METHOD AND SYSTEM FOR ACCESS-RATE-BASED STORAGE MANAGEMENT OF CONTINUOUSLY STORED DATA |
摘要 |
A method and system for access-rate-based storage management of continuously stored data are provided, the method comprising the steps of: deciding an access weight dependent on an access rate for a data snapshot at a time point in continuously stored data stored in a storage system; determining whether the access weight reaches a first threshold and whether a full copy of the data snapshot at the time point is present in the storage system; and, storing a full copy of the data snapshot at the time point into the storage system when the access weight reaches the first threshold and a full copy of the data snapshot at the time point is absent from the storage system.
