Time Machine

Who has ever deleted part of a document that later turned out to be important? Or attempted a system change that made the device un-bootable? Only me? OK, but the Apple Time Capsule has saved me more than a few times. This unobtrusive device sits forgotten next to my Internet Router.

Whenever my Mac comes within range, Time Machine backups are made automatically. These are continuous incremental backups so I can go back in time a few minutes, a few hours or a few months or years and restore previous versions of any file. Or an entire device. It just works.

Amazon Lightsail

Having a server on the Internet is essential for an IT professional.
Searching the market I found Amazon Lightsail to be the best value for the small scale test server I needed. This page is being served from a WordPress instance on a virtual server. I have root access to this virtual server and Amazon takes care of the network, hardware and operating system patching for me. For plain old HTML pages I simply create a sub directory below the WordPress directory and add HTML files. The Apache server that drives WordPress handles these pages just as a standalone Apache server would. I installed the Apache Jena Framework on Lightsail by following the standard installation instructions. This allows me to store data in a TDB triple store and query it using Fuseki. Literally anything I want to test or serve can be accomplished on Lightsail for $4.50 per month. If by some miracle I need to upscale I can buy incremental services and serve up to petabytes per second.
