Always on availability group -HADR Questions &Answers

What about a sync mode secondary replica of always on availability group goes offline for 3 hours and come back online it self?


Once the secondary replica server goes offline ,data movement between replica would not happen and hence the transaction log on primary grows and keep on accumulating transactions.
This would cause log file to grow;So please make sure to you have enough space in place for the log file drive in the primary replica server.

Once secondary server comes online , always on group will synchronise itself to make sure primary and secondary data in SYNC Without data loss.

No need to resume manually Always on availability session .MANUAL RESUME is used in manual/ planned failover.
