The following configuration and tuning changes are recommended.
Description | Detail |
S3 repository chunk size | Big files can be broken down into chunks during snapshotting if needed. You can specify the chunk size in bytes or by using size value notation, that is: 1gb, 10mb, 5kb. The default is 1gb.
Dell recommends using the default setting of 1gb. |
S3 repository buffer size | The Minimum threshold below which the chunk is uploaded using a single request. Beyond this threshold, the S3 repository will use Multipart upload to split the chunk into several parts, each of buffer_size length, and to upload each part in its own request.
Dell recommends using the minimum default setting between 100mb and 5% of the heap size. |
