Death of my Macbook Air

A few weeks ago my Macbook air died. It’s SSD drive went out (and coincidentally Apple issued a notice that they are replacing SSD’s on all new Macbook Air’s a few weeks later.) The main reason for this post is to tell you to BACK UP YOUR DATA. Luckily, I had all my important data backed up in Dropbox and larger files that I don’t want replicated to all machines to Amazon S3/Glacier via the amazing Arq software.

A warning on local backups

To save money, one might find it most cost effective to plunker down $99 for a 1TB USB hard drive and just run Time Machine (on Mac) or Carbon Copy Cloner but really that’s not good enough as an only backup. A fire in your home or theft would wipe out all your precious files and memories.

Dropbox to save the day?

Above, I mentioned I used both Dropbox and Arq. Dropbox is just convenient, drag files to the DB folder—it’s backed up. One might even tell me that now you can store files on Dropbox and choose not to replicate them across all machines (an annoyance in the past) but still, at $40+ a month for 500GB of storage, that’s ridiculously expensive — almost 500 bucks a year!) If you were to put that data on Amazon S3 it’d cost you roughly $8.34 a month.

Amazon S3 and Arq

Amazon S3 is big, fast, and cheap. The problem with Amazon S3 though is that it’s not user friendly. It’s really for developers writing apps to store large amount of data—but Amazon has no restriction on use cases so it’s perfectly fine to use for personal data storage.

I really dig Arq because its a one time fee of $40 and then after that you simply connect it up to Amazon S3 or Glacier and pay for only what you use, forever. Amazon however charges per download and upload of your files and every time you access the files (but we’re talking fractions of a penny, so though it probably does end up being a lot cheaper we really can’t compare the two products.) Here’s Amazon’s S3 pricing chart. The other two great things about Arq is that it can do progressive backups, meaning it only backs up changes over time, reducing your costs and time to upload, and Arq also encrypts your data before placing it on Amazon so even if someone were to break into Amazon’s servers or illegally access your account there, your data is still encrypted from the outside and only Arc (with your password) can decrypt it.

Enter Bitcasa

Saying the above, Arq is probably still too complicated for the average computer user. Simply signing up for Amazon S3 alone and generating an access key is above most people’s heads. I’m sure there’s a lot of alternatives out there but I’m looking for one I can recommend to friends and family. I discovered Bitcasa, a hot local startup with big names behind it offering unlimited storage. I honestly haven’t used it enough to recommend it—nor is the company old enough to gain my trust yet, who knows if it will flounder. But U did ask their support team some questions:

Davita: Hello! Do you have any questions I can help answer for you?

You: hi

i don’t get how this can be infinite

what if I have 100TB to transfer

also do i have immediate access to download it

Davita: Hi there :) How are you today?

I get it, you’re thinking “what’s the catch”

no catch

You: this is not financially viable as a company

Davita: we’re able to do this because of our deduplication process

You: oh ok

do you throttle upload after a certain amount?

Davita: Nope, we do not throttle

You: and where do you store this data?

on amazon s3 or an internal data center?

Davita: Amazon s3

You: what about Amazon Glacier

do you use that or no?

Davita: Currently, no


You: If i upload 1TB to S3 that’s the equiv of paying Amazon $100 a year. So bitcasa is betting that my content will be similar to others so they can make somewhat of a profit

by reducing the upload size on s3

Davita: That’s one way to think about it :)

You: Cool. Thanks for the info!

If this company does go under, they will certianly give you enough time (weeks) to download all your data before hand. If someone actually wants to give it a try let me know how it is.


Start with Dropbox for your small stuff which is a no-brainer (free 2GB on signup) and then find a way to backup your larger data offsite. Try Arq (feel free to comment if you need help with it) or follow other suggestions in the comments.
