Abstract
An attempt to write to a block of data in a main volume of data is detected. An indicator associated with the block of data is accessed before a copy-on-write operation to a snapshot volume is performed for the block of data. The indicator is used to determine whether the copy-on-write operation is to be performed for the block of data.
