A method, comprising: automatically discovering servers running instances of an application; automatically discovering storage devices associated with each instance of the application; receiving a request to perform a snapshot of data associated with an application running on multiple servers; instructing I/O Freezers on different servers to freeze data requests from instances of the application running on the servers; determining whether the I/O Freezers have frozen the data requests; after determining that all of the I/O Freezers have frozen the data requests, instructing the I/O Freezers to initiate snapshot processing on the data associated with the application so that the I/O Freezers perform the snapshot processing within the same window of synchronization; determining whether the I/O Freezers have initiated the snapshot processing; and after determining that all of the I/O Freezers have initiated the snapshot processing, instructing the I/O Freezers to no longer freeze the data requests.
