The fastest remote directory rsync over ssh archival I can muster (40MB/s over 1gb NICs)

This creates an archive that does the following:

rsync (Everyone seems to like -z, but it is much slower for me)

• a: archive mode - rescursive, preserves owner, preserves permissions, preserves modification times, preserves group, copies symlinks as symlinks, preserves device files.
• H: preserves hard-links
• A: preserves ACLs

var tmp = null;

$('###selector###').popover({
        trigger: 'manual',
        title: 'testing',
        delay: {show:500, hide:100}
});

$('###selector###').hover(function(){
        clearTimeout(tmp);
