When you perform a backup it fails with the following error " The database trasaction was rolled back" The job does run and appears to fail at the end.
The reason this issue occurs is that the host has a unseen component attached to the VM. It is not an component that can be seen.
Please follow these steps to correct the issue.
1. vMotion the VM to a different host in the cluster
2. Run the backup job once again
3. It is recommended to clean up the repository storage via windows explorer because upon job failure a VM directory is created on the repository storage and the folder contains the savepoint.manifest and VMconfig files. Because vRanger does not know about these files, the folder and files will not be cleaned up by vRanger and will need to be cleaned up manually. The files should not cause an issue with the free space on the storage because they are small but can cause confusion in the future as to why they are there.
