Veeam: Upgrade issue – Warning 1327.Invalid Drive D:\

Today when we try to update one of our Veeam v8 to v9, we get this issue, and the upgrade failed.


Checking the logs(C:\ProgramData\Veeam\Setup\Temp\CatalogSetup.log) from the upgrade I see that this is related to VBRCatalog that is/was pointing to this drive that no longer exists.

“MSI (s) (2C:9C)[22:04:17:969]: Note: 1: 2318 2:
MSI (s) (2C:9C) [22:04:17:969]: Executing op: FolderRemove(Folder=D:\VBRCatalog,Foreign=0)
MSI (s) (2C:9C) [22:04:17:969]: Note: 1: 1327 2: D:\
Warning 1327.Invalid Drive: D:\”

So we need to fix the catalog issue, before restarting the upgrade.

To fix this issue, we need to change the registry where the VBRCatalog is set. To do this, we do the following tasks:

1. Stop the Veeam Services

2. Check the permissions that are set on the folder

3. Unshare the folder and move it to a new location

4. Now share the folder and reset the permissions

5. Then navigate to the following registry key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup Catalog

Find the string called CatalogPath, right-click it and choose modify

Under Value Data, edit the field to display the new location

Example: c:\VBRCatalog\ (be aware that you should select Disks with space to allocate and grow of the VBRCatalog). In our case, I create a new folder in the drive F:\VBRCatalog and then changed the registry with the path F:\VBRCatalog.

6. Restart the services mentioned above(should be Veeam Backup Service, but also Veeam Backup Catalog Data Service. Service is not in the start state because of this issue)

You can check here the Veeam KB1453 how to change the VBRCatolog.

Next, try the upgrade again, and it should pass this issue.

    There’s no ‘HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup Catalog’ sub-folder in my Windows 10 Enterprise (joined domain). Is there a way to manually remove the Console v9 so I can upgrade to v9.5? thanks.

      Hi Danh,

      We should and need to have the Veeam Backup Catalog. This is what hold the jobs and backups repository information. Do you have your Veeam Enterprise Manager install in the same machine?

    Luciano, thank you so much for these instructions! The inaccessible F:\ drive error I had was actually due to an orphaned backup repository with a vPower NFS mount point that had temporarily been used for seeding a backup to use with Cloud Connect. Even after removing the repository in Veeam\Backup Infrastructure\Backup Repositories and rebooting, the error still came up when trying to upgrade. I had to point the following Registry key: “HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Veeam\Veeam NFS\RootFolder” from it’s F:\ path back to “C:\ProgramData\Veeam\Backup\NfsDatastore\” to get the upgrade to work. This was for a Veeam B&R 9.5u4 upgrade to P1.
