Using ‘DeltaCopy’ feature
The ‘DeltaCopy’ feature lets you continue a copy operation after a network failure or connection interruption from the place where the fault occurs and not from the beginning.
Radmin uses ‘DeltaCopy’ automatically when you copy any file to or from a remote computer. For each section of source and destination files, Radmin calculates a control value, and this value (several bytes) is transferred to the other computer and compared. If the sums are equal no data for section is sent over the network and the system examines the next section in the same way until it finds a section that has not yet been copied.
