This topic provides answers to some frequently asked questions (FAQ) about the billing of Data Transport.
How do I choose between the pay-by-data-volume and pay-by-lease-days billing methods?
You can select an appropriate billing method based on the read throughput of the origin server.
If the read throughput of the origin server is stable and data migration is estimated to be complete in one month, you can select the pay-by-data-volume billing method.
If the read throughput of the origin server is unstable or other uncontrollable factors exist, we recommend that you select the pay-by-lease-days billing method.
We recommend that you select the pay-by-lease-days billing method because it has a finer billing granularity. Before you place an order, carefully evaluate the volume of data to be migrated and the use days of the device. After you place an order, you are not allowed to change the billing method. You cannot request a refund even if you return the device in advance. For more information about billing methods and fees, see Billing.
What do I do if the lease term is insufficient?
We recommend that you carefully evaluate the number of days required for data migration before you place an order. If more days are required after the end of the lease term, you can place another order. If you do not return the device within seven days after the end of the lease term, the device is deemed lost and you must compensate for the lost device. For more information, see What do I do if I lose or damage the device?
What do I do if I lose or damage the device?

Do I need to pay for logistics?
If you use a Data Transport device in the Chinese mainland, you do not need to pay for logistics in most regions. The order amount does not include the fees for the mailing and retrieval of the device in Hainan, Qinghai, Inner Mongolia, Xinjiang, and Xizang.
If you use a Data Transport device outside the Chinese mainland, you must arrange logistics by yourself and pay for it.
