The batch operation feature of COS allows you to manipulate objects in a bucket in batches. Currently, you can perform the following batch operations:
- Replicating objects
You can put the needed objects in an inventory file, which can come from the inventory report generated by the inventory feature (you need to enable the inventory feature first) or be created in the specified format on your own. The batch operation feature can operate on the objects in batches based on this inventory file. For more information, please see Batch Operation Overview.
