Hi. I may need to understand more on the failover option FORCE_FAILOVER_ALLOW_DATA_LOSS
1. Suppose I am failing other to a ASYNC node, I need to use FORCE_FAILOVER_ALLOW_DATA_LOSS. After doing that, the original replica database are suspended in data movement. Suppose we should resume the data movement. Any case that the resume data movement will fail ?
2. If the data really checked not ok in the ASYNC node , and want to use back the original replica one . how to do this ?
3. Suppose I have 4 nodes on AG replica, in DR which are set to ASYNC. In some case in customer DR drill , they would like to use open one of the DR replica database for DRILL test. What's the fastest way to rebuild this replica after drill? Is it by doing full database backup (or copy_only) from that replica before drill + restore log backup from primary replica ?
4. How to check how much data loss on ASYNC node ?
