How Do I Upload Objects Larger Than 5 GB?

Context

Methods

• 5 GB < Object ≤ 48.8 TB

  If an object is larger than 5 GB, you can use OBS Browser+ or obsutil to upload it. Or you can use the OBS SDKs or API to upload the object (up to 48.8 TB) with a multipart upload.

  • Using obsutil

    With multipart upload, you can upload a single file with the maximum size of 48.8 TB. There is no limit on the number of files that can be uploaded at a time.

    For details about using obsutil to upload objects, see section "Uploading an Object" in the Object Storage Service Tool Guide (obsutil).

  • Using OBS SDKs

    OBS SDK supports uploading a large object with a multipart upload. A multipart upload consists of initiating a multipart upload, uploading parts one by one or concurrently, and assembling parts.

    2. Uploading parts (see section "Uploading Parts" in the Object Storage Service API Reference)
    3. Completing a multipart upload (see section "Completing a Multipart Upload" in the Object Storage Service API Reference)
