My problem has been solved. Now I take log backup regularly. It prevents tlog to be grown abnormally.Special thanks to Gail Shaws' links.Sun, 30 Dec 2012 21:54:34 GMTshohelr2003http://www.sqlservercentral.com/Forums/Topic1399668-391-1.aspxTaking full backups do not truncate the logs, log backup does. I have faced this issue sometime back and log backups at appropriate intervals resolved the issue as well. You can check 'log_reuse_wait_desc' in sys.databases. Go through the link Gilas has mentioned, it will help to identify and solve your issue.Sun, 23 Dec 2012 11:14:03 GMTJoy Smith Sanhttp://www.sqlservercentral.com/Forums/Topic1399668-391-1.aspx[quote][b]shohelr2003 (12/23/2012)[/b][hr]Imagine that I take one full backup at the beginning of the day and later on take four log backups at two hours interval and again take another full backup at the end of the day.How is this backup plan? .[/quote]Does it allow you to restore the DB and meet your RPO and RTO requirements? If so, it's fine. If not, it's inadequate. There's no one-size-fits-all backup plan, it has to be tailored to meet the requirements for recovery for that DB.Sun, 23 Dec 2012 02:44:40 GMTGilaMonsterhttp://www.sqlservercentral.com/Forums/Topic1399668-391-1.aspx[quote][b]shohelr2003 (12/22/2012)[/b][hr][quote]That's not enough.

Once the transaction log backup is taken, the inactive portion of the log (all its log records) will be captured in the log backup.Link given by Gail Shaw is good one to understand how the transaction log works.Sat, 22 Dec 2012 23:16:25 GMTRavi SQLhttp://www.sqlservercentral.com/Forums/Topic1399668-391-1.aspx[quote]That's not enough.

But my tlog started growing very large which cause backup file to be grown as well. I take full backup everyday once.What can I do to prevent tlog from growing? Is there any inconsistency with my backup plan?Please help me to sort out the problem.Regards,AkbarSat, 22 Dec 2012 04:12:49 GMTshohelr2003
