Summary :
SAP Note addresses strategies for efficient Oracle database backups using BRBACKUP for large datasets ranging from 100 GB to 1 TB – key challenges include server resource allocation and completion within limited nightly windows. It discusses leveraging hardware-compressed tape units, optimizing backup timing, and employing parallel backups to enhance performance. Strategic advice includes using locally mounted tape devices or direct hard disk backups, avoiding network backups for stability, and incorporating external backup programs via BACKINT for special hardware. The document emphasizes careful planning to mitigate performance degradation during backup operations and secure data integrity.
