yes, much the same as (but more complicated to understand than)
echo '...' >&2

That most certainly has nothing to do with the '/', because the ping command
is run long before the tar command line is built. What does
/usr/local/bin/check_ssh contain?

All of it sounds like intermittent network failures. What did you say about
the network? WLAN with 20 m of concrete between machines? Broken
cable/switch/multiport repeater? Arp poisoning device? When did this problem
start? What piece of hardware (or software) did you change shortly before?
What does a simple 'ping' say (when run for a while)? A flood ping? A command
line rsync (or tar ... "ssh -l backup $host tar cf - / > /dev/null")?
