Overview of Data Transfer Service
Learn about how you can use the Overview of the Data Transfer service to migrate your data to Oracle Cloud Infrastructure using either a user-supplied storage device, or an Oracle-supplied transfer appliance.
Oracle offers offline data transfer solutions that let you migrate data to Oracle Cloud Infrastructure. You can also export data currently residing in Oracle Cloud Infrastructure to your data center offline. Moving data over the public internet is not always feasible because of high network costs, unreliable network connectivity, long transfer times, and security concerns. Our transfer solutions address these pain points, are easy to use, and provide faster data upload compared to over-the-wire data transfer.
To simplify this Data Transfer documentation, we generically refer to Object Storage to mean that you can transfer data into a bucket in either the Object Storage tier or Archive Storage tier.
Watch a video introduction to the Data Transfer service.
- DISK-BASED DATA TRANSFER
- You send your data as files on encrypted USB 2.0/3.0 disk to an Oracle transfer site. Operators at the Oracle transfer site upload the files into your designated Object Storage bucket in your tenancy.
- This transfer solution requires you to source and purchase the disk used to transfer data to Oracle Cloud Infrastructure. The disk is shipped back to you after the data is successfully uploaded.
- See Data Import - Disk for details.Note
Disk-based data transfer is not supported for regions with FedRAMP authorization and regions with US Federal Cloud with DISA Impact Level 5 authorization.
- APPLIANCE-BASED DATA TRANSFER
- You send your data as files on secure, high-capacity, Oracle-supplied storage appliances to an Oracle transfer site. Operators at the Oracle transfer site upload the data into your designated Object Storage bucket in your tenancy.
- This solution supports data transfer when you are migrating a large volume of data and when using a transfer disk is not a practical alternative. You do not need to write any code or purchase any hardware. Oracle supplies the transfer appliance and software required to manage the transfer.
- See Data Import - Appliance for details.
- APPLIANCE-BASED DATA EXPORT
- You export your data from your Oracle Cloud Infrastructure Object Storage bucket to your data center using an Oracle-provided appliance.
- This solution is useful if you have media content or processed datasets you need to share with a customer or business partner.
- See Appliance Data Export for details.
Limits on Data Transfer Service Resources
When you sign up for Oracle Cloud Infrastructure, a set of service limits is configured for your tenancy. The service limit is the quota or allowance set on a resource. Verify that your service limits are set appropriately before you begin the data transfer process.
For a list of applicable limits and instructions for requesting a limit increase, see Service Limits. To set compartment-specific limits on a resource or resource family, administrators can use compartment quotas.
Apply tags to your resources to help organize them according to your business needs. You can apply tags at the time you create a resource, or you can update the resource later with the wanted tags. For general information about applying tags, see Resource Tags.
Use Monitoring to query metrics and manage alarms. Metrics and alarms help monitor the health, capacity, and performance of your cloud resources.
Automation for Objects Using the Events Service
The Events service generates automation based on the state changes of resources throughout your tenancy. For more information, see Overview of Events.
Events for objects are handled differently than other resources. Objects do not emit events by default. Use the Console, CLI, or API to enable a bucket to emit events for object state changes. You can enable events for object state changes during or after bucket creation.
You can set up different types of notifications to alert you when any change happens to during your data transfer. See Notifications.
To fully utilize notifications, setup events that trigger the notifications. See Overview of Events for more information.
You can also set up notifications for appliance-based import and export jobs using a CLI command. The notifications run from the CLI provides a more convenient process than using the Notifications and Events services. Instructions for setting these CLI-based notifications are in the Preparation topics for appliance-based import and export.
Data Transfer uses the following encryption methods:
Data at rest is encrypted with AES-256 encryption.
Node-to-node communication is encrypted with GCM-AES-128.
Console and API are using TLS and will default to AES-256.
You can use Oracle Cloud Infrastructure FastConnect with your Data Transfer jobs. FastConnect provides an easy way to create a dedicated, private connection between your data center and Oracle Cloud Infrastructure. FastConnect provides higher-bandwidth options, and a more reliable and consistent networking experience compared to internet-based connections.
See FastConnect for more information.
You can use Oracle Cloud Infrastructure Site-to-Site VPN with your Data Transfer jobs. Site-to-Site VPN provides an IPSec connection between your on-premises network your virtual cloud network (VPN).
See Site-to-Site VPN for more information.
Inputting Text into Data Transfer
You must use only ASCII text for all inputs to Data Transfer. This requirement applies to the browser-based Console and CLIs.
