Or is it just rbd snap create BACKUP rbd export BACKUP rbd snap rm BACKUP Is the snap needed at all? Or is an export save? Is there a way to make sure the image is consistent? Is it possible to use the BACKUP file as a loop device or something else so that i'm able to mount the partitions from the backup file? Thanks! Greets Stefan
