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 (184.108.40.20666) 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:Continue reading „Backup fails with „Cannot find Linux guest credentials“ in Veeam Backup & Replication v10″
