Claim 11:
12. A networked information management system configured to perform disk usage growth prediction, the networked information management system comprising:
one or more processors comprising physical hardware and configured to:
perform a backup of primary data stored in accordance with an information management policy,
wherein the information management policy comprises a set of parameters for performing backup operations on data assigned to the information management policy,
wherein the primary data is stored in a native format to create a first copy of secondary data stored in a backup format that is different than the native format, the secondary data stored on one or more secondary storage devices;

perform a plurality of incremental backups that backup changes in the primary data to the first copy of the secondary data;
determine usage status data of the one or more secondary storage devices associated with a first portion of the plurality of incremental backups;
for each one of a plurality of prediction models, perform a validation check using the usage status data associated with the first portion of the plurality of incremental backups;
compare validation results corresponding to the plurality of prediction models to a usage status data associated with a second portion of the plurality of incremental backups;
based on the compare, select one of the plurality of prediction models;
using the selected prediction model, generate a disk usage growth prediction of the one or more secondary storage devices; and
based on the disk usage growth prediction, adjust available capacity of the one or more secondary storage devices.
