Good afternoon. After upgrading to version 9.0, I lost the ability to create backups of virtual machines, both to the Proxmox Backup Server and locally to a separate disk mounted as a directory. The process freezes at 99%. I have tried absolutely EVERY method of creating a backup. None of them can get past the 99% mark. I have enough space on the storage.
I recently saw a similar problem on the forum, which was related to VEEAM. I followed the same approach: I switched a q35 machine from the "Latest" version to version 9.2+pve1, and it started working — that was before I upgraded to 9.0.6. Now I have the same problem again: all machines created on version 8.4 back up without any issues anywhere, including to PBS4, but all new ones do not.
Proxmox installed on BTRFS.
