摘要
A method for performing a comparison between first and second points in time snapshots of a file system entity, the method may include: (I) receiving by a storage system a command that was sent from a host computer, the command is network file system protocol compliant, wherein the command comprises (i) an operation code, and (ii) information about a virtual path, the virtual path that comprises (ii.a) first fields that comprise snapshot comparison parameters indicative of the first and second points in time snapshots of the file system entity, and (ii.b) a second field of a content that indicates that the command is a request to compare between the first and second points in time snapshots of the file system entity; (II) identifying, by a file system application hosted by the storage system and in response to the content of the second field of the virtual path, the command as including a request to compare between the first and second points in time snapshots of the file system entity; (III) comparing by the file system application the first and second points in time snapshots of the file system entity to provide a comparison result that is network file system protocol compliant; and (IV) sending by the storage system the comparison result to the host computer.
