Abstract: A storage system migrates pages of data based on a determination that the page includes snapshot data. Parameters associated with a page (e.g., a page rank) may be updated based on a determination that the page includes snapshot data. A tiering process may subsequently analyze the parameters to determine whether to migrate the page to a different storage tier. A share-write to a page that is referenced by the snapshot volume and a base volume is utilized to migrate pages that include snapshot data.

Abstract: A storage system periodically replicates data to another storage system for data backup and protection. The storage system is configured to detect an irregularity potentially causing a fault in the storage system. Such a detected irregularity may a component failure in a storage device, a temperature change in a storage device, etc. In response to the detected irregularity, the storage system increases a replication rate of data to the backup storage system.
