I had this question after viewing how to truncate Exchange 2016 DAG DB transaction log..?
We are considering implenting a DAG environment.
How does application aware backups using products such as veeam etc impact DAG members that utilise replay lag times and passive dag members?
eg - is there a chance of replay not being healthy if for example the backup job truncates logs but the copy was in a bad state?
Should i be backing up the passive node instead?
If i backup the passive node, what happens to the logs on the active, passive and replay lagged database copies?
All very confusing.
