Restore Backup - NSDC Wont start

Support

NethServer Version: NethServer release 7.9.2009 (final)
Module: NSDC / NetWorks

Hello all! :slight_smile:
Well, i am planning some server migration and decided to test out before backup/restore, and all backups i try to restore are giving me some trouble, especially with NSDC, i cant get it to work.
I followed all the instructions here: Disaster recovery — NethServer 7 Final

Anyway, i think it has to do with a Vlan and multiwans i have currently in this server.

I have a vlan tag 20. and two wans. On the original server if i delete the vlan internet stops to work, its very wierd! :stuck_out_tongue:

So, my goal is to restore backup, with at least nsdc, the rest i can do it again easy!

Another thing i noticed is that i cant create a bridge network, when i select bridge it just changes my IP
If i try to create a Bridge with my a.d. last IP it says my IP is already beeing used.

lol, just noticed nethserver-dc is not installed.

After installing nethserver-dc i restored my backup and now its working. Kinda confused, i thought the restore would do that…

Anyway, now i have to install all stuff back to the server :slight_smile:

Still wierd Shorewall only works when i have vlan20 configured.

Btw, whoever encounters this topic let me enlighten you, maybe i can help too, first of all i did read a lot what people said here(other topics), and of course i did read this: Disaster recovery — NethServer 7 Final

Made configs backup and data backup.

1 - Fresh installed NethServer
2 - Update Software Center.
3 - Installed Steph and mmarkuz Repos.
4 - Reboot.
5 - Restored Configs (Did not mark re-install packages, only network)
6 - Made networks look exactly like before, in my case (2 Reds, 1 Green, 1 Vlan)
7 - yum install nethserver-dc (this can take a lot, be patient)
8 - Reboot.
9 - If Bridge (DC IP) didnt work, create it manually. (Networks Tab → Add logical interface). - In My case all was good.
10 - Then my DC IP was workin ok, but SSSD was not, i did again restore config, and voila… all users there.
11 - Reconfigured all my NICS (red, green and blue)
12 - Re-installed all packages from Software Center you had.
13 - Reboot. (Yup, i was pretty paranoid lol).
14 - Use Restore data to recover all your data! :slight_smile:

PS: Install one package per time, its better. Each package takes time… i dont know why, but it takes much more than when fresh installing. I guess its installing while re-configuring.

That did the trick… i rehearsed it several times in a test enviroment, i tried to install packages before config backup, i tried to restore with option re-install packages marked… believe me, i did a lot of try outs! :slight_smile:

In conclusion, listen to @Andy_Wismer and use proxmox! :laughing: :sob:
