Hi Thanks for reply. #1: So it's not a stop the world task. Does it ensure consistency while copying data which is parallely getting updated by application writes. Or does it mark the data to copied and ignore further updates on it.
#2: I will try sync snapshot. But just to confirm, will this be a stop the world process.
