These methods include physical backups with MySQLs Enterprise mysqlbackup tool, MariaDBs mariabackup tool, or Perconas XtraBackup tool. Current backup technology utilizes disk-to-disk backup technology, which is considered to be reliable and will have a faster recovery time than tape, so this would not be a concern. Yeah, old. Furthermore, logical backup schemes often take advantage of filters - excluding certain files from being backed up. Logical backups can be imported into a different database, even on a different platform. b) provide direct access to the underlying storage. You can use Oracle Data Pump to export logical data to binary files, which you can later import into the database. A differential backup is a backup that continues to back everything since the last FULL BACK up and once a new FULL BACK up is created the differential backup will start from that point. With logical backups, you can backup a selected set of data (saves time and storage).
