Abstract

A method for creating snapshots and backups in a virtual computing environment is provided. The method includes writing application output of an application spanning one or more virtual machines as an application consistency group to a writeback cache, wherein the one or more virtual machines are implemented using one or more compute nodes and wherein the writeback cache is implemented in direct attached storage in the one or more compute nodes. The method includes pausing I/O (input/output) operations of the application and marking the pausing, in the writeback cache. The method includes resuming the I/O operations of the application, after the marking and dumping data, according to the marking, from the writeback cache to a data node, as a snapshot.
