System, method and a non-transitory computer readable medium for protecting snapshots

摘要

A method for protecting snapshots related to a logical unit, the method may include retrieving snapshots blocks that were destaged in a storage system; processing, by the storage system, the snapshots blocks to provide, by an information protection module of the storage system, snapshots redundancy information; and storing the snapshots redundancy information in the storage system.

1. A method for protecting snapshots related to a logical unit, the method comprises:
retrieving snapshots blocks that were destaged in a storage system prior to the retrieving, wherein the snapshot blocks form snapshots, and wherein the snapshots blocks comprise snapshots data blocks reflecting a content of snapshots and parity blocks, wherein the parity blocks were calculated during a destaging of the snapshots blocks and prior to the retrieving of the snapshots blocks; processing, by the storage system, the snapshots blocks to provide, by an information protection module of the storage system, snapshots redundancy information, wherein the snapshots redundancy information is provided in addition to the parity blocks; and storing the snapshots redundancy information in the storage system.
