We do incremental backups several times during the day. After these backups we truncate the log. The log actually gets erased during truncation. It is a temporary storage spot only. Once the backup is complete, the log is superfluous. Time your backups based on how small you want your log file to stay. Once a week is not sufficient for the type of activity you see. At least once a day is what I would run. We run four times a day as a default. Once a week is probably better for full backups.

However, my hunch is that there are many like myself who only subscribe to AccessD. For those of you in charge of the care & feeding of your SQL Server databases, how are you managing the transaction log file size? We have a very active system that has generated log files in excess of 6 GB (even bigger than the data file!). We have a weekly shrink database job that runs on data and log files, but my impression was that it just rearranges fragmented data and truncates unused pages. Is this correct? In Enterprise Manager, if I select the Restrict file growth option, will it automatically truncate old entries, or does it act like SS 6.5 and halt all new transactions until the log file is dumped? Ideally, we would like to retain any transactions that occured between nightly backups. Are there any utilities that can assist in this? If not, what is an appropriate log file size for a 5 GB database? The reluctant dba, Brett Barabash, MCP Tappe Construction, Co.
