The following is a list of issues, including those issues attributed to third-party products, known to exist at the time of release.
Domain controller and domain authentication issues can cause errors such as: • VM backups encounter 2129 Can’t Write errors to CIFS repositories with any transport type. • Physical machine backups encounter 2129 Can’t Write errors to CIFS repositories. • Virtual appliance (VA) backups fail with 2129 Can’t Write errors to CIFS repositories. • Physical machine shows as Disconnected in Inventory. The following lists some common situations that can cause these issues: • System Time synchronization: If any of the systems — AD server, the DNS server, and so on — is not within the allowed time drift, authentication can fail. • Domain membership: The machine may be part of the domain, as seen when you bring up the computer properties, but the membership may not be active, and may have to be reset. To check the status of the systems domain membership from the machine itself, use the command: netdom verify %computername% /verbose When a Backup Group contains two Windows 8.1 or Windows Server 2012 VMs that are clones of each other, and that group is backed up using HotAdd, only one of the cloned machines restores properly. During periods of heavy activity on the vRanger machine, HotAdd backup tasks may fail over to LAN backups with the following message. Sometimes, the LAN backups fail with the same error. Backup task using VDDK Hot-add failed: RETRY operation timed out [at xtimedwait:416] These errors can be caused by excessive resource contention, which causes vRanger message queues to become out of synch. To avoid task timeout errors, schedule jobs to avoid excessive resource contention on the vRanger machine. If rescheduling jobs is not an option, you may increase the timeout value to allow the vRanger message queues to recover from issues caused by resource contention. To change the timeout value: 1 Browse to the vRanger installation directory. By default, this directory is C:\Program Files\Quest\vRanger. 2 Open the Vizioncore.vRanger.Service.exe.config file in Notepad. 3 Search the file for CommitTimeout, and change the timeout value to 450. 5 Restart the Quest vRanger Service to implement the changes. When the vCenter User credentials are changed, the change does not take full effect until the Quest vRanger Service is restarted. In some circumstances, Changed Block Tracking (CBT) does not show as enabled for some VMs in the vRanger inventory. This issue is due to an error described in VMware KB article 2075984. To resolve this issue, perform the workaround documented in VMware KB article 2075984. When creating Hyper-V virtual machines, avoid using special characters. The [ ] (square brackets) and � (backtick) specifically should not be used. When adding a CIFS repository, the Security Protocol setting applies only to Virtual Appliance based operations. For machine-based operations, the security protocol used is determined by the Windows configuration on the vRanger machine. By default, this is NTLM. To use NTLMv2, you must edit the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\LmCompatibilityLevel to set the LmCompatibilityLevel to 5.
Taking a quiesced snapshot of Windows Server 2019 virtual machine fails. There is currently no resolution or workaround. As per VMware KB article 60395, quiescing is not supported for Windows Server 2019. When performing SAN backups of VMs created in VMware� vCloud Director� from a template, the backup may fail with the “Error: 2760 - <VIXcannotOpenDetails> VIX can’t open…” error. The VMware SAN mode transport searches for VMs by BIOS UUID. By default, all instances and VMs that are deployed from a given catalog vApps/template in vCloud Director are assigned the same BIOS UUID. For more information, see VMware KB article 1002403. To resolve this issue, perform the workaround documented in VMware KB article 2002506. When performing a quiesced backup of a Windows Server 2012 VM without using vzShadow.exe, event log errors are generated for System Reserved volumes during snapshot creation. The VMware QueryChangedDiskAreas API returns incorrect sectors after extending the VM VMDK file with CBT enabled. This issue causes the CBT filter to become invalid, possibly corrupting vRanger backups. For more information, see VMware KB article 2090639. Ensure that the patches described in VMware KB article 2090639 are applied, and follow other workaround recommendations documented in the KB as appropriate for your environment. When using the vzShadow.exe executable to perform application-consistent backups, lettered drives are required. The use of vzShadow.exe to quiesce mount points with databases is not supported. When backing up Windows Server 2008 R2 VMs with multiple disks, and the Enable Guest Quiescing option is selected, some backup tasks may fail with the “API Call failed with message: A general system error occurred: Protocol error from VMX” error. For options to resolve this issue, see VMware KB article 1037071. When using a Microsoft Storage Spaces Direct (S2D) cluster as a repository, VA-based HotAdd will fail with error “Error 2258: FATAL cifs_cant_mkdir”. Backup of Hyper-V VHD Sets is not supported by vRanger. While adding the Hyper-V host or Hyper-V Cluster in the vRanger inventory that contains a VM with VHD Sets disk, the Hyper-V host or Hyper-V Cluster gets added but remains in disconnected status. Remove the VM with the VHDS file from the Hyper-V cluster or host and then try to add the Hyper-V cluster or host to the vRanger inventory. The use of SAN transport mode is not supported when working with encrypted VMs. This is due to a VMware VDDK limitation documented here.
The vRanger Restore CD is not compatible with UEFI. Physical target servers booting into UEFI will not boot the Restore CD. To restore a backup to a physical server booting into UEFI, change the boot mode to BIOS. To do so, follow the steps below: 1 Change the boot mode to BIOS for the physical server. 3 Perform restore from vRanger. 4 After successful restore from vRanger, change the BIOS mode back to UEFI. Physical backup of Windows Server 2012 and 2012 R2 machines may fail with the “Failed to create VSS snapshot (P_VSSUTIL_WRITER_ERR)” message. This issue is often due to a VSS timeout caused by resource contention on the source server. If possible, adjust the backup schedule so that the backup is performed during a period of lower resource consumption. When deploying the vRanger physical client to a physical server, the account used to install and run the client must have administrative Log on as a service rights. If this computer is a node in a cluster, check that this user right is assigned to the Cluster service account on all nodes in the cluster. If you have already assigned this user right to the service account, and the user right appears to be removed, a Group Policy object associated with this node might be removing the right. Check with your domain administrator to find out if this issue is happening. For instructions, see the Microsoft TechNet article Add the Log on as a service right to an account. The use of dynamic disks are not supported for physical backup. If a physical backup task is performed on a source server containing dynamic disks, the task fails with the “Value cannot be null” message. When restoring to a physical server, vRanger does not lock the source or savepoint. This behavior potentially allows the un-supported practice of creating two simultaneous restore tasks to the same server. When performing physical backups of an Exchange 2010 server, the task fails with the “Failed to create VSS snapshot on the target machine (P_VSSUTIL_WRITER_ERR)” error. To protect Exchange 2010 with physical backups, install Exchange Server 2010 Service Pack 2 on the source server. When performing physical backups, if the credentials used for authenticating to the source server are changed without updating vRanger, subsequent backup tasks fail with the “Failed to acquire shared resources (Unable to connect to the backup destination.) Failed to connect to the backup destination” error. When this issue occurs, update the credentials in vRanger.
Table 8. Third-party known issues Taking a quiesced snapshot of Windows Server 2019 virtual machine fails. There is currently no resolution or workaround. As per VMware KB article 60395, quiescing is not supported for Windows Server 2019. When special characters are used in a file or folder name, you cannot see that file or folder when browsing the datastore in vCenter. This issue is documented in more detail in the VMware KB article 1015650. When creating a Hyper-V backup job, mixing VMs with Cluster Shared Volumes (CSV) and non-CSV volumes is not supported. For more information, see Microsoft KB article 2771882. Quest has not verified support for protecting Virtual Machines with 'vSAN storage policy and VVOL storage policy' configured together. Quest has not verified support for vCenter 7.0 using vSAN policies.
