In real world scenarios do may of you enable circular logging? I have never had to replay log files and usually enable circular logging.
Also in a DAG do the transaction logs get created on each member if circular logging is disabled?
finally what is best practice for backing up databases in a dag if i have 2 active with split mounted copies of each database so db 1,2,3 are on server one with passive 4,5 and 123, are passive on server 2 with 4,5 active then I have server 3 with 1,2,3,4,5 all passive where do I back up from?
