I decided to try out a free trial of BackBlaze Backup, a cloud backup service for personal computers. The way it works is that you set up an account and install their software and Backblaze backs up your computer to their cloud servers (encrypted) in the background. You can select which files and folders you wish to leave out and it just does its thing. I have 1T of data on my MacBook Pro so at first estimate it was going to take something like 855 days to complete my first backup.

Set Backblaze's throttle as fast as possible (Backblaze system preference /. The first Backblaze backup is relatively slow, but it gets better afterward.

- Mar 26, 2015 – Introducing Threading Threading allows Backblaze to optimize upload and downloads speeds if there is network latency in the internet connection between the computer and Backblaze.

- Backblaze offers a non-optimal form of threading for both uploading and downloading. For uploading, Backblaze threading is enabled by default and it would be painfully slow otherwise, as the software divides up files larger than 30 MB into small 10 MB file chunks and then uploads each chunk separately.

The free trial was only 15 days so I decided to see if I could make it go any faster and they suggest removing Bandwidth Throttling. The throttling settings in backblaze on a Mac are located: Mac Settings > Backblaze > Settings > Performance tab:

We have a Comcast business connection at work and lately the Internet has been running dog slow. I’ve spent a couple days with Comcast on the phone trying to troubleshoot our problem. Finally they had me connect my laptop directly to the modem and all the speed tests turned out fine. I came in this morning and the slow internet persisted and finally it dawned on me– I bet my (unthrottled) Backblaze backup is dragging down everyone at the office. I paused my backup and what do you know–our network returned to its snappy, fast self. Let that be a lesson to me 🙂 Throttled, I’m now back to the 855 day estimate so it’s looking like the online backup isn’t going to work with me, my large amount of data, and slow Internet connections 🙁
