Transfer large files/directories with no overhead over the network

This invokes tar on the remote machine and pipes the resulting tarfile over the network using ssh and is saved on the local machine. This is useful for making a one-off backup of a directory tree with zero storage overhead on the source. Variations on this include using compression on the source by using 'tar cfvp' or compression at the destination via

ssh user@host "cd dir; tar cfp - *" | gzip - > file.tar.gz

What others think

the p switch to tar is not necessary in creation ("c") mode.

Also, dd is not necessary, simply redirecting with "> file.tar" is enough.

remember that * won't capture .dotfiles and .dotdirs/

Comment by linuxrawkstar 332 weeks ago

Why not gzip before downloading?

ssh user@host 'cd dir; tar zcf - .' > file.tgz
