Typically they are tiered. There'll be a near-line HDD array. This is for the recent content and content they profile as being common-access. Then there'll be a robotic tape library. Any restore request will go in a queue annd when an arm-tapedrive becomes free they'll seek to the data and read it into the HDD array. Waiting for a slot with the robot arm - tape drive is what will take 4 hours. EMC(kinda), Fujitsu etc…

Wouldn't there also need to be a lot of logic to prevent fragmentation? You'd probably want data from one user near other data from that user, i.e. on the same tape.

Given it takes 3.5-4 hours to retrieve a backup before you can download it, probably not.

I just started a project where I'm keeping a raspberry pi in my backpack and am archiving a constant stream of jpgs to the cloud. I've been looking at all the available cloud archival options over the last few days and have been horrified at the pricing models. This is a blessing!

Great idea, have you got any more details?

Can anyone make sense of the retrieval fees? Seems like the most confusing thing ever. If I'm storing 4TB and one day I want to restore all 4TB, how much is it going to cost me?

1 x retrieval request per archive (it's really designed to store a small number of large files/tars) plus $0.12/GB... therefore, 4TB = $480.

What I find fascinating with Amazon's infrastructure push is the the successful 'homonymization' of their brand name Amazon. Amazon simultaneously stands for ecommerce and web infrastructure depending on the context. e.g "Hey I want to host my server".. "Why don't you try Amazon". "Do you know where I can get a fair priced laptop?" "Check Amazon". Is there any other brand that has done this successfully? Edit: I shou…

In India, the Tata and Birla groups come to mind. The Tatas[1] particularly so. Both are family owned conglomerates and have been around before India gained Independence from the British.

The Japanese Keiretsu[2], from what I have read, is similar. The companies are somewhat loosely connected, but are connected nevertheless.

I'm a long time user of backblaze, and I'm a big fan of the product - it does a great job of always making sure my working documents are backed up, particularly when I'm traveling overseas, and my laptop is more vulnerable to theft or damage. With that said - Backblaze is optimized for working documents - and the default "exclusion" list makes it clear they don't want to be backing up your "wab~,vmc,vhd,vo1,vo2,vsv,v…

With large volumes the real issue is not the storage but the upload speed. I've done some experiments and with the Comcast link (20Mbps down/whatever up), I got 1 Gb/hour upload rate. So, it'll take 11 full days to upload 256 Gb. Or, more realistically, if you do it overnight (8 hours) - the entire month.

GE (aka General Electric) is probably the archtype for this type of diversification.

Virgin has been already mentioned, but is a really interesting example. It really is just a brand - there is no single controlling company.

Home-use is probably the only situation Glacier is good for backup though. A home user is fine with a 3.5-4 hour window before their backup becomes available for download (as it will probably take them days to download it anyway). In a corporate environment, I don't want to wait around for 3.5-4 hours before my data even becomes available for restore in a disaster recovery situation. Seems good for archive-only in a…

Here, we are producing logs of simulation runs that may be needed in the next couple of years. Most of the logs will be destroyed unused. This is a perfect use case for glacier. We do not care about 5 hours recovery time.

How do you think they could use this service? I can't think of a use case for them.

They store the last 30 days worth of versions of every file you modify. Dropbox could keep versions from the last 10 days in S3 but move the rest to Glacier. Restores for older versions wouldn't be instant, but if S3 storage is a nontrivial expense for them moving the bulk of previous versions to Glacier would cut down on costs.

And 30 days is only for free accounts.

Packrat is a Dropbox Pro add-on feature that saves your file history indefinitely.
