# doRemotePing is called only at the end of the script IF $globalSuccessStatus is true.
# This style of pinging is useful as an 'all-or-nothing' approach:
#   all steps of the script MUST be successful otherwise this backup is considered failed.
#
# This functionality is useful for monitoring via platforms like `https://healthchecks.io`
#
# Note that doRemotePing does not check the status of $globalSuccessStatus.
#   It is caller's job to check that.
