+### CloudDosAbsoluteLimitReachedWithRetry

+**Error message** | `Operation is blocked as the vault has reached its maximum limit for such operations permitted in a span of 24 hours.`
+------ | -----------
+**Possible causes** | When you've reached the maximum permissible limit for an operation in a span of 24 hours, this error appears. This error usually appears when there are at-scale operations such as modify policy or auto-protection. Unlike the case of CloudDosAbsoluteLimitReached, there isn't much you can do to resolve this state. In fact, Azure Backup service will retry the operations internally for all the items in question.<br><br> For example, if you've a large number of datasources protected with a policy and you try to modify that policy, it will trigger configure protection jobs for each of the protected items and sometimes may hit the maximum limit permissible for such operations per day.
+**Recommended action** | Azure Backup service will automatically retry this operation after 24 hours.
