How Do I Upload Objects Larger Than 5 GB?
Context
OBS Console puts limits on the size and number of files you can upload.
- In regions where batch upload is supported, a maximum of 100 files can be uploaded at a time, with a maximum total size of 5 GB.
- In regions where batch upload is not supported, only one file can be uploaded at a time, with a maximum size of 50 MB.
Therefore, for a single file to be uploaded, its maximum size can be 5 GB in a batch upload or 50 MB in a single upload.
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 OBS Browser+
Files are uploaded using multipart upload on OBS Browser+. With multipart upload, you can upload a single file with the maximum size of 48.8 TB.
OBS Browser allows up to 500 files to be uploaded at a time.
