Question

Unable to Backup stateful application

A

Hi Team,

We are currently testing backup for a stateful application, and we have deployed WordPress and SQL Server.

For the backup process, we are using a blueprint. We created a blueprint for SQL Server and bound it to the SQL Server namespace.

However, when attempting the backup, we encounter the following error:

Job Execution Failed

Failed to prime the snapshot session
Failed to prepare Kopia backup session
Failed to initialize Kopia API server
Two errors occurred
Error Details:

Failure during the snapshot cleanup phase. Snapshots might be orphaned.
Currently, there is no CSI driver available for Azure Arc AKS, so we are trying to perform the backup using the Kanister blueprint instead.

Please have a look and let us know if there are any suggestions or solutions.

Hi ​@asharma15, 
   Thankyou for posting the error. Could you please share the full error message and the blueprint that you are using currently.

I deployed the MySQL server and blueprint from the Kasten documentation. Here are the links:

MySQL installation:
https://docs.kasten.io/latest/kanister/mysql/install.html#:~:text=Install%20the%20MySQL%20chart%20from%20the%20bitnami%20Helm%20repository%3A
 

MySQL blueprint creation:
https://docs.kasten.io/latest/kanister/mysql/install.html#:~:text=The%20following%20command%20can%20be%20used%20create%20the%20MySQL%20Blueprint%20in%20the%20Veeam%20Kasten%20namespace.

After successfully deploying MySQL, I went ahead and deployed WordPress, which is now working with MySQL.

Before creating WordPress, I tested the MySQL backup, which worked fine. However, after deploying WordPress, I am encountering the following error:
