Data storage resource allocation list updating for data storage operations

A non-transitory computer-readable medium storing instructions that, when executed by at least one computing device in a data management system, cause the computing device to perform operations comprising:

• assigning a category code to data management requests that have similar data management resource requirements for performing data management operations in the data management system;
• from a list of data management requests pending in the data management system,
• attempting to perform a first data management request by assigning the first data management request to one or more data management resources in the data management system;
• and
• if the first data management request fails,
• determining at least one data management resource that is at least partially responsible for the failure of the first data management request,
• identifying other data management requests having the category code of the failed first data management request, and
• updating the list of data management requests to indicate that the data management system should not perform the identified other data management requests having the category code of the failed first data management request and wherein the updating of the list of data management requests comprises removing from the list the identified other data management requests having the category code of the failed first data management request.
