Batch Operation

Terakhir diperbarui:2022-11-07 15:30:21


    The COS batch operation feature allows you to perform large-scale batch operations on objects in a bucket. With this feature, you can now perform the following operations in batches:

    • Copying objects
    • Restoring archived objects

    You can generate an inventory file for the objects on which to perform a batch operation by using either COS inventory (you need to first enable the inventory feature as instructed in Setting Inventory), or the CSV format you specify. COS will then perform this batch operation based on the inventory file. For more information on batch operations, see Batch Operation Overview.


    1. Log in to the COS console.
    2. On the left sidebar, click Batch Operation to enter the batch operation management page.
    3. Click Create Job to create a batch operation job.

    The configuration items are as described below:

    • Job Region: Select a region for the job. It must be the same as the bucket region where the objects in your inventory file reside; otherwise, the job will fail.

      Currently, COS batch operation is only available in public cloud regions in Chinese mainland and Silicon Valley region.

    • Inventory Format: Select a format for the objects to be inventoried from the following two options:
      Inventory Format Field Configuration Description
      COS inventory report - You can use an inventory report generated by COS as the inventory file or create your own inventory file in CSV format.
      CSV Bucket Bucket name
      Key Name of the object in a bucket. The object name encoded in URL format must be decoded and then can be used properly.
      VersionId Object version ID. If versioning is enabled for a bucket, COS will assign a version ID to each object added to the bucket. If you don't want to inventory the latest version of an object, you can specify a particular version ID.
    • Inventory Bucket: Select the bucket where the inventory file is stored.
    • Inventory File Path: Specify the path of COS inventory report or CSV file in the format: directory/manifest.json or directory/manifest.csv, respectively. For example, if you have an inventory file stored in the examplebucket-1250000000 root directory, the inventory path will be manifest.json.
