Mariabackup docs for privileges incomplete / outdated for rocksdb backups

Details

    Description

      OS: Linux Debian-93-stretch-64-minimal 4.9.0-8-amd64 #1 SMP Debian 4.9.144-3.1 (2019-02-19) x86_64

      MariaDB: 10.2.21-MariaDB-10.2.21+maria~stretch-log (binary distribution with plugin-rocksdb)

      mariabackup version: mariabackup based on MariaDB server 10.2.21-MariaDB debian-linux-gnu (x86_64)

      User created according to the info found at https://mariadb.com/kb/en/library/mariabackup-overview/#authentication-and-privileges

      When running mariabackup the following error message appears:
      [..] Obtaining rocksdb checkpoint lock.
      Error: failed to execute query SET GLOBAL rocksdb_create_checkpoint='/data/rocksdb/mariabackup-checkpoint': Access denied; you need (at least one of) the SUPER privilege(s) for this operation

      I will try to grant the SUPER privilege to the user and re-run the backup. Would be great to include that in the docs.

            With the SUPER privilege the backup ran through just fine.

            The documentation has been updated. If we want to change the implementation to require lower privileges than SUPER, then that is now tracked as MDEV-20577.
