Abstract
A computer program product, system, and method for generating coded fragments comprises generating a plurality of thin differential virtual machine disks (VMDKs) associated with a VMDK; receiving, during a first time period starting after the first point in time, one or more first I/Os to be written from a virtual machine (VM) to the VMDK; writing the first I/Os to a first one of the thin differential VMDKs; receiving, during a second time period starting after the first time period, one or more second I/Os to be written from the VM to the VMDK; writing the second I/Os to a second one of the thin differential VMDKs; and generating a second snapshot of the VMDK for a second point in time after the second time period by applying data written to the first and second thin differential VMDKs to a first snapshot of the VMDK for a first point in time.
