Generating predicted usage of storage capacity

A method for storage management, comprising:

• obtaining a feature characterizing a usage of storage capacity for a storage device;
• and
• predicting the usage of storage capacity for the storage device based on the feature and a predictor updated by a method of storage management which includes:
• obtaining a historical usage of storage capacity for a storage device;
• obtaining, for the storage device, raw data associated with the historical usage of storage capacity;
• determining, as a historical feature characterizing the historical usage of storage capacity, a feature in the raw data, responsive to a relevance of the feature to the historical usage of storage capacity exceeding at least one predetermined threshold, wherein the historical feature comprises an average size of data written for the storage device within a predetermined time interval, a physical space size for the storage device used within the predetermined time interval and a timestamp associated with the predetermined time interval, and wherein the timestamp indicates a sampling time point associated with the predetermined time interval;
• generating a predicted usage of storage capacity for the storage device based on the historical feature and a predictor for predicting a usage of storage capacity;
• and
• updating the predictor by comparing the historical usage of storage capacity with the predicted usage of storage capacity.
