Abstract
A method, system, and computer-readable storage medium for providing an adaptive tap for a virtual machine protection are disclosed. In one embodiment, an Input/Output (I/O) write is received from one of virtual machines. The virtual machines are executed on a server, and each virtual machine is configured to generate I/O writes to a VMFS file system on a primary storage. The I/O write includes data and an offset at which the data is to be stored in the VMFS file system. The server, and primary and secondary storage are coupled to a network. A virtual machine indicator is determined using the offset. A secondary write to a secondary storage is generated based on the I/O write. The secondary write includes the data and the VM indicator associated with the I/O write. The secondary storage is then accessed to write/store the secondary write.
