Hi Davide,
I really appreciate your collaboration and all your suggestions.
I tested the steps you mentioned regarding the protocol versions, but unfortunately, I still couldn’t get the restore process to work on BackupPC3.
Because of this and following up on what we discussed in my previous thread (How to back up an NS8 file server with BackupPC), I decided to go ahead and test BackupPC 4 on NS8.
Now I have to confirm that this solved the issue, both backup and restore jobs are now working perfectly.
Thanks again for all your time and support,
Jamshid
