Working with objects

Copying objects

You can use the TOS console to copy files or folders to different locations. This topic explains what to consider and what steps to take.

Prerequisites

Category	Description
Versioning	If you have enabled versioning for your bucket, make sure you toggle off the Show versions switch on the Objects page before copying any objects.
Storage type	Before copying objects from Archive, Cold Archive, or Deep Cold Archive, you must first restore them to a readable state.

Constraints and limitations

Category	Description
Scope	The copy operation in the TOS console copies the following information about objects: content, size, last modified time, creator, version number, user-defined metadata, and storage type.
Redundancy	You can copy objects between single-AZ and multi-AZ buckets within the same region. After an object is copied to a single-AZ or multi-AZ bucket, it inherits the bucket's redundancy type and becomes a single-AZ or multi-AZ object. For more information on multi-AZ, see Multi-AZ redundancy.
Size limit	Through the console, you can only copy objects smaller than 50 GiB. To copy larger objects, use TOS Browser or tosutil.
Usage limits	This topic only covers copying objects within the same region. To copy objects across regions, use cross-region replication instead. For instructions, see Cross-region replication. Copying an object to its original location is not permitted.

Notes

Exercise caution when copying objects between parent and child directories. Objects with the same name at different levels may be overwritten, which could result in data loss.

Steps

In the left navigation pane, click Buckets.

In the top menu bar, select the project of the bucket you want to manage.

On the Buckets page, click the name of the bucket.

On the Objects page:

Select the file or folder you want to copy by checking the box next to it.

Click Copy to at the bottom of the list.

In the Copy To Folder dialog box, select a folder, and then click Copy.

tip

To copy objects to a new folder, click Create Folder in the lower-left corner of the dialog box. Then, enter the folder name, and click the checkmark icon. For folder naming rules, see Creating folders.

If the destination folder contains an object with the same name, you can choose to Overwrite or Skip it. Then, click Copy to finish copying.
