Well now that my book is out of the way I am starting up some blogging again and a series on different aspects of things for v13 over the next 10 weeks (one per week). The first one is below and can be found at my blog site -
What to Check After Upgrading to Veeam v13
Introduction
A successful Veeam v13 upgrade should be treated as the beginning of operational validation, not the end of the change window. The installer may complete cleanly, but production confidence comes from confirming that scheduled backups, restore workflows, repositories, and notifications all behave as expected after the platform change.
In most environments, the post-upgrade risk is not an obvious failure. The larger concern is a subtle change in transport behavior, permissions, or reporting that only appears once the next backup cycle starts. That is why the first checks after a v13 upgrade should focus on job execution, restore testing, and anything that affects the recovery path.
Check Core Platform Health
Start by confirming that the main Veeam services are healthy and that the console or web management path reflects a stable environment. This is also the point where repositories, proxies, and managed servers should be reviewed for any components that reconnect slowly or show warnings that were not present before the maintenance window.
A practical production check is to look for small but meaningful changes: longer initialization times, repositories that enter maintenance states unexpectedly, or components that now require a trust or certificate review. None of these issues necessarily stop a job from running, but they can create downstream problems during busy backup windows.
Validate Existing Jobs
The next step is to confirm that existing jobs still start and complete normally. That means reviewing the first scheduled run after the upgrade, checking whether application-aware processing still works, and looking closely at any warning that appears new even if the final job status is successful.
This is especially important in production because backup teams often focus on failure states and miss degraded success states. A job that finishes with retries, transport fallbacks, or slower repository writes may technically pass, but it still indicates that something changed after the upgrade and deserves attention before the problem compounds.
Test the Recovery Path
A production-ready validation always includes at least one restore test. A file-level restore is fast and confirms that the basic recovery chain is intact, while a VM or application-oriented restore gives a better signal that the full workflow is still reliable after the version change.
The main goal is not to simulate a disaster. The goal is to prove that operators can still navigate restore points, mount the data they expect, and recover it inside the time window the business assumes is possible. That is the difference between an upgraded backup platform and a validated one.
Review Notifications and Reporting
After the first successful jobs and restore checks, review whatever the operations team uses for day-to-day visibility. That may include email notifications, monitoring dashboards, reporting jobs, or event forwarding to a SIEM or central log platform. A version upgrade that changes nothing operationally should still leave the surrounding visibility chain intact.
This step is easy to overlook because it sits outside the backup job itself. In practice, though, missing alerts are often discovered only after a failed backup window or a restore request arrives without warning. Reconfirming notifications early avoids finding out later that the backup platform has gone quiet in the wrong way.
Closing
The real measure of a Veeam v13 upgrade is not whether setup completed without errors. It is whether backups run, restores work, and the operations team still has the same level of confidence in the platform the next day.
Production takeaway: The upgrade is finished only after the restore path has been tested.
