Data Online Migration:Manage migration jobs

Subsequent operations vary with the types of migration jobs. You can manage migration jobs of different types as follows.

Manage full migration and incremental migration jobs

• View the status of a full or incremental migration job
  After you create a migration job, one of the following states is displayed for the job:

  • Migrating. This state indicates that data is being migrated. Wait until the migration job is completed.
  • Create Failed. This state indicates that the migration job failed to be created. You can view the cause of the failure and create a new migration job.
  • Completed. This state indicates that the migration job is completed. You can view the migration report.
  • Failed. This state indicates that the migration job failed. You can view the migration report and migrate the files that failed to be migrated.
• Modify the throttling settings of a migration job
• View a migration report
  1. On the Migration Jobs page, find the migration job and click Manage.
  2. Click Generate Migration Report. After a report is generated, click Export to export the report.
     In a migration report, the following files appear in the File lists section:

     • The file whose name ends with _total_list. This file lists all files that need to be migrated.
     • The file whose name ends with _completed_list. This file lists the files that are migrated.
     • The file whose name ends with _error_list. This file lists the files that failed to be migrated.
  3. At the destination NAS data address, find the generated folder aliyun_mgw_import_report/. The folder includes the three files listed in the migration report. You can download the files and view the detailed list included in each file.
     Each list consists of the following columns:

     • The columns of the file name that ends with _total_list include the source data address, file name, source version ID, and destination version ID. The columns also display whether the job version is latest at source data address and whether the job version is deleted at source data address. The last two columns display the file size (measured in bytes) and time when the file was last modified. The format of a source data address is nas://<the name of a mount point>:/<prefix>/<objectName>, for example, nas://0a28888892-afr82.cn-hangzhou.nas.aliyuncs.com:/myprefix/testfile.txt.
     • The columns of the file name ends with _completed_list include the file name, source version ID, destination version ID. The columns also display whether the job version is latest at source data address and whether the job version is deleted at source data address. The last four columns display the file size (measured in bytes), CRC-64 checksum, time when the migration job was completed, and whether the migration was skipped.
       Note Skip migration: indicates whether the file was skipped during migration. Valid values: 1 and 0. The value 1 indicates that the file was skipped during migration. The value 0 indicates that the file was migrated. The value of this field depends on the value of the File Overwrite Method parameter.
     • The columns of the file name ends with _error_list include the file name, source version ID, destination version ID. The columns also display whether the job version is latest at source data address and whether the job version is deleted at source data address. The last three columns display the time when the migration job started, time when the migration job ended, and error description.
       Note The following four fields apply only when the migration job has multiple versions.

       • Source version ID: the version ID of the file at the source data address.
       • Destination version ID: the version ID of the file at the destination data address.
       • Latest at source data address: indicates whether the current version is the latest version of the file at the source data address. Valid values: true and false.
       • Deleted at source data address: indicates whether the current version is deleted at the source data address. Valid values: true and false.
• Retry a job after a migration failure
