This topic describes the advanced features that are available only after you add IP addresses to a whitelist of Data Online Migration.

The following table describes the advanced features.
Feature Description
Migrate data across regions outside mainland China You can submit a ticket to ensure data compliance and configure a whitelist.

To ensure data compliance, you must provide information such as the ID of your Alibaba Cloud account, source region, source OSS bucket name, destination region, and destination OSS bucket name. If you migrate data of a NAS file system, you must also provide the ID of that file system. Make sure that your data complies with the applicable laws and regulations in the destination region. Alibaba Cloud shall not be liable for any consequences arising from breach of such laws or regulations.

Raise the limit of migration jobs Each Alibaba Cloud account can have a maximum of 10 migration jobs. If the limit is reached, you cannot create more migration jobs. You can submit a ticket to raise the limit of migration jobs and configure a whitelist.
Raise the limit of migration job retries If a migration job fails, you can retry up to three times. You can submit a ticket to raise the limit of retries and configure a whitelist.
Filter specified directories You can filter specified directories by using the following two methods:
  • Exclude specified directories: If you do not need to migrate some directories in the Prefix directory, specify the names of the directories.

    For example, if you want to migrate all the directories in the root_dir/ directory except root_dir/bad_sub1 / and root_dir/bad_sub2, you can select this method and specify bad_sub1/ and bad_sub2/.

  • Include specified directories: If you only need to migrate some directories in the Prefix/ directory, specify the names of the directories.

    For example, if you only need to migrate root_dir/good_sub1/ and root_dir/good_sub2/ in the root_dir/ directory. Then, you can choose the include mode and add good_sub1/ and good_sub2/.

After you configure a whitelist, this feature is available in the Create Job dialog box when you create a migration job. Submit a ticket to filter specified directories.
Raise the limit of incremental migration jobs By default, you can create a maximum of 30 incremental migration jobs. You can submit a ticket to raise the limit of incremental migration jobs.
Note Alibaba Cloud does not guarantee the timeliness of data migration if you need to migrate large amounts of data.
