Newer tar apps are compression aware, can call gunzip, gzip, bzip2, bunzip2. The gzip family is happy with stdin/stdout, which makes file names/extensions moot. I have also used cpio, which takes a stream of file names and makes an archive in output mode. You can move a tree of files with no tar file across the network with:

Code:

find * | cpio -oaH crc | gzip -9 |ssh somewhere 'cd target ; gunzip | cpio -idmH crc'

The compression speeds the network passage and encryption, using up to 7 CPUs in pipeline parallel. Low latency, too. I sometimes use compress for less delay or bzip2 for more compression.
