Abstract
Described herein is a system and method for a scalable crash-consistent snapshot operation. Write requests may be received from an application and a snapshot creation request may further be received. Write requests received before the snapshot creation request may be associated with pre-snapshot tags and write requests received after the snapshot creation request may be associated with post-snapshot tags. Furthermore, in response to the snapshot creation request, logical interfaces may begin to be switched from a pre-snapshot configuration to a post-snapshot configuration. The snapshot may then be created based on the pre-snapshot write requests and the post-snapshot write requests may be suspended until the logical interfaces have switched configuration.
