Well you can also copy the repo-specific secret key to a save location and load 
that key to the machine which needs to restore from that borg repo :-)

You might have to look at remote storage replication if you really have too much 
data to backup. Keep in mind that restoring from a borg backup also needs some 
time as borg does not utilize all server cores so restoring a couple of TB will 
take a while.
