This section describes how to upload local files to OBS over the Internet. These files can be texts, images, videos, or any other type of files.

Limitations and Constraints

OBS Console supports uploading files in a batch. A maximum of 100 files can be uploaded in a batch with the total size of no more than 5 GB. If the size of a file exceeds 5 GB, use the OBS API for multipart upload.
If versioning is disabled and the name of a newly uploaded file is the same as that of a file in the bucket, the newly uploaded file automatically overwrites the existing file and does not retain the ACL information of the existing file. If the name of the newly uploaded folder is the same as that of a folder in the bucket, the two folders will be merged, and files in the new folder will overwrite namesake files in the old folder.
If versioning is enabled and the name of a newly uploaded file is the same as that of a file in the bucket, a new version is added to the existing file. For details about versioning, see Versioning Overview.

Prerequisites

At least one bucket has been created.
If you want to classify files, you can create folders and upload files to different folders. For details about how to create a folder, see Creating a Folder

Procedure

In the bucket list, click the bucket to be operated. The Overview page of the bucket is displayed.
In the navigation pane, click Objects.
Go to the folder to which objects are uploaded. Click Upload Object. The Upload Object dialog box is displayed.

NOTE:

If the files that you want to upload to OBS are stored in Microsoft OneDrive, it is recommended that the names of these files contain a maximum of 32 characters to ensure compatibility.
Select a storage class. If no storage class is selected, the file will inherit the storage class of the bucket.
Add a file or folder to be uploaded by dragging it to the Upload Object area.

You can also click add file in the Upload Object area to select files.
Optional: Select KMS encryption to encrypt the uploaded file. For details, see Uploading a File with Server-Side Encryption.

NOTE:

If the default encryption is enabled for a bucket, uploaded objects are automatically encrypted.
Click Upload.

Related Operations

You can specify its storage class when uploading an object or change its storage class after the object is uploaded. The procedure is as follows:

In the bucket list, click the bucket to be operated. The Overview page of the bucket is displayed.
In the navigation pane, click Objects.
Select the target object and choose More > Change Storage Class on the right.
Select the desired storage class and click OK.

NOTE:

Objects can be changed from Standard to Warm or Cold storage class, or from Warm to Standard or Cold storage class, but objects in Cold storage class must be restored before being changed to Standard or Warm storage class. Changing from Warm or Cold to other storage classes incurs restoration fees. Select an appropriate change option based on your actual needs.
When the storage class is changed to Cold, the object restoration status changes to Unrestored.
You can also configure a lifecycle rule to change the storage class of an object. For details, see Configuring a Lifecycle Rule.

Follow-up Procedure

You can click Copy Path on the right of an object to copy the path of the object.

You can share the path with other users. Then they open the bucket where the object is stored and enter the path in the search box to find the object.
