How to send a 500GB database to customers?

Listen to me, under the current internet conditions, SF Express on a hard disk is the fastest.

The database of 500G is not small. Such a large database must ensure data security, so it is definitely not possible for you to transfer it on Baidu network disk or other online cloud storage service providers. The best way is to make a copy on the hard disk. If it is an express delivery, the hard disk may be damaged or even lost. So you'd better make a copy of the hard disk and bring it to each other yourself.

The best way is to buy a 5 12G USB flash drive, open bitlocker to go, then mail it to the customer, and then mail the bitlocker password through a secure channel. In this way, the account manager will be very happy to send a large-capacity USB flash drive in disguise, and it can also encrypt the mailing materials, which is very safe!

There used to be a joke that sending an email means saving the file on a floppy disk and then sending it to the other party. In fact, when transmitting big data, direct mail carrier is much faster and more reliable than network transmission.

The fastest and most reliable way is to express the hard disk directly and let the customer service use it directly. If you use the network to transmit the preferred object storage, Tencent Cloud, Alibaba Cloud, Baidu Cloud and Huawei Cloud can all do it, so that you can directly send links to customers to download, without any members, and the download speed is unlimited, and you can run at full bandwidth. For 500G files, you need to pay the external network downlink traffic fee for 250 objects storage. That is to say, no matter what method you use, it takes at least 12 hours for you to upload 500G on the network (in the case of your broadband 100Mbps uplink), and it takes about two hours for the other party to download 500Mbps downlink at full speed. SF Express 12 hours [covering your face] arrived in the hands of customers, so it is still the most reliable and fastest express. Finally, if you upload an important file like a database,

Send a database with a capacity of 500G to the customer, please refer to my suggestion:

1. If it is in the same city or very close, you can choose to deliver the database hard disk to the customer in person, which can ensure the data security and the customer can receive it intact.

2, the distance is far, you can choose express delivery, pack the hard disk of the database, send a good express delivery, such as SF Express, remember to insure the price. Although the data is priceless, it must be guaranteed.

3. If you don't send or don't send the hard disk, you can choose to upload the database file to the object storage of cloud service providers at home and abroad, so that customers can download it, just to eat bandwidth. If you download it, you'd better use Thunder.

4. Upload the database file to Baidu Cloud Disk, and then let customers download it. However, Baidu cloud disk is a bit bad, that is, it will be slow if you don't open a member. If you want to use it, you must open a member.

Finally, data is priceless. Choose the best method for both parties. I hope my answer can help you!

Haven't you learned the speed comparison calculation between a truck full of data and a network at high speed?

If it is a backup of the database, it can be compressed. Generally, 500GB can be compressed to about 10g, and the network disk can be copied away. If it is a binary video file, it is recommended to copy and mail it by hard disk. Network disk is ok, but the cycle is too long.

1. If the customer has his own server and is in the public network, and your server can also be accessed in the public network, you can grant the customer permission. If it is a linux environment, copy directly through scp. Windows environment can also be shared with files. For example,100M bandwidth can reach 12.5m/s, and 1 1 hour can copy about 500g. Replication time is related to bandwidth.

2. If you have a public network environment, establish an ftp directly. If you don't buy Alibaba Cloud, buy a 500g+ hard disk (it seems that 500g is actually available without 500g) and set up an ftp for them to download.

3. Divide and compress the files according to the size of 2g or 1g, and then send them to each other one by one through QQ.

It is best to compress database files, which are all data and have a high compression rate.

Several or two encrypted hard disks, each containing 50% encrypted compressed packets, and then sent to customers in two batches, decrypted with the agreement and certificate negotiated in the sandbox before ... Although it is not completely foolproof, it is at least relatively safe.
