llias,
Glad to hear you solved your issue.

But the question still remains: Why version ATIH 2020 did not have any problem with this setting enabled in the NAS, whereas ATIH 2021 fails with this setting enabled?
I cannot answer your question definitively however, the changes made to TI 2021 with the addition of Cyber Protection are probably at work here. This also could be attributed to further enhancements to the SMB 3.0 protocol from Microsoft for Windows 10.
MSDFS = Microsoft Distributed File Service which has been replaced by MSDFS-R or Microsoft Distributed File Service Replication.
VFS = Virtual File System in Samba which is a way of creating modules for Linux based OS to use MSDFS or MSDFS-R.
I would think that since MSDFS-R is now the standard support in Windows 10 for MSDFS has been dropped thus the reason for your issue.

It seems that I have found a valid workaround for the problem!
All Acronis' support solutions unfortunately did not work. So, I started fiddling around with SMB sharing options on Synology NAS.
After various checks the culprit was found:
It was the setting "Enable MSDFS VFS module" in Control Panel->File Services->SMB-Advanced Settings in Synology NAS. This setting was somehow enabled in my NAS. After disabling it and rebooting the PC, ATIH 2021 version 30480 performed successful backups on NAS with the original backup configuration.
The Synology explanation for the setting is "This option allows symbolic links to point to other SMB servers."
This translates to /etc/samba/smbinfo.conf option in NAS "msdfs root=yes".
So, I have disabled this setting, upgraded 3 PCs to 2021 version 30480 and all backups work fine!
But the question still remains: Why version ATIH 2020 did not have any problem with this setting enabled in the NAS, whereas ATIH 2021 fails with this setting enabled?
