Resuming an Upload

Connectivity problems can interrupt an upload. When you resume an upload, Amazon EC2 automatically starts the upload from where it stopped. The following procedure steps you through determining how much of an upload succeeded and how to resume it.

To resume an upload

Use the task ID with ec2-resume-import to continue the upload. The command uses the HTTP HEAD action to determine where to resume.

ec2-resume-import disk_image -t task_id -o owner -w secret_key

Example

The following example resumes an import instance task.

$ ec2-resume-import Win_2008_R1_EE_64.vmdk -t import-i-ffni8aei -o AKIAIOSFODNN7EXAMPLE -w wJalrXUtnFEMI/K7MDENG/bPxRfiCYEXAMPLEKEY

The following shows the output when the import instance task is complete:

Disk image size: 5070303744 bytes (4.72 GiB)
Disk image format: Stream-optimized VMDK
Converted volume size: 26843545600 bytes (25.00 GiB)
Requested EBS volume size: 26843545600 bytes (25.00 GiB)
