A system, method, and computer program product are provided for implementing a data protection algorithm using reference counters. The method includes the steps of allocating a first portion of a real storage device to store data, wherein the first portion is divided into a plurality of blocks of memory; allocating a second portion of the real storage device to store a plurality of reference counters that correspond to the plurality of blocks of memory; and disabling access to a particular block of memory in the plurality of blocks of memory based on a value stored in a corresponding reference counter. Access to a particular block of memory may be disabled when the value stored in the corresponding reference counter is not equal to a total number of references to the particular block of memory.
A method comprising:
The method of claim 8, wherein the flag is a most significant bit of the corresponding reference counter.
A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform steps comprising:
A system comprising:
