UninstallBackupClients - Cloud Backup - Alibaba Cloud Documentation Center

Uninstalls a Cloud Backup client from one or more Elastic Compute Service (ECS) instance.

Operation description

This operation creates an asynchronous job at the backend and calls Cloud Assistant to uninstall a backup client from an ECS instance.
You can call the DescribeTask operation to query the execution result of an asynchronous job.
The timeout period of an asynchronous job is 15 minutes. We recommend that you call the DescribeTask operation to run the first query 30 seconds after you call the UninstallBackupClients operation to uninstall backup clients. Then, run the next queries at an interval of 30 seconds.
