The other day I looked at backing up our extensive local home storage. We don’t have the most, but we definitely have more than most. In aggregate we have about 8TB of local storage. For photos and important docs we use Dropbox, but that only gives me 1TB of online backup.

So when I found out about backblaze’s unlimited backup for only $60 per year, I jumped at the opportunity to try it for free. However, there was one issue, I am on an asymmetric internet connection and at a max of 6Mbps upload connection my back up of 8TB would take a long time, a very long time.

Like all journeys, they start with the first step and this one started with the first upload. The setup of backblaze was easy and it all went smoothly. Within minutes my backup was humming along and I “set it and forget it”.

A few days later I checked my bandwidth consumption and noted a huge uptick. I hadn’t calculated how much it would cost me in bandwidth since at 6Mbps I thought it was too slow to have an impact. Well, I was very wrong.

It turns out that at a steady connection of 6Mbps can consume, on average, about 60GB (yes, Bytes) of data per day. With a cap of 1TB per month, you can consume all of your month’s data just backing up at a mere 6Mbps in half of that.

What’s the moral of the story? Two things; your monthly cap includes uploads and downloads. Even a slow upload connection, when used steady, will utilize a lot more data than you expected.

Considering my cap of 1TB and my average monthly consumption of about 500GB of monthly data prior to my utilizing backblaze, I need to set my backblaze backup upload connection to about 1.5Mbps and hope not to go over my cap.
