String/Expression/Suggestion

N/A

Specify the S3 bucket name, from where an S3 object is to be downloaded.

Bucket names are unique globally and can be accessed without the region name in most cases. If you cannot access a bucket name without its region name, you can specify the region information with the following syntax:

<S3_bucket_name>@<region_name>

Note: If you enter an incorrect region name, but the bucket name is valid, the AWS S3 service might successfully access the bucket without errors.

• You can access an S3 bucket in an S3 Virtual Private Cloud (VPC) endpoint by specifying the bucket name with the following syntax:

  • <S3_bucket_name>@<VPC_S3_endpoint>

• You can access an S3 Express One Zone bucket with the following syntax:

  • <bucket-name>--<region>-<available-zone>--x-s3

• S3 Express One Zone does not support the following bucket name pattern of :

  • <bucket>@<region_info>.

• S3 Express One Zone does not support VPC.

Multipart Size (MB)

Default Value: 10
Example: 10

Integer/Expression

Specify the multipart size in MB:

• The minimum multipart size is 5 MB.

• The maximum multipart size is 5 GB.

• The maximum number of parts in an S3 object is 10,000, and the maximum size of an S3 object is 5 TB.

• To upload S3 objects that are more than 100 GB, you must increase the Multipart Size to at least the possible S3 object size divided by 10,000.

• The larger the Multipart Size is, the larger the memory size that the Snap uses. For example, if the Multipart Size is 10 MB and the Thread Pool Size is 10, the memory size the Snap uses is 100 MB.
