I am planning to set up database mirroring of my Live principal database in the next few days. However, after reading a few confusing articles on the web, I am not too sure about the transaction Log status of the Mirrored database.
So, please can somebody tell me that if I back up the transaction log file of the principal database (which will truncate the queries that have already been run, and sent to the mirror), will this also backup the log file on the Mirror database and truncate the queries that have already been applied to the mirror?
I am effectively trying to prevent the mirror transaction log file from growing too large and need to have a way of controlling its size.
Plus, is there a way estimating the size of the mirrored log whilst it is in the 'no recovery' state?
Thanks for all the help in advance it is much appreciated!!!!
