Are you using loop back device as disks? If yes then this is expected. Loop back device mapping is gone after machine restart. You should test with real disk or lvm partition. > 2.

I am assuming that you mean copy of data hosted on the snap brick when you say copy the snap. Are you planning to use some backup software or to run rsync on each brick? > 3.
