4.1 Workflow
4.1.1 About Workflow
Data check workflow is a complete process composed of components and their dependencies
to complete certain functions. Components are the basic units that constitute a workflow, and
each component only completes a single function. In this document, workflow specifically
refers to data check workflow. It includes the following components:

⚫ Start: the starting point of a workflow.
⚫ End: the end point of a workflow.
⚫ Policy: the execution policy of a workflow, used to automatically trigger the workflow.
⚫ Check: used to collect the relevant information of the backup job to be verified, for the
execution of the data check job.
⚫ Workflow scheduling mode: serial scheduling and parallel scheduling.
⚫ Serial scheduling: multiple components are executed sequentially. The downstream
component will trigger the execution only after the upstream component is executed.
Applicable to sequential dependencies among multiple check components.

Issue 01 (2025-05-30) Copyright © Huawei Cloud Computing 7
Technologies Co., Ltd.

HCS Backup Recovery (HBR)
User Guide for Backup Data Integrity Check 4 Workflow Management

⚫ Parallel scheduling: multiple components are executed in parallel. If there is a
convergence point, the convergence point can be executed after all components are
executed. Applicable to multiple check components without dependencies.

The workflow management function is supported in HBR Portal only.
4.1.2 Workflow Orchestration Rules
A workflow includes four types of components: start, policy, check and end, among which the
start, check, and end components are required, and the policy component is optional.
There are certain restrictions on the upstream and downstream, and the number of each
component, as illustrated in the following table:

Component Upstream Downstream Component Quantity Limit
Name Component
Start - Policy, Check Only one
Policy Start Check Up to one
Check Start, Policy, Check, End At least one
Check
End Check - Only one

Step 4 Saving/Publishing/Returning the Workflow
After configuring the components, click Save to save the workflow. Click Publish to save
and publish the workflow. Click Back to discard the canvas content and return to the
Workflow page.

If a workflow contains multiple Check components, the Check components cannot be associated with
the same backup job.
If a workflow contains a Check component and a Policy component, and the Check component is
associated with a backup job of SAP HANA application, the workflow execution will take too long
when the Policy component is associated with policies with Check Range of All points in time/Log
backup points in time, because the generation of SAP HANA log backup points in time is
uncontrollable and enormous. It is recommended that the Policy component is associated with policies
of other check range.

4.5 Starting a Workflow
4.5.1 About Starting a Workflow
A workflow can be started manually or by policy:
By manual: Click Start by a tenant/operator in the Workflow interface.
By policy: It refers to the Policy component configured in the workflow and the workflow
will automatically start based on the check policy configured in the Policy component.
To start a workflow by policy, mind the following:

⚫ The workflow must be associated with a valid check policy, that is, the check policy
status is enabled, and the check policy start time must be greater than the HBR console
system time.
⚫ Assume that the Time Range for Check of the check policy associated by the workflow
is Specified and the current time is not within the specified time range, the workflow
will automatically execute within the range when HBR console system time reaches the
check policy start time.
⚫ Assume that the Range of the check policy associated by the workflow is XX backup
points in time (such as differential backup points in time) and the job configured in the
Check component does not have this backup type, the workflow execution will not be
triggered by the check policy.
⚫ Assume that the Check Cycle of the check policy associated by the workflow is Once,
the status of the policy in the Policy component of the workflow will automatically
change to Disabled after the check policy is triggered.
⚫ If the status of a workflow is Unpublished, the check policy will not trigger the
workflow execution.

5.1 Failed to Add a Workflow for Backup Data Integrity Check of SAP HANA Database

5.1 Failed to Add a Workflow for Backup Data Integrity
Check of SAP HANA Database
When adding a workflow, it prompts "Failed to associate the policy to the workflow. Cause:
SAP HANA database only allows associating to policies with the check range of all points in
time. (Error code: 400888059)”.
Close the above tips, save/publish the workflow again, and it prompts “Failed to create the
workflow. Cause: a workflow with the same name exists. (Error code: 400567152)”.
Cause:
The Check component is associated with the backup job of SAP HANA database but the
Policy component contains policies with “Range” of not “All points in time”, so the error
“Failed to associate the policy to the workflow...” occurs. At this point, the workflow is
successfully saved, but the policy associated with the workflow is not saved. Therefore, it will
prompt “Failed to create the workflow...”.
Solution:
Click Back to return to the workflow list. Edit the workflow, modify the Policy component,
add a policy with the "Range" as "All points in time", and click Save/Publish again.
