This article mainly introduces the method of running the same mirror environment in ECS instances in different regions, which can be used for reference by friends who need it. I hope you will learn a lot after reading this article. Next, let the editor take you to learn about it.

Copy Mirror

Replicated images are suitable for cross-region deployment of applications. You can run the same image environment in ECS instances in different regions. You can copy a custom image from one region to any other Ali cloud region, but the task completion time depends on the network transmission speed and the number of concurrent tasks queued.

Matters needing attention

When replicating a mirror, a corresponding snapshot is generated in the destination region, and then a custom image is generated based on the snapshot in the destination region. Therefore, please pay attention to the possible costs:

Traffic charges for data transmission between different regions. At present, there is no charge for this part of the traffic, and the specific charging time shall be subject to the announcement of Aliyun.

Copied snapshots consume snapshot capacity.

Since March 28th, ECS snapshots have been commercialized and included in the billing service. For more information, please see Snapshot Billing. For more information about snapshot charges, see Snapshot Commercial FAQ.

After copying the image, you will get a custom image with the same configuration in another region. However, the relevant role authorization and service authorization information will be lost, and the instance customization data that was originally set will not be included.

Operation steps

The steps to replicate a mirror on the ECS Management console are as follows:

Log in to the ECS Management console.

Select the region.

In the left navigation bar, select Snapshot and Mirror > Mirror.

Select the mirror to be replicated, and the mirror type must be a custom mirror. In the Operation column, click copy Mirror.

Description

If the custom image you want to copy is greater than 200 GiB, you need to submit a ticket for processing. When you click the copy image, the system guides you to submit a work order.

In the copy Image dialog box, you can see the ID of the selected custom image. You need to complete the following settings:

Select the destination region.

Enter the custom image name and description displayed by the image in the target region.

Click OK.

Switch to the destination region and check the replication progress of the custom image. When the progress is displayed as 100%, the task is completed.

Description

If the progress is less than 100% and the status is in the process of creation, you can click cancel to copy at any time. After canceling the task, the custom image is no longer displayed in the mirror list in the target region.

You can also use ECS API CopyImage and CancelCopyImage to complete the replication mirror task.

Next step

When the state of the mirror becomes available, you can use the replicated mirror to create an instance or replace the system disk (non-public mirror).

You can also view snapshot information copied from the source region in the destination region of.
