Need more storage? How does 220TB sound?

As someone who consults on Big Data, I'd disagree somewhat. The idea behind Big Data is that you do not need backups, since you are A) (site-)redundant and B) write protected at the fact-layer.

Instead, you would continue to throw more quasi-commodity nodes at the problem.
Unless of course you have to have tape backups for legacy oversight purposes.
 
Tapes is the only long term backup. Its also offline and you can place it in a fire resistance safe.

Online backup works for some things. But its a devil in disguise. Any hacker or employee going crazy can wipe it all just to mention one of the flaws.

....which is why I just don't dig on the whole 'cloud' storage thing and never will.
 
Correct. I always use cloud storage as another backup. I also believe that cloud servers have backups, or at least they should.

Do they list prices for the tapes and equipment?

Cloud dont have backup. Its based on storing data on 3 HDs in at least 2 locations. Using blockbased differences as well for extra restore selection.

But there is essentially no backup as such. But what had you expected with that cost structure.

Thats also why its just a matter of time before any bigger cloud service provider will lose large amount of data on the floor.

Plus it leaves the awful question as well, what happens if your cloud provider goes bankrupt.

Even Google, Microsoft and Amazon loses cloud data.

We use Microsoft Azure and the default is to have replication to another data center. They have triple redundancy (2 drives can fail and you don't lose data) locally and then replicate to another data center with same redundancy.

Amazon had told us they also have very similar system but you had to turn it on.
 
Drive redundancy is great to protect against sudden hardware failures, but it does little in the face of malicious attacks such as from hackers, disgruntled employees, etc. That's where you need cold storage, which is where stuff like a 220Tb tape comes in handy. They can do a monthly backup of the entire data center on just one cartridge, just in case such an attack.
