
