Please help me with the following issue.
I have two NS Servers.
One is DC-AD/FS server and the other is BKP server.
On BKP server I have created a NFS shared folder in which I want to make the backup of the DC-AD/FS server. On BKP server I have installed NFS by @stephdl .
On DC-AD/FS server I have configured Backup (data) to the NFS Share.
During the back-up process, there are some errors, even the archives are created on NFS shared folder.
TIA,
Gabriel
EDIT:
BKP is joined to DC-AD.

You are right.
I have run backup-config from console and …
Please, will you change the subject of this topic as you think?
This NS is installed from scratch with NS 7.4 beta1 ISO and updated to Samba DC 4.7.0.
The previously NS as DC-AD was updated to 7.4 beta1 and then updated to Samba DC 4.7.0. from 7.3 final and I didn’t have this issue.

I just made an “experiment”.
Because I didn’t erase the previous DC-AD NS VM Server (updated to 7.4 beta1 and then updated to Samba DC 4.7.0. from 7.3 final), I have run backup-config on it and I have the same error but all backups were OK.
I don’t know if matter but now, on the previous NS DC-AD, I saw there is available an update to nethserver-backup-config made by Giacomo on Oct 6 15:00 2017.
I will try the following:
I will make a backup on BKP Server (unfortunately I did not keep previous version) without this update to see if it works.
I will make the update.
I will make another backup on BKP Server with this update to see if it works.
I noticed something different in the Samba AD configuration on the two PDC-AD servers.
I configured the two servers in the same way.
FQDN is pdc-ad.abt.ro, the NS Server IP is 192.168.1.2, the AD container’s IP is 192.168.1.3, the same server name, the same Organization contacts, the same passwords, etc.
But:
on the server that was installed with NS 7.3 Final ISO, updated to NS 7.4 beta1 and then updated with Samba 4.7.0, Realm is ABT.RO
on the server that was installed with NS 7.4 beta1 ISO and updated with Samba 4.7.0, the Realm is AD.ABT.RO
Please see the attached photos.
What is your opinion?
I will try another thing. The easiest way. I will power up another VM.
Maybe something was wrong at installation, updates, …
I will keep you informed. It takes about one hour.
