EG: primary has: 1pm 2pm 3pm 4pm 5pm 6pm 7pm 8pm 9pm secondary has: 1pm 2pm 3pm 4pm 5pm 6pm 7pm 8pm 9pm 10pm 11pm So when you go to replicate back, it will see that 9pm is the newest shared snapshot both have, and start replicating all changed blocks after that point. If 9pm goes away, it would use 8pm instead, if 8pm is gone... etc. If you had moved to the secondary, but for some reason get the primary up and had snapshots through say, 10am the next day, everything after the 11pm snapshot on the primary would be deleted. --Tim
