Typical sizes of databases

Configuration database files

Recovery Manager for Active Directory employs the following database files (.mdb):

• Rmad.db3. RMAD configuration database. It contains information on the console configuration, such as the managed Computer Collections, backup creation sessions, etc.

• Backups.mdb. RMAD backup registration database. It contains information on the registered Active Directory and AD LDS (ADAM) backups.

As a rule, the file size for .mdb files does not exceed 10MB.

Reports database files

The Online Restore Wizard provides comparison and restore reports based on per-attribute comparisons of directory objects selected from a backup, with their counterparts in Active Directory® or another backup.

RMAD incorporates Microsoft SQL® Reporting Services (SRS). Microsoft SRS is the new reporting standard, replacing the XML-based comparison and restore reports offered by previous versions. For more information, refer to the User Guide supplied with this release of RMAD.

The size of the reports database file depends on the following parameters:

• Number of the directory objects the Online Restore Wizard has processed.

• Number of the processed attributes.

• Type of the processed attributes.

• Number of the available Online Restore Wizard sessions. Note that the information on all sessions is stored in a single reports database file.

To estimate the reports database file size, use the following empiric formula:

6 x <Number of processed objects> / 1000 [MB]

For example, if the Online Restore Wizard has processed 3,000 objects, the reports database file size will be approximately 18MB.

Typical backup creation times

The backup creation time depends on the Active Directory database size (NTDS.dit file) and the compression method Backup Agent uses when processing NTDS.dit. You can specify the compression method on the Performance tab in the Computer Collection Properties dialog box. For more information, refer to the User Guide supplied with this release of RMAD.

The following table illustrates the typical backup creation times for different compression methods. This table has been obtained for the following configuration:

• The NTDS.dit file size: 3.14GB

• The RMAD computer hardware: CPU 2x Intel® Xeon® 2.8 Hz; RAM 1GB
