In short: Server1 data backup to NFS, remove data backup HDD and plug it into Server2 (can’t be on the network together with Server1), Server2 restore data backup from locally mounted HDD = impossible?
I’m moving my server from one hardware to another. What I’ve done so far:
- Create new NethServer on new hardware from ISO
- Copy config backup from old hardware server to new and restore it (with reassigning NIC)
- New NethServer is working well with all services including AD
Now I’m trying to back up all data and move it to the new hardware. Since my old server is still running (providing services to many users), and all of it’s IP settings are identical to the new server – I can’t have them on the same network at the same time.
So, I decided to plug into my network another Ubuntu computer with extra temporary HDD shared via NFS. I was able to use duplicity procedure and backed up all data to that 3rd computer HDD.
Now I unplugged HDD from Ubuntu computer and plugged it into the new server hoping to restore that data backup… But, there is no way to do it. Although I mounted the backup HDD with new NethServer, it is not available as an option to restore from local backup (of course, first I’m trying to create new scheduled backup on the local disk but the mounted disk it’s not showing).
The disk was formatted to EXT4 and backed up through NFS share.
It looks like data backup isn’t as flexible as config backup. You can’t just enter the backup section and choose to restore from anything you want.
What would be the best way for me to restore my data into the new server created from scratch with imported config (and both can’t be on the same network at the same time… and old server must be on 24/7)?
