How Recovery Appliance Manages Storage Space

An important duty of the Recovery Appliance administrator is planning for the proper amount of disk space for a specified retention window and database size. As conditions change, the Recovery Appliance provides space management monitoring and alerting at the storage location and database level. When estimated storage needs are approaching the amount of available storage, alerts and warnings give the administrator time to accommodate the storage demands.

The following attributes, whose settings are accessible through the RA_DATABASE view, determine how Recovery Appliance manages storage space and backup retention:

• Recovery Window Goal

• Reserved Space

• Guaranteed Copy

• Maximum Retention Window

• Recover Window Compliance
