The biggest shortcoming I see compared to the other big players (AWS, Azure, Google), and it is something they don't mention, is that they only have one datacenter, compared to the several from the other big players. The pricing is quite incredible though. I suspect if enough people hop on board with this they will probably look into setting up another datacenter.

Something to note: Unless you're storing data in us-east-1, all other regions in AWS are "one datacenter". Yes, they have AZs, but those aren't datacenters, they're just compartmentalized segments of the same datacenter. So! If you can tolerate the loss of a datacenter, store in Blackblaze. If you need geo-redundancy until Backblaze can offer it? Store in us-east-1 (which is geo-redundant between Virginia and Oregon)…

what about Ireland? Amazon have 7 active Datacenters, 1 being build and 1 in planning...

For context, OVH offers object storage with 3x replication for $.01/GB [1]. [1] https://www.runabove.com/cloud-storage.xml

And the bandwidth is $.01/GB and you don't pay for transactions.

Yev from Backblaze here -> I cannot describe how pleased I am to read this comment. Thank you!

I want a way to be able to use this with ssh rsync scp and so on to preserve legacy backup routines that are now in place. (Including on systems that you will not be writing b2 clients for like old versions of Solaris).

The canonical $$$ (relatively) way to do this is rsync.net: http://rsync.net/pricing.html

Saved me from losing quite a bit of data when a tornado trashed my apartment.

I'm thrilled that we can offer this raw cloud storage for just $0.005/GB/month. Would love to hear from the Hacker News community what you do with storage today & what you might do with B2. Here are my thoughts on our announcement today: https://www.backblaze.com/blog/b2-cloud-storage-provider/ Gleb

> Would love to hear ... what you might do with B2.

B2 finally creates an option for Linux users to use BackBlaze for back-up (at minimum) at work and at home. I look forward to that.

Like I asked below, do you have a citation?

"No one data center serves two availability zones" : http://www.theregister.co.uk/2015/04/16/aws_data_centre_arch...

From your link:

"To solve latency, Amazon built Availability Zones on groups of tightly coupled data centres. Each data centre in a Zone is less than 25 microseconds away from its sibling and packs 102Tbps of networking."

25 microseconds at the speed of light (best case, through a vacuum; through fiber is significantly slower) is ~4.7 miles, and based on the quote, that is the furthest they are apart. If your buildings are within 1-2 miles of each other, they're essentially the same facility.

That is not geographically redundant.

Reading the API, it seems that I need to precalculate a SHA-1 before uploading? This makes it impossible to stream data to b2 from another source, I'll need to store it first then send to b2.

Right now your only option would be to "buffer" packets of say 1 MByte in RAM, calculate the SHA-1, then store them as separate files in Backblaze B2.

We do plan to add file offset access and larger file support very soon, so you would be able to append a 1 MByte chunk to an existing file in Backblaze with a SHA-1 of only the 1 MByte chunk. That should allow you to stream?

All great feedback, by the way. We really want to hear about these shortcomings in our API right away.

Yeah, that would be sufficient.

Sure, it's not geographically redundant, but nobody in this thread claimed it was. DinkyG disputed that your "one datacenter" claim was false, which it appears to be.

Now with B2 we immediately support Linux and provide a client for it out of the box (written in python). Granted, it is only a command line interface so give us a little time to polish it up and add some features.

Another Linux user here who would love to use a command line Python tool to backup my data to Backblaze: with Python I can see how my stuff is encrypted. That's the only reason I'm not using Backblaze right now: closed source client. My only interest in B2 is backing up for a lower cost than the ridiculousness of S3: at $0.022/GB, I might as well buy a 3TB hard drive myself, put it at a friend's and push my data ther…

You are ignoring the Electricity/BW costs spent by your friend which would raise your costs

I use backuplizard for personal data/photos which works out more like cost of a one 2 TB disk per year to me and to me Its easy to pay it instead of owning disks and worry about them breaking,etc
