[Issue] HBS3 - Encountered Insufficiente Space?!

[sentinelvdx]

Hi,

I'm temporary doing a backup from the NAS to a server (Wintel) via SAMBA.
When doing this job, I got the error saying it encountered insufficient storage space or I/O error on destination with error code -121

I checked the 4TB HDD drive in the server and this one is perfect, and has plenty of space as it's only backing up 1TB

I've checked and 1.12TB was copied from the 1.17TB total... How can I identify which files were not copied to review them and look for another way of copying them?

Plus would be great to be able to identify also why is not able to copy them through this method

Thanks!
