This situation occurs when the immutability period required by the job within Veeam Backup & Replication exceeds the value set for 'Maximum ISV Controlled Data Immutability Retention' on the target Catalyst Store.
Starting with HPE StoreOnce firmware version 4.3.2, backups stored on a Catalyst Store can be marked as immutable to prevent accidental or malicious deletion. This feature is supported by Veeam Backup & Replication 12. However, to use this feature, the 'Maximum ISV Controlled Data Immutability Retention' setting on the target Catalyst Store must be configured to a value greater than the immutability period needed by the job. If this value is not set high enough, Veeam will attempt to set the immutability period for a file to a value greater than what is allowed by the Catalyst Store setting, which will result in the following behavior:
- For Veeam Backup & Replication 12.0, an error will be displayed, and the job will fail.
- For Veeam Backup & Replication 12.1, the job will complete with a warning explaining that the immutability period of the file was set to the maximum value permitted by the Catalyst Store.
