Abstract
A method, including defining a snapshot referencing a source partition of a storage volume on a storage device, and receiving a request to write a block of data to the source partition. Upon receiving the write request, a delayed instant copy operation is initiated by allocating a target partition on the storage device and replacing, in the storage volume, the source partition with the target partition. A definition of a condition for completion of the delayed instant copy operation is received, and the delayed instant copy operation is completed upon the condition being met.
