When the log is truncated, it is the VIRTUAL log that is truncated...not the physical log. To get the physical log smaller, you'll need to use dbcc shrinkfile to make it smaller.

Question
SQL Server 2005 LDF won't shrink
Hi,
I have an issue with multiple database on my sql server. For a while, some of them were set on FULL recovery type and some others on Simple.
We switched all of them to full and configured full and transaction logs backups. In any case, for many database, after a full and/or transaction log backup, even tho the logs get truncated, the .LDF will not shrink at all.
When I select to shrink file > logs, I can see 98% of free space. I start the job, no error, but no space freed.
I tried switching back to "simple", do a db backup, then a log backup, then a shrink, no good. Back to full recovery type, db backup, log backup, shrink, no good.
Any thought?

1. Consider the recovery model for the database. If not "simple" then SQL Server will not empty the
log files automatically, and the log will keep growing. When not "simple", only backup of the
transaction log will empty the log files.
2. After either setting to simple or scheduling regular transaction log backups, verify that the log
files are more or less empty. Use:
DBCC SQLPERF(LOGSPACE)
3. Now time for the shrink. Use DBCC SHRINKFILE, (not SHRINKDATABASE), as documented in Books
Online.
Also, there are some links and general info about shrink on
