Biz Storage File Transfer

FAQ

Here, we provide answers to questions from our customers.

FAQ about service
Troubleshooting for Web
Troubleshooting for Client Software
Q01. What is the file size that can be sent at once?

It is possible to send files sized up to 100GB after compression.

However, the maximum is 2GB for the Web version. 

Q02. What kind of encryption is used?

The following encryption methods are used with Biz Storage File Transfer. 

・File encryption: A hybrid system combining a common key cryptosystem and a public key cryptosystem*

*"Camellia" (up to 256kbit), the world's highest standard of encryption technology, is used for the public key. This does not apply to the Web version. 

・Communication pathway encryption: SSL (128 bit)

 

The user can use the "Create key" button in the Biz Storage File Transfer software to automatically create a public key on the Biz Storage File Transfer server and a secret key on the local PC. This makes it possible to obtain the destination's public key to encrypt the file sent using Biz Storage File Transfer processing, and then use the secret key to decrypt the file once it has been received.

Therefore, as it is necessary for the pair of the public key and secret key used for the file sent to match, care is required with regard to the timing of key updates.

Q03. What is the difference with other file sharing services (storage services)?

The mechanisms could be compared to familiar systems where the file sharing service is a "file server" and Biz Storage File Transfer is "e-mail."

Both are the same in that they can be used for large file transfers, but it could be said that the file sharing service is suited for releasing the latest data over the Internet to be used in collaboration shared between several users.

Meanwhile, Biz Storage File Transfer could be considered to be suited to data transfers in the workflow because it is specialized in transfers for delivering files to a certain destination. 

Q04. We would like to use Biz Storage File Transfer for file transfers with clients, but do clients need to install Biz Storage File Transfer as well?

As a rule, Biz Storage File Transfer requires an account ID for both the sending and receiving sides.

* The account ID is like an e-mail address, and is used for authentication and as an address when using Biz Storage File Transfer. 

Q05. How long does it take from applying until the start of service?

This may vary depending on the system created. Please contact us for details. 

Q06. Is it necessary to set up a new Internet access line?

When using Biz Storage File Transfer, there are no particular restrictions on Internet access (or leased line) providers or line speed. We can support the customer's requirements including existing lines. 

Q07. Can a single Biz Storage File Transfer account be used for several PCs?

Technically, it can be used, but take note of the following problems:

(1) If one PC receives a file first, the same file cannot be received from the Biz Storage File Transfer server.

(2) As a secret key can only exist on a single PC, some PCs will be unable to decrypt files if the file sent is encrypted.
