Service provider A provides customized backups service to end user C.
The backup servers run in one block. A provides C some IP addresses from
a different block and configures their ACLs to let backups be done only
from the block A is letting C use. (For instance). That's the /20.

Right. The servers are at A's premise, and C can only get to A's premise
using the public Internet... and only get through the ACLs if they use
addresses from the /20 that A is letting them use. So they *must*
advertise and use them on the public Internet in order to use the backup
service at all, if nothing else.
