Linux ordinarily uses Cron to automatically perform routine system maintenance on desktop or laptop computers, however not running Cron routinely can result in monstrously large log files and other problems. You can offload most or all of your usual daily and longer-interval Cron jobs onto Anacron enabling your computer to run regular maintenance jobs whenever the computer is powered on, even if those times are unpredictable.
