Goal

This note describes the automated Recovery Appliance Backup and Recovery process.

A background process on the system backs up the necessary EM agent, OSB catalog, and Recovery Appliance catalog information (e.g. backup metadata, protected database/VPC users, protection policies, etc.).

• This process runs every 2 to 8 hours (depending on release and number of racks in your ZDLRA) alternating between compute nodes.

In the event of a complete system failure, this backup is used to recover the Recovery Appliance catalog, along with all users and policies as of the time the backup was taken.

  
Goals of the Recovery Appliance Backup/Recovery process:

• Protected databases should be able to resume their backups as soon as the system is back online, with no changes to database-side configuration
• Protected databases should have access to Recovery Appliance backups (including tape and replicated copies) as soon as the system is back online       
  
  

Further details:

For 12.1 based ZDLRA:

1) The export process is controlled by ra_export.pl;

This covers OSB, EM, and the ZDLRA components (non delta pool backup metadata, protected database users, protection policies, etc..)   

  

2) The import process is part of the racli install appliance;

The automatic exports happen multiple times per day and the export bundles can be copied offsite from here:

/dbfs_obdbfs/OSB/ra_export/

For 12.2 Based ZDLRA:

1) The export process is controlled by ra_export.pl;

This covers OSB, EM, and the ZDLRA components (non delta pool backup metadata, protected database users, protection policies, etc..)

2) The import process is part of the ra_install.pl;

The automatic exports happen multiple times per day and the export bundles can be copied offsite from here:

/raacfs/raadmin/ra_export/

For 19.2 Based ZDLRA:

1) The export process is controlled by ra_export.pl;

This covers OSB, EM, and the ZDLRA components (non delta pool backup metadata, protected database users, protection policies, etc..)

2) The import process is part of the racli install appliance;

The automatic exports happen multiple times per day and the export bundles can be copied offsite from here:
