title: mariabackup restoring a single database without affecting other tables
body: <p>I'm currently using MariaDB 10.3.17 on CentOS 8 and I'm trying to restore a backup of a specific database. I made 2 dummy databases named <strong>test</strong> and <strong>test_restore</strong>. I updated <strong>test_restore</strong> then created an incremental backup with <code>--databases="mysql test_restore"</code></p>
  
  <p>I ran:</p>
  
  <pre><code># mariabackup --prepare --target-dir=&lt;dir&gt;/mariadb/backup/2020-02/18_10h_full/
  
  # mariabackup --prepare --target-dir=&lt;dir&gt;/mariadb/backup/2020-02/18_10h_full/ --incremental-dir=&lt;dir&gt;/mariadb/backup/2020-02/18_10h10m_inc/
  
  # mariabackup --copy-back --target-dir=&lt;dir&gt;/mariadb/backup/2020-02/18_10h_full/
  </code></pre>
  
  <p>After that, I lost all data on my <strong>test</strong> db but kept my updated <strong>test_restore</strong> db</p>
  
  <p>I can do a full backup and restore with the incremental back up of ALL databases altogether but thats gonna take a long time. </p>
