'simple' algorithm that can predict disk usage or 'time to be full' Let say I have time series of disk usage of last 30 days..
Given this information and with the assumption that the disk usage 'pattern' isn't changing dramatically over time, what would be a naive/simple algorithm to predict when is disk going to be full?
I'd try fitting a linear model (i.e., assume new data arrives at a constant rate) or an exponential one (i.e., new data is proportional to what is already there), and see which one is better.
