How do I backup a SAP CAL instance hosted on GCP?

[eric_ruider]

Hello,

when I click the backup option in our SAP CAL instance, the backup will always fail. I already did some research and apparently the storage size in GCP needs to be enlarged manually.

My question is now, which storage I need to enlarge. Is it the VM that hosts the HANA database? And if so, which volume/disk is it? Would be great if someone could provide a quick tutorial.

Thanks in advance

Dear Customer,

For each failed operation SAP Cloud Appliance Library, provides an error message description. You could check it by clicking on the Show Error button. In your case, according our log files, it is missing permitions 'compute.images.create'. Please check our FAQ page -> What are the roles required for the service account to grant permissions to SAP Cloud Appliance Library?.

Best regards,

Tsvetinka

I am sorry, but I could neither find any error message nor any log file on the SAP CAL administration site. Could you please provide any information on how to access those log files?

The service account on GCP already has all required permissions stated by the linked FAQ so I can rule out this error cause.

Dear Customer,

You have successful operations, executed against your appliance, after the failed back up creation. This is the reason for the missing "Show Error" button. If you would like, you could initiate again e new back up creation and to check the error message after that. In order to be able to create back up successfully, the missing required permission (in your case) is "compute.images.setLabels" for the project.

Best regards,

Tsvetinka

1. Create a snapshot of the VM instance hosting SAP CAL: In the Google Cloud Console, go to Compute Engine > VM Instances, select the instance, and click Create Snapshot.

2. Create a backup of the SAP CAL database: Log into the SAP CAL instance and use the backup utility to create a backup of the database.

3. Create a backup of the SAP CAL file system: Use the Google Cloud Console to create a snapshot of the persistent disk used by SAP CAL.

4. Create a backup of the SAP CAL configuration files: Use the Google Cloud Console to create a snapshot of the persistent disk used to store the SAP CAL configuration files.

5. Create a backup of the SAP CAL logs: Use the Google Cloud Console to create a snapshot of the persistent disk used to store the SAP CAL log files.

6. Store the backups in a safe location: Store the backups in a secure cloud storage bucket or on a separate on-premises storage system.

Hello Yogananda,

for bullet point 2: I just wrote in my first post that this feature does not work. Can you please provide steps to make it work? Thanks in advance
