Sorry, dass es auf english ist, bin zuerst bei forum gelandet und dann gelesen, dass ich da falsch bin...
On 9 April 2024 veeam agent for linux backup stopped working.
On two machines with same error.
Veeam Agent for Windows still working fine to same QNAP target.
Two machines with problem:
Xubuntu 22.04 LTS: 5.15.0-102-generic
Xubuntu 20.04 LTS: 5.15.0-102-generic
on both machines this version:
Veeam Agent for Linux v6.1.0.1498
QNAP TS-251+ newest Firmware: 5.1.6.2722
Backup to two samba shares with two separate users on the QNAP.
So I thought this is a problem with the QNAP and restarted the QNAP, but still same problem.
Firmware update to newest qnap firmware - no improvement.
Manually I can mount both samba backup shares with
sudo mount -t cifs -o username=USER //192.168.178.255/sharename /mnt/test
or with
smb://192.168.178.255/sharename
Even a reinstall of Veeam on the Xubuntu 22.04 did not help.
But veeam cannot mount the CIFS/SAMBA, so backup fails.
So maybe there is a version issue with SMB?!
What can I try to find out what the problem is?
cifs-utils, keyutils is installed.
Thank you.
On one machine I tried to switch to NFS as a workaround, but this fails during backup file merge...
