The method includes obtaining, by a processor, data. The processor clusters the data into clusters based on similarities of the obtained data across an entire storage stack including: storage infrastructure metrics, file metrics and application dependency taxonomy. The processor performs a random sampling process to sample representative data from each cluster. The sampled representative data are combined to generate training data for processing predictive analytics.
