gz, tar, bzip etc files can be created through command line controls on any unix / linux type server, you can run those commands either through ssh, an sh job or, if the hoster supports it, through the php system() function.
I think php also supports natively gzip, can't remember.
Those programs are included in most *nix os'es. Search for howtos.
