Currently, files that users delete manually by mistake cannot be restored. However, you can enable versioning on your bucket to help recover future data lost due to accidental deletion or application failure. It is because versioning allows you to upload and store multiple versions of an object with the same name in your bucket, so that you can extract, delete, or restore a specified version of the object. For more information, see Setting Versioning.
An incomplete multipart upload is generated when you suspend or cancel an object upload. COS allows you to upload a large file greater than 5 GB in multiple file parts. During a multipart upload job, uploaded parts will be stored as an incomplete multipart upload and cannot be downloaded if you don’t call the Abort Multipart Upload or Complete Multipart Upload API.
Like objects, incomplete multipart uploads consume your storage capacity, and incur storage usage fees.
You can delete an incomplete multipart upload directly by using the COS console. For directions, see Deleting Incomplete Multipart Upload. Alternatively, you can regularly clear incomplete multipart uploads by configuring a lifecycle.
No, it won’t. It just deletes the unsuccessful uploads.
COS supports custom headers. For more information, see Custom Headers.
You can realize this by using COS with SCF. For more information, see Acquire Image on COS and Create a Thumbnail.
COS allows you to view the number and size of objects in the current folder. For more information, see Viewing Folder Details.
Once you enable Versioning on your bucket, you can store multiple versions of an object in the bucket, and extract, delete or recover a specified version of the object. For detailed directions, see Setting Versioning.
To do this, you can enable inventory, and check your generated inventory report. For more information, please see Enabling Inventory.
