I'm looking to boost my confidence in our backup systems beyond relying solely on the job success status. I've encountered numerous instances where backups seemed to be fine until it was time to restore them. I'm considering setting up a simple automated verification method where I drop a small file with known contents on a few critical servers. Then, I'd like to run a script on a schedule to mount the latest restore point and check if the file is there and matches its SHA256 hash. If the restore point is outdated or the file is not recoverable, I'd get an alert. I'm not trying to replace thorough disaster recovery testing, but I want to catch silent failures early. Here are my main questions: 1. Does this sound like a sensible approach, or is there a better standard practice? 2. How often do you perform restore tests (whether file-level or full VM/application)? 3. Are there any challenges you face when automating file-level restore validation?

Every month we run SureBackup on random VMs, which helps meet compliance and ensures our backups are solid. We also incorporate regular health checks to catch any issues early.
You can never be too cautious with backups. Consistent testing pays off!
We do weekly automated restore tests for critical VMs, restoring them to an isolated environment to ensure everything checks out. It’s essential to test not just backups but also business continuity plans.
That sounds like a solid approach! Testing in an isolated environment is smart.
You should also document the time it takes to restore key systems in case management wants to know.
I use Veeam to spin up backup jobs in a sandbox after running the main job. This helps test specific functionalities without affecting production. For critical systems, this is super important since you want to ensure data integrity and the absence of malware before anything goes live.
That's the gold standard for testing! But I agree that a cheaper baseline check can still provide great peace of mind.
Are you running any scans in the sandbox, or just checking boot functionality? It seems like a blend of both would be ideal.
Testing backups is crucial! I restore random files at least once a quarter to confirm everything is functioning. Remember, if you haven't tested your backup, you really don't have one!
Totally agree! Just doing random tests helps catch any issues before they become critical.
Exactly! It's not just about having a backup, it's about knowing that it works.
I do manual restore tests for a couple of my VMs every quarter and keep records of what I tested. If you're not testing, you run the risk of having no actual backups.
So you're not checking the other 48 VMs then? That could be risky!
Yeah, you definitely need to be on your toes, especially with VMs that are difficult to recover.
That sounds practical! Keeping everything compliant is key.
