NAKIVO Backup & Replication v11.2.1 adds full support for Proxmox VE 9.2, along with two fixes affecting Proxmox backup jobs. What's new for Proxmox VE: Full support for Proxmox VE 9.2 Fixed an issue where backup jobs could fail while creating temporary overlay files Fixed an issue where a source VM could crash after a failed backup when a manual snapshot existed on the Proxmox VE host Also included in v11.2.1: Support for VMware vSphere 9 in Real-Time Replication workflows For mixed environments, v11.2 also introduced several capabilities: OAuth 2.0 support for email configuration Support for Ceph S3-compatible storage as a backup target Proxmox VE change-tracking reminder: Native change-tracking behavior depends on the VM disk format: QEMU: The dirty bitmap persists across VM restarts, allowing incremental backups to continue using native change tracking. RAW: The dirty bitmap is non-persistent. Restarting the VM resets it, so the next incremental backup uses NAKIVO’s proprietary change-tracking method. We recommend updating NAKIVO Backup & Replication to v11.2.1 to add Proxmox VE 9.2 support and apply the latest fixes. Update to v11.2.1 Now

Hi @Gavino,  Thank you for confirming that the hotfix resolved the certificate issue. This will help other users experiencing the same problem.

Hi sorry for the delay. I just wanted to confirm that this fixed the certificate issue for the Nakivo transporter on my x86_64 on my QNAP NAS - thank you.

Hi @Gianluigi, Please check whether there is any disk maintenance (e.g., defragmentation) running inside the machine, as this could affect the disk system at the block level and the incremental backup size.
