Abstract: A method and system for adaptive data transfers with limited resources are described. A data storage system performs operations that include migrating data from one set of storage volumes to another set of storage volumes using a number of data streams managed by a storage controller. During this data migration process, the storage controller can measure performance of the data storage system such as the CPU load, memory usage, network bandwidth usage, and the total number of data streams in use. Based on the measured performance and scheduling information, the data storage system can adjust the number of concurrent data streams dedicated to data migration in order to complete the migration process in a timely fashion without substantial undue impact to client accesses and backup operations.
