Hard drives will fail!

Manufacturers of hard drives like to boast about “MTBF” (Mean Time Between Failures) and “AFR” (Annualized Failure Rate) rates that indicates that the drive would last anywhere from 300 000 hours (~34 years) to having a likely hood of failing during a year as low as 0,8%.

But real life tests, performed by companies like BackBlaze show that disk drives can fail already after 1 year, actually they had a 5.1% AFR during the first year, 1.4% between 1,5 years to 3 years and a staggering 11.8% between the third and forth year. Their study also shows that after 4 years, it was only 80% of the original disk drives that where still “alive”. Meaning that 20% of the drives had failed after 4 years. 

So, why does this matter?

I have videos, photos and important documents that I need to backup and in some cases archive. Archiving being “removing the local copy and storing the item in a secure place” (think of book keeping, where it’s required to archive the books, it’s not required that you have multiple copies in case of a fire), where as backup is a second copy of the object in another location in case of a fire. We’re talking wedding photos, wedding videos, photos of my son growing up etc. that, in the case of an unforeseen catastrophic event in my home, could potentially be lost for ever!

Companies like BackBlaze offer products for backing up your local machine (and also files stored on a server, like in my case), but I optioned for another setup using Amazon Web Services S3 Glacier!

AWS Glacier

So what is S3 Glacier? Glacier is an archiving service, where you can upload all you data and pay a very small service fee per month for Amazon to keep your data safe. Amazon S3 Glacier is designed to provide average annual durability of 99.999999999% for an archive. The service redundantly stores data in multiple facilities and on multiple devices within each facility. To increase durability, Amazon S3 Glacier synchronously stores your data across multiple facilities before returning SUCCESS on uploading archives. S3 Glacier performs regular, systematic data integrity checks and is built to be automatically self-healing.

My setup consists of a software running on my local NAS that monitors specific places on the NAS where I can put important files and documents, these are then uploaded to Amazon S3 Glacier.

Putting files into Glacier is actually quite easy and the price for storing your data in Glacier is very modest, it’s when you want to retrieve the files that you might need to pay (it also depends on how much data you want to retrieve and how fast you need your files).

As there is no GUI for exploring AWS Glacier Vaults (where the files are stored), I found a really great application online called Freeze that makes life much easier for anyone who wants to explore their files and retrieve them from a UI. 

So are you in the market for a simple, easy to use and very secure way of storing files, documents, pictures, videos etc. of your beloved ones, and you want to be sure that even if your house burns down you will still have access to those files? Try out AWS Glacier with the Freeze App!

Best Screen Capture for macOS

The best tool out there that I have found is Skitch.

Whats great with Skitch, is that it’s awesome to capture screenshots and annotate them right in the app and being able to just copy paste the annotated screenshot to any other application, be it Skype for Business, e-mail or Microsoft Teams. It just works, and what’s even better, it includes free synchronisation of screen snaps to Evernote.

So if you ever look for a great screen snap/screen shot utility for macOS, look no further!

Three finger drag! MacOS Trackpad

Hi future me (and anyone else who stumbled upon this page), this is how you turned on three finger drag:

Yes I know, you thought it was under “Trackpad” in Preferences, but Apple hide this setting under Accessibility.

MacOS Terminal UTF-8 Issue

Since I only tend to do this once every time I get a new MacBook, I decided to document the procedure here so I don’t have to google it every time!

  1. Open Terminal
  2. Open Preferences ⌘,
  3. Goto Advanced
  4. Uncheck “Set locale environment variables on startup”
