First time posting - sorry if this has been posted earlier or if there is a KB page somewhere.
Some very brief searching didn't show any hits for me.
If there are answers already please let me know.
If not I will raise a case.
Details first - question later
I am in early stages of testing / deploying Veeam Agent for Linux - downloaded the latest version just a few days ago.
Running into a couple of issues with SMB / CIFS network target for backup and recovery.
Issues appear to be center around CIFS version - specifically I have CIFS1 / NT1 disabled in my Samba configuration only allowing specific higher versions of CIFS / SMB protocol.
- Agent Version : v220.127.116.115
Source OS : Ubuntu 16.04
Initial Kernel: 4.4.0-130
initial cifs module ver: 2.08
Target SMB Server OS : Ubuntu 16.04
Agent for Linux recovery ISO Version : veeam-recovery-media-18.104.22.1685_x86_64
recover ISO Kernel: 4.4.36
During the initial backup job configuration I was unable to mount the SMB share.
Some research suggested the version of the cifs.ko module have been updated in later kernel versions and that might get me out of the weeds.
Subsequently I upgraded the Source OS kernel to latest Ubuntu HWE kernel ( aptitude install linux-generic-hwe-16.04 )
Prior to installing linux-generic-hwe-16.04 my Kernel version was 4.4.0-130 , after installing HWE my kernel version is 4.13.0-45 and cifs module has been upgraded to 2.09
After rebooting Source Server - I was able to successfully create the backup job and send the backup to disk over SMB / CIFS
Testing the recovery process involved booting the recover ISO in a new ESXi vm and attempting to mount the SMB share.
I received an error message indicating the recovery ISO was unable to mount the SMB share.
For testing purposes I adjusted my SMB server to enable NT1 SMB protocols and was able to restore the backup archive successfully.
After testing the recovery process I then reverted my SMB protocols and disabled NT1
The error message I am seeing when hitting the CIFS protocol mismatch is :
mount error(95): Operation not supported
Refer to the mount.cifs(8) man page.
Can the Agent for Linux be configured to specify the CIFS protocol to be used?
Can the recover ISO be configured to specify the CIFS protocol to be used?
Can the recovery ISO be upgraded to newer kernel version or cifs version?
Considering the massive issues with SMB1 wondering if I am missing something fundamental here.
