# explains that
# SolrCloud Backup/Restore requires a shared file system mounted at the same path on all nodes.
# This script uses the old Solr Backup/Restore procedure, which is useful if you don't have
# access to a shared disk.
# Requires that the target collection is already set up, with identical number of shards/replicas.

Also, a MacBook with a TouchBar doesn't have the power button anymore. With the following guide you can lock the screen by starting the screensaver, keeping the monitors running.


Set System Preferences » Security & Privacy » General » Require password immediately after sleep...

The simple way

  1. Download and unzip it to $HOME/Library/Services/
