Question #4

An existing MySQL Database environment has been doing backup and restore in a logical way by using the mysq1dump and mysq1 client utilities.

What two are benefits of using mysqlbackup from MySQL Enterprise Backup in this situation?

  • A. mysqlbackup from MySQL Enterprise Backup allows logical backup with concurrency built in to get faster backup speed and restoration speed.
  • B. MySQL Enterprise Backup provides tape backup integration by default. It has the virtual tape option, which allows backup to tape device directly without extra third-party software integration.
  • C. mysqlbackup can back up tables with the InnoDB engine without blocking. The backup is hot with InnoDB. Together with Incremental Backup, mysqlbackup from MySQL Enterprise Backup shortens the backup windows.
  • D. MySQL Enterprise Backup does not back up system data so that it is much faster.
  • E. mysqlbackup utilities dump the full database into a SQL file, which is imported into the mysql client in single-thread mode. mysqlbackup restores data from physical backups. Physical backup methods are faster than logical methods because they involve only file coping without conversion.
