I've just read through a lot of MSDN documentation and I think I understand the different recovery models and the concept of a backup chain. I still have one question:
Does a full database backup truncate the transaction log (using full recovery mode)?
If yes: Where is this mentioned in the MSDN? All I could find was that only BACKUP LOG truncates the log.
If no: Why? Since a full database backup starts a new backup chain, what's the point in keeping the transactions that were finshed before the full backup active in the log?
