I've asked support team to pay attention to your case, as log analysis is required to understand the root cause of this issue. Let us know how the investigation goes. Cheers!

I had the same issue restoring from a Synology 816 NAS SMB share to a Windows Server 2019 virtual machine.
In addition the backups failed intermittently with an error that one of the backup files could not be opened for reading.
The Synology log showed:
Code: Select all
../source3/smbd/smb2_read.c:259: [2019/06/25 14:32:54.285557, all 0, pid=27174] smb2_sendfile_send_data smb2_sendfile_send_data: sendfile failed for file vermeersa_dc001_backup/vermeersa_dc001_backup2019-06-25T133039.vbk (Connection reset by peer) for client ipv4:192.168.31.15:64698. Terminating
The issue seemed to occur as soon as large files were accessed on the Synology.
After a lot of wild goose chases on Google an some experimenting I found that the following settings on the advanced SMB settings in the Synology solved the problem:
Maximum SMB protocol: SMB3
Minimum SMB protocol: SMB2
Enable Opportunistic locking: On
Enable smb2 lease: On
Transport Encryption mode: Force (I suspect this is the important one)
I hope this helps
