Upload Part

 

Multipart Uploads are a way of uploading objects that are too large to upload in a single action.

Note:

Spectra Logic recommends that you use Spectra S3 requests to create a PUT job, then upload each object piece in the PUT job, rather than using Multipart Upload (see Processing a Bulk PUT Job). Using a bulk PUT job achieves better scalability and performance. Note that a maximum upload size can be specified on a PUT job if smaller transfer sizes are required.

The general process for Multipart Uploads is as follows:

1.	Initiate the multipart upload; see Initiate Multipart Upload for details.

2.	Upload all parts; see Upload Part for details. Note the PartNumber and ETag for each part.

3.	Complete the MultiPart Upload; see Complete Multipart Upload for details. This request reassembles the object parts into one object. You must provide the PartNumber and ETag for each part.
