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.

摘要： According to an embodiment of the invention there may be provided a method for multi-level disk failure protection, the method may include: calculating first parity information by processing a first data entity that is cached in a cache memory of a storage system thereby providing a first level of disk failure protection; destaging the first data entity and the first parity information to first physical addresses mapped to multiple disks; calculating extra parity information by processing the first data entity, wherein a combination of the first and extra parity information provides an extra level of disk failure protection that exceeds the first level of disk failure protection; and destaging the extra parity information to at least one second physical address that differ from the first physical addresses, the at least one second physical address are included in a spare physical memory space that is not allocated, at a time of the destaging of the extra parity information, for storing data.
