G-Technology, Apple Mac, Bootcamp, Windows and Thunderbolt 3 - a word of caution
Working within the broadly defined field of "Consulting" one gathers a great deal of information, both public and private. All needs to be safely stored and accessible readily. I have always adhered to the maxim: "If your data is not in three places, it's nowhere."
tl;dr version - avoid G-Technology RAID devices if you use Windows on Bootcamp. Full reasons below...
As such, regular backups are the order of the day.
As a consultant, it makes sense to have complete isolation of data from different clients, so there can be no accidents involving sensitive data. One nice clean way to do this is to install a tool such as VirtualBox and then run one Virtual Machine per client. Specific artefacts - such as Visio diagrams, Powerpoint presentations, Word document, source code and so on can then be backed-up to a storage device and the VMs kept isolated and backed up on a sliding window basis - so retain say the last five working days of VM disk images for a client and delete everything before then.
So, we have a model such as:
Storage device | |----Client A | |----Files | |----VMs | |----Client B | |----Files | |----VMs
Not complex, but effective and simple to manage and maintain.
