Tape Archival
Protected databases send backups to the Recovery Appliance, which stores them on disk in the specified storage locations. To reclaim disk space and to create transportable tape backups, business requirements may necessitate archival to tape.
Tape backups are a repetitive task that the Recovery Appliance automates and performs as a background task. The Recovery Appliance administrator configures rules that specify the frequency with which the Recovery Appliance creates tape backups. Because the protection policy is a natural grouping of databases, databases sharing the same protection policy can share the same tape archival requirements.
Recovery Appliance creates tape backups in the compatibility version that matches the greatest compatibility version of any full or incremental backup that contributes blocks to the backup. The database identity information that the Recovery Appliance sends to the media management layer is identical to the information that would be sent if the database were sending the backup. This consistency guarantees that the database for which the backups were created can use them.
