Its kind of a messy problem (properties) and has lots of foot shooting 
possibilities.

https://zrepl.github.io/configuration/sendrecvoptions.html?highlight=properties#job-note-property-replication

In our case, for our bare metal restoration, we have a separate config 
file to do restorations per server/vm where there are "special cases". 
Thankfully there are not many and its all scriptable for restoration.

For the A --> B -->C when we do are offload from B to C, we pick the 
snapshots we want to send, place a hold on that snapshot and then do the 
send (1.5 day process). Zrepl cries that it cant prune the snapshot. 
Once the B-C process is complete, we remove the holds and zrepl happily 
deletes the snapshots it thinks its supposed to delete.
