FAQs

Updated at:2025-10-21

How many trails can be enabled under one account?

At present, only one trail can be enabled per account.

Can cloud trail be stored in a BOS bucket?

Yes, a trail set can be created to store cloud trails in BOS for long-term retention.

Note: Currently, it only supports storage in the BOS bj Region.

What is the maximum time range of Cloud Trail records queried?

Cloud Trail queries are available for up to 180 days by default.

To extend the queryable period for cloud trails, you can create a trail set that delivers trails to a specified BOS bucket, fulfilling longer-term auditing needs.

Which kinds of information are recorded in the operation event list?

The event list records sensitive operations within the cloud account, such as the creation, configuration, and deletion of cloud service resources. However, it does not log event list queries. For more details, refer to: Product Description -> Supported Services.

Can information in the cloud trail list be deleted?

No. According to standards issued by SAC/TC and international information and data security authorities, audit logs must remain objective, comprehensive, and accurate. As a result, user behaviors and generated records cannot be deleted or modified.

Which regions are supported for cloud trail?

Currently, records are supported across all regions.
