Rsync does not have any fault-tolerance or retrying mechanism.  If the
operating system breaks the connection, rsync will abort with exit code
12, while if the OS retains the connection, rsync will just proceed when
the network starts working again.

Write a script that runs rsync repeatedly until it exits with a code
other than 12 (which indicates a broken connection).
