Welcome to cron.weekly issue #76 for Sunday, April 16th, 2017.

There are lots of Shadow Broker exploits going around for Linux, Unix, Windows, … while some target older releases, make sure to keep an extra eye out for updates in your distributions. They get exploited really quickly.

This issue is a solid mix of everything; lots of back-up tools as a result of a Twitter questionnaire, new releases for Ubuntu, some security news & new guides.

Have fun!
