Hey guys,

I'm just wondering if there is a way to estimate on how much does it cost to purchase and maintain 1pb (Peta Byte) for cloud backup?

I have just basic knowledge on servers, so please be explainatory.

It's for education purpose only.

Thanks in advance.

The cost of 1PB of storage is pretty hard to measure, because there are many factors. The biggest hard drives available provide 12TB of storage. So that mean you need 83 disks to have 1PB.

And then, you have to use a storage solution to be able to use them as a single disk. For this usage, a simple RAID isn't possible (or not a good idea), you have to use a distributed storage solution like Ceph, and that also mean, you will need more than 1PB storage to have some redundancy and not loose all your data in case of fail.

And the last point will be the amount of server needed, because a single server may not be enough (for physical reason, 83 disk require a lot of space) and for access reasons (how many network cards do you need to use to handle the traffic on 1PB of storage).

So the cost will probably be very high, with several dedicated servers and a lot of additional disks.

Biggest storage server available on OVH provide 72TB or storage for $500/mo.

So that mean 500$ x 13 = 6500$ for 1PB storage without any redundancy.

I wonder for what will you used it for, or for how will you be using it. But 1 petabyte storage will cost you a lot. Just imagine buying 1 terabyte storage and multiply it to the extent you can reach the amount of petabyte by using one terabyte.

The starting point to this surely will be, please define your use of the term 'cloud'... Then, what exactly do you want to achieve and why?

Your question appears to suggest you will buy the hardware. In such case, a simple look at any number of suppliers for large scale networked storage will tell you the hardware cost starting point.

Your intended use will then tell you if extra hardware is needed (InfiniBand, drive buffers / caches for prefetch and read write, a hybrid system, etc), and then if you can even fill that much space... exactly how you will be reading and writing the data, and any performance and bandwidth allocation...

The more background you supply, the more meaningful a response can be given.

If you are just shooting from the hip, then the only answer to how much? Will be a lot / too much, depending on your budget...

The cost of 1PB of storage is pretty hard to measure, because there are many factors. The biggest hard drives available provide 12TB of storage. So that mean you need 83 disks to have 1PB.
SSD drives are already 16TB+ for the largest production drives (Samsung), and in 2016 Seagate announced a 60TB that was to come out in 2017, but seems delayed... Putting 24 of these Seagates into a single chassis would give you around 1.44 PB as a JBOD.... and if there is no budget cap, and no rush, that may be the best option for the mother of all arrays....

I will get multiple servers with 2 TB hard disk each, then will create my own SAN. I will need 500 servers to create 1 PB SAN, so each server cost $100, we get:

$100 X 500 = $50,000

It will cost you atleast $50,000 per month to get 1 PB storage.

Ofcourse there are many shortcuts like buying own hardware and than put it on rack which will be cheaper.

I didn't think its requiring big budget like that or which type of sites will need this plan? :)

So the cost will probably be very high, with several dedicated servers and a lot of additional disks.

So that mean 500$ x 13 = 6500$ for 1PB storage without any redundancy.
Thanks for clarifying me these factors, I am wondering I can use a storage server to host my websites in the case it needs to store a large amount of data?

I wonder for what will you used it for, or for how will you be using it. But 1 petabyte storage will cost you a lot. Just imagine buying 1 terabyte storage and multiply it to the extent you can reach the amount of petabyte by using one terabyte.
Use for? I am thinking about building a video sharing site which allows users to upload their own videos to hosting.

That's different then "cloud backup" which is what you initially wrote. Prices for backup space are not the same as hosting space. Hosting will run a bit more.

That's not correct. If you lease a dedicated server from a reasonable web host, you should be able to a much better deal than that. My firm would provide such for a lot less in fact. :)
