Such a large amount of data, limited to cost considerations or other restrictions, cannot temporarily/permanently lease high-bandwidth upstream and downstream electronic lines, leaving only the physical transmission of traditional storage devices.

University computer network course teacher, played a rough analogy, probably means the largest bandwidth network, is a large capacity to search for a container transport ship. Although this network flaw is the delay is huge, but true, the bandwidth superiority is incomparable.

Specific to the measures, the comprehensive consideration of price-performance, without prejudice to:

1, large-capacity mobile hard disk 3 blocks, storage database. The mobile hard disk itself uses the file system Layer certificate encryption (Ntfs,linux EXT,OSX of Windows is supported by HFS, which itself indicates that this requirement is common), or is protected with the password of the compression tool. Very worrying about data security, you can also work with file signatures to further verify data integrity.

2, the key file or password in the organization authorization, the identification of the recipient's identity/organization information, using the network of various encryption transmission technology (VPN,HTTPS, etc.), to the receiving party there.

3, each block of mobile hard disk, or go to different courier service providers, or batches of times, or both, with Express.

4, after receiving the mobile hard disk, use the key or password to take out the file, the file signed, and then verify the signature. After all passes, even if the transmission is complete.
