Abstract
A method for mirroring data between virtual machines includes intercepting a write command initiated from a virtual machine. Address and data information from the intercepted write command is stored within a queue located within a memory buffer of the primary server. The stored address and data information is transferred, upon filling the queue of the memory buffer of the primary server to a predetermined level, to a dedicated region of the memory of the primary server. The stored address and data information is sent from the dedicated region of the memory of the primary server to a backup server upon filling of the dedicated region of the memory of the primary server to a predetermined level.
