VIA with iSCSI storage: no rights on the backup folder

[mr-manuel]

Hello,

I installed a fresh Veeam Backup & Replication 13.1 server on Windows Server 2025, a fresh Veeam Infrastructure Appliance 13.1 with iSCSI and mounted there a fresh created LUN from a QNAP NAS. Nothing hardened here. Now when I want to create a new backup repository I get the error "veeam-grp-backup group has no rights on the backup folder". This is very strange, since everything was installed as default. Checking the group via SSH, it's indeed another one.

I followed https://www.veeam.com/kb4822 but with no luck.

Code: Select all

[veeamadmin@veeamrep01 ~]$ ls -l /var/lib/veeam

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:

    #1) Respect the privacy of others.
    #2) Think before you type.
    #3) With great power comes great responsibility.

Seems like the default permissions are wrong? Any other fix for this?
