Abstract
Techniques for processing operations may include: receiving, at a data storage system from a host, an operation requesting to perform an offload copy operation internally within the data storage system, wherein the operation indicates that the offload copy operation copies data from a source interval to a destination interval; inserting a record in a log file logging the offload copy operation; inserting a source node representing the source interval in a source interval tree, wherein each node in the source interval tree represents a source interval of an offload copy operation having a corresponding record in the log file; inserting a destination node representing the destination interval in a destination interval tree, wherein each node in the destination interval tree represents a destination interval of an offload copy operation having a corresponding record in the log file; and returning an acknowledgement to the host regarding the offload copy operation.
