1. A backup system for storing a copy of client data, comprising:

  • a persistent storage for storing the copy of the client data; and

    a forecaster programmed to;

    obtain storage use rates of the persistent storage over a prior time period;

    select a first prediction period based on the prior time period;

    partition the prior time period to obtain a plurality of partitioned time periods;

    fuzzify the storage use rates over the prior time period to obtain fuzzified storage use rates over the prior time period;

    apply a higher order fuzzy time series operator to the fuzzified storage use rates over the prior time period to obtain a plurality of higher order forecasting functions;

    calculate a fuzzified forecast for the selected first prediction period using the higher order forecasting functions; and

    defuzzify the fuzzified forecast to obtain a forecast for the first prediction period.
