Veeam Fails to start after upgrade to v12
We had VB&R and it worked fine for a few years. We use it for backup 2 VMs from Microsoft Hyper-V server (free product also). Then I decided to upgrade VB&R to version 12, and it stop working with this error: "One or more critical product files have been modified. Please roll back changes or reinstall the product." I hit OK and console is closing. I tried to uninstall v12 and install v11 again, but it can't connect to MS SQL instance. Then I uninstall v11 and install v12 and it creates PostGres SQL instance. But the error still exists. What could I do with that?

Hello,
Please continue working with our support team, it does not look like as a known problem and our possibility to troubleshoot the technical issues over the forum posts is very limited.
Thanks!

Re: Veeam Fails to start after upgrade to v12
New details. After I install v11, I had problem with "Failed to create database VeeamBackup. Create failed for Database 'VeeamBackup'."
Solution already exists and described here: veeam-backup-replication-f2/failed-to-c ... 32288.html
Now, when I try to add Hyper-V server (which backuped fine before my upgrade attempts) - I receive following:
Backup server version 11.0.1.1261 is not compatible with Installer service on 'hostname'.
But I already uninstalled Veeam components from my server. What is the problem?

Re: Veeam Fails to start after upgrade to v12
Well. Perhaps this will be useful to someone. The support did not answer, the case was closed. I had to resolve the issue myself. Quite by accident I noticed that after installing v12, there was a message that it was installed 'partially'. After reading about 20 log files, in one of them, in the middle of the file, I found an error that there was not enough disk space. It turned out that the installation requires at least 30GB and therefore the cumulative patch was not installed, which caused the error "One or more critical product files have been modified". After adding the disk space, I installed the cumulative patch manually and the error disappeared.
Therefore, my wishes to the developers:
a) check for available disk space before installation (this is a basic feature and I wonder it not exist)
b) report installation errors more clearly.
Thanks.

Both requests above ( a) and b) ) are absolutely valid, I'll share it with the team.
Thanks!

Re: Veeam Fails to start after upgrade to v12
Than yoarsagera!
I had the same issue. The Veeam 12 installation/upgrade finished with the message "Upgrade succeeded partially", referring to the installation log files to find more info...
After some searching in the many files I found this in one of the log files "15:00:41.1985 *** ERROR *** There is not enough space on the disk."
Please Veeam developers, introduce a space check and report errors in a better way.

Re: Veeam Fails to start after upgrade to v12
I should also be a good thing to be able to re-run the upgrade after freeing up the required space. I can't find out if some components or hotfixes are missing after the failed upgrade.

Re: Veeam Fails to start after upgrade to v12
I can confirm that this is still an issue, and the log drops this message:
System.IO.IOException: There is not enough space on the disk.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
at System.IO.File.InternalCopy(String sourceFileName, String destFileName, Boolean overwrite, Boolean checkHost)
at HotFix.FileOperation.InstallNewFile()
at HotFix.HotFixOperation.Install()
Thanks for the heads up

Re: Veeam Fails to start after upgrade to v12
No installation should ever be left in a "partially successful" state. Either successful or failed followed by a rollback. If this would be a "new feature" then please count this as a +1 towards such a feature request.

Re: Veeam Fails to start after upgrade to v12
Well, in this case "partially successful" means "failed", because program do not work. And Itss very strange behavior for such mature product

Hello,
We research the issue but we'd like to know whether you @DanielJ @ksl28 @OskarL tried opening support cases for it? If yes, please share support case ID-s. It could help us to find the root cause faster.
Thanks!

Re: Veeam Fails to start after upgrade to v12
Hi,
I never created a support case for this, since i was experiencing this on the community edition.
But its fairly easy to reproduce - just download the newest version of VBR with a patch included.
Then ensure you have enough space for the Veeam installation + approx 5-10GB on the disk you try to install it on.
The installation will then fail, even if there is enough space on the disk

Hello,
In 12.1, we'll show the recommended amount of free space in the wizard, we expect that it will help to solve most of the issues related to the lack of free space.
Thanks!
