Announcements

Starting from NAKIVO Backup & Replication v10.11, NAKIVO no longer supports Nutanix Acropolis v5.x as these versions have reached end of life. These versions of Nutanix can still be added to the solution, VMs can be backed up and recovered, but at your own risk. The UI of NAKIVO Backup & Replication will have corresponding warnings when the change takes effect.

Known Issues

Product Usability

You may be unable to update from NAKIVO Backup & Replication v7.2 and older due to missing information in old licenses. Please contact support@nakivo.com to obtain an updated license.
It is possible to downgrade the Western Digital NAS package to an older version, but this may lead to product configuration loss.
When selecting all NAKIVO Backup & Replication users to apply a bulk action, only the users displayed on the screen are selected.
When updating NAKIVO Backup & Replication to v10.0, all logos will be updated with the NAKIVO default logo, including customized logos.
NAKIVO Backup & Replication may not display the up-to-date size of a SaaS Backup Repository immediately.
Backup Repository in NAKIVO Backup & Replication that is deployed as a VA has a size limit of 128TB due to ext4 inode_ratio limitation. The maximum file size is limited to 16TB.

Platform Limitations

Windows

If a Transporter is installed on Windows Server 2008R2 or later, it is recommended that you set SAN Policy to OfflineShared or OfflineAll.
File recovery may fail if the HDD’s virtual device node is SATA and the Transporter processing the job is installed on Windows.
Connection with the Transporter on a Windows 10 physical machine will be lost when it goes into sleep mode or restarts after installing system updates.
Microsoft Windows 10 Pro does not support VSS quiescing on Microsoft Hyper-V 2012 R2.
If an NFS share Backup Repository is created on Windows OS and has Transporter installed on a Windows OS assigned to it, this repository may become inaccessible after some time. This occurs due to the Windows-specific share permission configuration issue.

NAS

Onboard Transporters installed on NAS devices with ARM CPU do not support VMware infrastructures.
SAN transport mode doesn’t work when NAKIVO Backup & Replication is running on a QNAP NAS.

VMware

VMware VM independent disks are not supported.
For successful replication and recovery to an NFS datastore, thin-provisioned disks should be created.
Free ESXi host v7.0.2 with SSH connection enabled may not be discoverable due to unsupported SSH server algorithms. For details, refer to Free ESXi Host Cannot Be Discovered.
SAN mode is not supported for RDM disks using NPIV.

Hyper-V

CBT Driver for Microsoft Hyper-V 2012(R2) is not available.
Hyper-V on Windows Nano Server cannot be added to NAKIVO Backup & Replication Inventory.
If the same Microsoft Hyper-V VM is processed by multiple jobs simultaneously, some of the jobs may fail to create a VM checkpoint.
Issues with Integration Services for Ubuntu 12.04 Server (x64) and SLES 11 SP3/SP4 (x64) prevent connection to source VMs running on Hyper-V. Learn more.
Recovery jobs for Microsoft Hyper-V do not allow creating VMs with identical names.

Nutanix

Application-aware mode is not supported for Windows Server 2022 running on Nutanix.

AWS

Application-aware processing for Amazon EC2 may freeze when using domain credentials.
The Failback EC2 Instances action with the Original Location option selected turns off the source instance instead of terminating it.
Backup of encrypted EBS volumes may be unavailable for certain Amazon EC2 Transporter instance types.
Replica AMIs and recovered Amazon EC2 instances have the Platform attribute set to Other Linux due to AWS API limitations.
Bandwidth Throttling cannot be applied to instance backups to local Amazon EC2 Regions with a single Transporter.

Cloud Storage

iSCSI places strict requirements on data turnaround (any request must be served within 5 second time frame) that cloud storage is not always capable of keeping up with. As the result, features that use iSCSI (that is, Flash Boot, screenshot verification, file-level recovery, recovery to source) may not work with Cloud Storage Repositories or have stability issues.

Integration

Active Directory integration with NAKIVO Backup & Replication is not supported for guest user accounts.
HPE StoreOnce Catalyst integration is not supported on devices with ARM7 and ARM64 (AArch64) processors.

Reliability

With backup copy jobs, the value of the job speed on the dashboard can differ from the value provided via the Bandwidth Throttling settings.
When restarting a recovered VM with dynamic disks mounted to a Transporter, dynamic disks may not be recognized.
VMs that were recovered from encrypted source VMs with NVRAM settings modified may fail to boot.
Authentication to Active Directory using NTLMv2 cannot be performed.
Deployment of source Transporter and source VM from the same Windows VM template may cause backup corruption in HotAdd mode.

Feature Limitations

NAKIVO Backup & Replication features require certain conditions to function properly. For more details about feature requirements, refer to the corresponding articles in the User Guide. Below is a list of feature limitations.

Backup and Replication

VMware VM RDM disks are supported only in virtual compatibility mode.
Backed-up RDM disks in virtual compatibility mode are recovered as thin disks.
Replicas of VMs with RDM disks in virtual compatibility mode are created with thin disks.
First Class Disks (FCDs) cannot be backed up if they are not attached to any VMs.
VSS quiescing is not supported for encrypted VMs.
LVM logical volumes in a thin pool are not supported for physical backup jobs.
An encrypted Amazon EC2 instance (default key) can not be replicated between accounts.
Replication across different AWS account types is not supported.
Cluster Shared Volumes (CSV) are not supported for backup of physical systems.
Windows failover clusters are not supported for backup of physical systems.
Backup and replication of Microsoft Hyper-V VMs with shared drives are not supported.
Linux Transporter should be used for replicating/backing up VMs with SATA disks.
The progress bar may not show accurate data during file share backup due to the lack of pre-indexing and taking snapshots steps in the backup process.
When copying a compressed backup between a Backup Repository and tape device, different compression levels may cause very slow transfer speeds. For more information, see this article.
SCSI or PCI passthrough devices are not supported for backup or replication.
To run backup jobs on NAKIVO Backup & Replication that is installed on FreeNAS\TrueNAS, the Transporter VA must be deployed on ESXi.
Replica/recovered VM disks are always created as lazy zeroed if the source VM has both lazy and eager zeroed disks.
Windows transporter does not have capabilities for handling Linux physical machines.
Linux transporter does not have capabilities for handling Microsoft Hyper-V.

