Abstract
Performing snapshot conscious internal file modification for network-attached storage is presented herein. A file system can comprise a first component configured to modify, during a service request, storage for a subset of data blocks of a file—the service request not being recognized by an external entity as a change of content of the file. Further, the file system can comprise a second component configured to prevent, based on the service request, a copy of the storage from being created for servicing of a snapshot—the snapshot comprising a point-in-time copy of the file system.
