Using vSphere Custom Attributes with Veeam Backup & Replication

Most of my customers now use tag-based backup with Veeam Backup & Replication to protect their business-critical applications and services. This ensures that they no longer need to perform any configuration within the backup software to protect their workloads. Only the individual adjustments of the Guest Credentials for Application-Aware Processing have to be done in the Veeam Console. The added value you have by doing this I have already covered in another blog post.
In the ever accelerating IT world and the changes that come along with it, it is extremely important for my customers to be able to make fast and reliable statements about the data backup status of certain systems. Since we use vSphere tags to perform nearly all of our backup administration from within vCenter, it would be consistent to have the appropriate status information available at this location as well. This is where the Notification Settings within the Advanced Backup Settings come into play. How you can configure simple status updates in vCenter without installing additional plug-ins or tools, and what you should consider when doing so, I‘ ll show you below.

Backup fails with „Cannot find Linux guest credentials“ in Veeam Backup & Replication v10

Yesterday I had a scheduled update of his Veeam Backup & Replication installation with one of my customers. We planned to go from version 9.5 Update 4b (9.5.4.2866) to version 10 GA (10.0.0.4461).

As usual, I created an encrypted configuration backup before the update for safety reasons. How this works and why you should encrypt the configuration backup you can read here and here. I prefer to be a little more cautious at this point, before I have the trouble in hindsight. However, I did not need the configuration backup. The update went smoothly and without problems.

Since I carried out the update during the day, it was not possible, in agreement with the customer, to perform a complete backup run directly after the update. Therefore, I did a short functional test using the Quick Backup capabilities of Veeam Backup & Replication. There were no problems here either.

Today the customer called and reported about failed backup jobs. So I looked into it:

Version 10 GA: Unable to connect to guest OS for guest processing. Cannot find Linux guest credentials
