Data Domain Backup and Recovery Solution
Introduction Backup and recovery solution for Oracle Backup and recovery solution for SQL Server Storage and file system Mtree and storage unit IP network design RMAN backup and restore parameters Test methodology and results Use Case 1: First full backup of standalone OLTP database Use Case 2: Second full backup of the standalone OLTP database Use Case 3: Restore and recovery of the OLTP database from full backup

Mtree and storage unit

  • We created one storage unit on the Data Domain system to use with the database application agent on the database server to back up the database files, as shown in the following example: 

    Figure 15.      Storage unit rman created on DD9300 for backup and recovery testing

    The storage units are shown as a logical partition of the Mtree file system:

    Figure 16.     Storage units seen as logical partitions of Mtree file system

    To implement the Oracle optimized deduplication feature in a Data Domain system, we set the value of the app_optimized-compression option to <user_name> on the Mtree with this command: 

    mtree option set app-optimized-compression <user_name> mtree <storage_unit_name>

    For example, we ran these commands in the command line on the Data Domain system for storage unit rman:

    $mtree option set app-optimized-compression oracle1 mtree rman
