Over the years, I've ran into various bugs that crop up in backup solutions that affect the integrity of backups. The problem is, these bugs often go unnoticed and undetected. VM's can still spin up and be tested and data can be read, so the backup software shows green and says everything is fine. However, maybe that one file or the folder of files somehow got corrupted and that wasn't being read during the test restore. Maybe this problem was introduced because of a bug in the CBT mechanism, or maybe in the VSS mechanism, or maybe the REFS file system, or maybe in the backup software. Sure, we have multiple backups but if the problem occurs in the backup mechanism itself, that means all downstream backups are bad. I really appreciate the rigorous mentally and stringent Q&A standards that Veeam takes in the development process, however, Veeam is still capable of making mistakes and shouldn't be considered above reproach, nor should any software vendor, especially your backup software vendor. And yes, these scenarios are relatively rare.... or are they? I've experienced a number of issues in my time and have developed a very skeptical view of using a single backup mechanism. All that being said, should we be using multiple backup mechanisms to insure data recovery. I' really love to be told I'm wrong or mistaken or that I'm missing something. Please, say I'm wrong! What are your thoughts?
