Its main purpose is to keep a set of daily-created +backup files in manageable size, while still providing reasonable +access to older versions. Specifying a size, file number, or age +constraint will simply remove files starting from the oldest, until +the constraint is met. The distribution specification (exponential, +Gaussian (normal), or Fibonacci) provides finer control of the files +to delete, allowing the retention of recent copies and the increasingly +aggressive pruning of the older files. The retention schedule +specifies the age intervals for which files will be retained.
