We are wanting to put in a cold spare system at a remote location. This location is 6 hours away and if they go down it would not be good. I have live backups done daily.
I am thinking of putting a cold spare up there. The cold spare would be slightly different hardware so a config restore will reassign nics. There is also the job of keeping the cold spare up to date so the restore would work.
Devices are in router mode.
My thought is to have a cold spare configured with static ISP IP on external and a different internal IP than the core router. This would then allow the device to get updates and allow me to connect to it and restore the backup.
After restoring the backup I would assume all that would have to be done is to find out what NIC got internal and what NIC got external.
Do you think this setup will work?
