Found these commands useful, when dealing with Sql Server 2008 disk space allocation and log shrinking; in sql 2008 as you probably know you cannot use any more the command BACKUP LOG databasename WITH TRUNCATE ONLY as shown for example here: to obtain the same result you can do the following:
alter database [database_name] set recovery simple
gocheckpoint
goalter database [database_name] set recovery full
gobackup database [database_name] to disk = 'd:\temp\filename.bak' with init
godbcc shrinkfile (N'DATABASE_NAME_log' , 1)
go
To monitor disk space allocated, check for the usage of
EXEC sp_spaceused @updateusage = N'TRUE';
The following procedure uses the sp_spaceused procedure to list each table’s space:
CREATE PROCEDURE GetAllTableSizes
AS
-- Lists spaced used data for ALL user tables in the database
DECLARE @TableName VARCHAR(100) --For storing values in the cursor
--Cursor to get the name of all user tables from the sysobjects listing
DECLARE tableCursor CURSOR
FOR
select [name]
from dbo.sysobjects
where OBJECTPROPERTY(id, N'IsUserTable') = 1
FOR READ ONLY
--A procedure level temp table to store the results
CREATE TABLE #TempTable
(
tableName varchar(100),
numberofRows varchar(100),
reservedSize varchar(50),
dataSize varchar(50),
indexSize varchar(50),
unusedSize varchar(50)
)
--Open the cursor
OPEN tableCursor
--Get the first table name from the cursor
FETCH NEXT FROM tableCursor INTO @TableName
--Loop until the cursor was not able to fetch
WHILE (@@Fetch_Status >= 0)
BEGIN
--Dump the results of the sp_spaceused query to the temp table
INSERT #TempTable
EXEC sp_spaceused @TableName
--Get the next table name
FETCH NEXT FROM tableCursor INTO @TableName
END
--Get rid of the cursor
CLOSE tableCursor
DEALLOCATE tableCursor
--Select all records so we can use the reults
SELECT *
FROM #TempTable
--Final cleanup!
DROP TABLE #TempTable
GO