Real-Time Replication

When creating a storage policy, the I/O filter storage providers must be online for the vCenter to confirm I/O filter installation status.
It is not possible to add, change, or remove the I/O filter policy for any VM with a snapshot tree associated with it.
If the source VM stores disks on an NFS v3 datastore, the Transporter specified on the Options page of the Real-Time Replication (Beta) Job Wizard for VMware must be located on the same host as the source VM.
The Transporter and VM replica must be located in the same vSAN datastore.
For one real-time replication job/real-time replication failover job, each target Transporter can support up to 11 source VMs in case there is one disk per source VM or up to 50 disks per source VM. For more information, see this article.
Real-time replication does not take into account the priorities of other jobs.
If the Transporter is accidentally shut down during the real-time replication stage, the attached disks (journal & replica) are not detached automatically.
If the Transporter is migrated during the real-time replication job run, the hot-added disks are deleted and the existing replica cannot be used again during the next job run unless the existing replica disks are manually readded on the user's side.
VMs with IDE disks are not supported for real-time replication.

Exclude Swap Files and Partitions

Windows dynamic disks are not supported.
Physical machine backup is not supported.
Linux swap files are currently not excluded. Only Linux swap partitions are supported.

vSphere HotAdd

If HotAdd cannot be enabled for at least one disk of a source VM (even if the disk is deselected in the job), HotAdd may be unavailable for all disks of the VM.
HotAdd is not available for VMs that contain IDE disks.
VMware vSphere HotAdd is not supported if the VA with NAKIVO Backup & Replication has the same BIOS UUID as the source VM.

Encrypted Repository

Encrypted repositories are not supported with RHEL/SLES due to missing required packages.

Screenshot Verification

NFS datastores cannot be used as target datastores for screenshot verification.

Custom pre/post-job scripts are unavailable for Windows VMs when Integration Services are used on Hyper-V 2016 and above.

Flash VM Boot

ESX/ESXi hosts enable binding the software iSCSI adapter (HBA) to VM Kernel network(s). If such binding is configured for an ESX/ESXi host that is used as a target for Flash VM Boot, the connectivity between the host and the Transporter might not be available at the iSCSI layer.
If an iSCSI binding is configured for a host to be used as a target for Flash VM Boot, verify or configure the connectivity at the iSCSI layer (either by selecting a host without binding, removing binding on a host, or adding a dedicated VM Kernel network to the binding that allows the connectivity).
NFS datastores cannot be used as target datastores for Flash VM Boot.
Flash VM Boot may fail for ESXi hosts configured to enforce iSCSI Header Digest and/or Data Digest settings.
VM templates are not supported for Flash VM Boot.
Flash VM Boot to vSAN datastore is not supported for VMs with disks larger than 2TB.

File recovery from LVM volumes is not available when the Transporter that is assigned to a Backup Repository is installed on a NAS such as Synology, QNAP, Western Digital, or ASUSTOR.
File recovery from systems that use Windows-only features, such as Windows Data Deduplication or DFS, is available only when the Transporter assigned to a Backup Repository is installed on a Windows machine with these features enabled.
File recovery is not supported for source VMs on RAID disks.
- ASUSTOR NAS
- Red Hat Enterprise Linux 7.x
File recovery from Windows Dynamic Disks is not supported for the following platforms:
Recovering files to an NFS share fails if the NFS server is configured as NFSv4 only, and the Transporter has earlier NFS protocol versions.
File recovery may skip empty folders from the NTFS file system in certain configurations.
File recovery fails if the HDD's virtual device node is SATA, and the Transporter processing the job is installed on Windows
File recovery for thin provisioned logical volumes is not supported.
File recovery may be unavailable on some Linux configurations with XFS or BTRFS file systems.
File recovery is not possible if a backup contains an incomplete set of disks that are a part of the spanned volume/dynamic disks/LVM/RAID software or any other disk structures.
File recovery may fail if the Windows machine to which you wish to recover items has over 20 disk volumes (with and without drive letters).
File recovery may fail to display the contents of disks containing over 1 million files.
Symlinks in Windows and Linux OS, as well as encrypted files, are not supported for file recovery.

Recovery of mailboxes is not supported for Microsoft Exchange Server object recovery jobs.
Birthday events may not be recovered via an object recovery job for Microsoft Exchange Server even if the job run was successful.
Microsoft Exchange Server contact and calendar items are not supported for downloading to a browser or forwarding via email (Expert Mode).
Recovery of DNS entries is not supported for Active Directory.
For Active Directory object recovery, each recovered object has a new SID generated by the system. Due to Windows limitations, it is not possible to change it back to the original SID.
Object-level recovery is not supported for encrypted and signed email messages.

Cross-Platform Recovery

Cross-platform recovery may not work if a VM or physical machine includes a special OS kernel.

Site Recovery

PowerShell scripts are not supported for Site Recovery actions. All Windows scripts are run by cmd.exe.
