COMPREHENSIVE DATA PROTECTION BACKUP

An inventory of computer resources requiring backup data protection including an estimate of future growth of storage resources along with a set of data retention policies, rules, and outcomes in conformance with business requirements, is created. An architecture for initial ingest of protected data and a backup execution approach is created, based on the resource inventory, a sizing and assumptions of resources and data, and the set of data retention policies, rules, and outcomes. An initial ingest copies the protected data to the backup storage. The initial ingest architecture is transformed to a steady-state ingest phase, by incrementally adjusting the resources based on progress of the initial ingest. Responsive to completing the initial ingest of protected data, a steady-state backup ingest is performed. A validity of the sizing and assumptions of architecture resources is determined and an adjustment to the resources is performed based on the validity determination.
