From all of the appends, it's obvious that there are multiple solutions. Looking at the broader topic, the NIST Cybersecurity Framework is an excellent way to create and manage a resilient data framework. IBM offers many tools to support the 5 phases - Identify, Protect, Detect, Respond, Recover. Going with the IBM solutions, you'll get end-to-end integration for your resiliency. September of last year, IBM Threat Detection for z/OS was released to provide data access anomaly detection. IZBR enables forensics of these anomalies to help determine if they represent malicious behavior. DS8K Safeguarded Copy is definitely a powerful solution for creating protected captures on disk throughout the day, with a standard 7-10 day retention. IZBR enables surgical recovery of nonDatabase data sets from these Safeguarded Copy captures, for the case when the classic backup copies have been destroyed. For longer term retention, WORM tape is definitely more resilient than standard tape as it prevents the data from being overwritten. As shared, there are cases where it's not fully immutable. Then, there's cloud object storage, that enables protected (through S3 object lock) and immutable copies of z/OS data. DFSMShsm, DFSMSdss, OAM and new DFSMScdm (Cloud Data Manager) enable clients to leverage object storage with their existing product suite. No need to look elsewhere.
As always, feel free to reach out for a deeper discussion on the subject.
