Abstract
Copying data from a source storage system to a target storage system includes resetting a write tracker on the source storage system to track writes to the source storage system by one or more host computing systems, copying data from the source storage system to the target storage system after resetting the write tracker, suspending writes to the source storage system after copying the data, and copying data portions of the source storage system to the target storage system that are indicated as being written by the write tracker after suspending writes to the source storage system. Applications that write data to the source storage system may be quiesced in connection with suspending writes to the source storage system. Data portions may be repeatedly copied from the source storage system to the target storage system until an end condition is reached.
