      Description

      Following report received:

      Hi I think there's an error on:
      https://mariadb.com/kb/en/library/full-backup-and-restore-with-mariadb-backup/
      and likely also affects:
      https://mariadb.com/kb/en/library/incremental-backup-and-restore-with-mariadb-backup/
      This line: "$ mariabackup --prepare --target-dir /var/mariadb/backup/ \
      -user backup_user --password backup_passwd" Should not include the "-user
      backup_user --password backup_passwd" part. The comment from Vladislav
      Vaintroub (2017-10-27 05:13)
      https://jira.mariadb.org/browse/MDEV-14150?jql=text%20~%20%22backup%20prepare%20encryption%22
      "--prepare does not need user, or password, it does not contact any
      server.. , it does not understand --innodb-encrypt-log either, it is not a
      server." explains this. Impact of including the username and password when
      attempting to prepare an encrypted backup is the following error on Ubuntu
      18 / Centos 7 2018-09-27 15:31:53 0 [ERROR] InnoDB: Obtaining redo log
      encryption key version 1 failed (4294967295). Maybe the key or the required
      encryption key management plugin was not found. 2018-09-27 15:31:53 0

      You can try --innodb-force-recovery=6 as a last resort. 2018-09-27 15:31:53

      ... fairly challenging to debug so think best to update the page if
      possible.
