1. A method, comprising:
- detecting a write operation on an end user computing system by an agent placed on the end user computing system, the write operation comprising block parameters that define changes to a file, wherein the block parameters are part of a changed set that corresponds to the write operation without actual changed bytes of data of the write operations;
establishing, by the agent, a buffer from free memory available on the end user computing system;
storing, by the agent, the block parameters in the buffer prior to transmitting the block parameters of the write operation to a replication receiver system;
transmitting the block parameters to the replication receiver system from the buffer;
obtaining the actual changed bytes of data using the block parameters; and
transmitting the actual changed bytes of data to the replication receiver system, wherein the replication receiver system creates or updates an incremental file or snapshot using the block parameters and the actual changed bytes of data, so as to allow for near-continuous replication of changes to the file.

Abstract
Systems, methods, and media for efficient file replication are provided herein. According to some embodiments, exemplary methods may include detecting a write operation occurring within an operating system of the computing system, identifying block parameters for the write operation, as well as one or more of buffering and batching the write operation, and transmitting the write operation to a replication receiver system.

15. A method, comprising:
-
detecting a write operation occurring within an operating system of an end user computing system by an agent placed on the end user computing system; identifying, by the agent, block parameters for the write operation; capturing, by the agent, an offset, length, and size of the write operation, rather than capturing the actual write data of the write operation; one or more of buffering and batching the block parameters, by the agent, the block parameters being stored in free memory of the end user computing system; transmitting only the block parameters to a replication receiver system; obtain a snapshot of the end user computing system; obtain the actual changed bytes of data from the snapshot using the offset, length, and size; and transmit the actual changed bytes of data to the replication receiver system, so as to allow for near-continuous replication of changes to files. - View Dependent Claims (16, 17)

18. A system, the system comprising:
at least one server having a memory that includes executable instructions and a processor executing the instructions, the instructions comprising; a filter driver controller communicatively couplable with a filter driver installed in a layer of an operating system of an end user computing system, the filter driver controller executing the filter driver to; detect a write operation on the end user computing system, the write operation comprising block parameters that define changes to a file, wherein the block parameters are part of a changed set that corresponds to the write operation without actual changed bytes of data of the write operations; transmit the block parameters to a replication receiver system; obtaining the actual changed bytes of data using the block parameters; transmit the actual changed bytes to a replication module, the replication module using the block parameters and the actual changed bytes to create or update an incremental file or update a snapshot, so as to allow for near-continuous replication of changes to the file. - View Dependent Claims (19, 20, 21, 22, 23, 24)

25. A system, the system comprising:
-
a filter driver installed on an end user computing device; and at least one server having a memory that includes executable instructions and a processor executing the instructions, the instructions comprising; a filter driver controller, the filter driver controller executing the filter driver to; detect a write operation on the end user computing system, the write operation comprising block parameters that define changes to a file, wherein the block parameters are part of a changed set that corresponds to the write operation without actual changed bytes of data of the write operations; store the block parameters in an activity log; obtain a snapshot of the end user computing system; retrieving the block parameters from the activity log; obtain the actual changed bytes of data from the snapshot using the block parameters; and transmit the actual changed bytes of data to a replication receiver system, so as to allow for near-continuous replication of changes to the file.
