At Customer PJT, which was built in 2018,
I’m trying to build additional ISS Backup service, and I have a license inquiry.

The customer will probably install each backup service under admin.
In this case,
1. Do I just follow the 1st admin backup device below for the license?
2. Or should I buy a backup device channel as well?

A:
You can follow the Backup Device on the system on which the backup service will operate.
When the Backup service is registered with Admin, Admin,
When the Backup service is registered with Federation, it is Federation.
