Billing

SMS is free, but you are billed at standard rates for EVS disks, EVS disk snapshots, and data transfer during the migration process.

  • EVS disks

    SMS creates and attaches a 40-GB EVS disk to each target server temporarily during the migration. These EVS disks are billed on a pay-per-use basis. After the migration is complete, these EVS disks will be released. Do not delete these EVS disks during the migration or change their billing modes to yearly/monthly, or the migration will fail.

    For pricing details about EVS, see EVS Pricing Details.

  • EVS disk snapshots

    SMS creates snapshots for service cutover, data synchronization, and cloning target servers. For details about these snapshots for of target servers, see What Are the Snapshots of a Target Server Used for?

    Legacy snapshots are free. You can use them free of charge. For the billing information about standard snapshots, see Billing for EVS Snapshots.

  • Data traffic

    Traffic is generated during the migration and is billed as follows:

    • If the source public IP address is billed by bandwidth and you use the fixed bandwidth for migration over the Internet, the traffic you used will not be billed.
    • If the source public IP address is billed by traffic and you migrate data over the Internet, the price is calculated by multiplying the unit price of traffic by the amount of data migrated. For details about the unit price of traffic, contact the provider of the source public IP address. The amount of data migrated is the actual usage of disks on source servers.
    • If you use Direct Connect or Virtual Private Network (VPN) for migration, the cost depends on the price of your Direct Connect or VPN connections.

      The preceding fees are for reference only. The actual fees may vary.
