New Features

VMware vSphere 7.0.3 Compatibility

NAKIVO Backup & Replication is now compatible with VMware vSphere 7.0.3. Note that this does not also include full support for vSphere 7.0.3 and its new attributes.

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, which can lead to lost product configuration.

  • 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.

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.
