Backup only on the main, not the failover?

It seems that there is no backup done on the failover, when started on the main DMA. What if the main then is down? The backup would be lost. Or does this have to be configured somewhere?

Regards

Hi Dominik,

When you configure backup on an agent in a failover pair, the backup task should be configured on both agents identically. You can verify that by checking Windows Scheduler on both servers. The task is called “Skyline DataMiner Backup”.

If the task in the Scheduler is configured correctly, but the backup packages are not created on the standby agent, you might need to check backup logs at C:\Skyline DataMiner\Backup\backup.log for errors.

One possible problem is that the path for the backup file you configured doesn’t exist on the standby agent.

If none of the suggestions above match your case, this must be a software issue. In this case, please send us details of the issue and we’ll open a task to investigate this further.

Hi Dominik,

A backup taken from the main DMA is eligible for the backup DMA as well, that’s why there’s no backup file in the backup DMA.

As a best practice, I would recommend you to store the backup files in a shared folder in your network, instead of the DMA itself. As you said, if the server is down, you can’t get the backup file.

This DataMiner Help page will be useful for you, as it specifies how to configure backups. Please note on step 3, as it explains how the network path option works.

Hi Alexander,

that is definetly something I should check and it also sounds like an explanation also for the other question I was posting. Thank you!

Dominik
