This is a different subject.
I have some very large table which I will like select all the data in those tables to different tables by using select into. Also, I want to set the row count to 100000 at a time until all the rows a select into the new table with a loop. Here is the code I have and it is not working properly. Can you help?

SET ROWCOUNT 100000
DECLARE @RCOUNT INT

SET @RCOUNT = 10000

WHILE @RCOUNT = 10000
BEGIN
BEGIN TRAN
INSERT Tbl_archive2
SELECT * FROM archive

SELECT @RCOUNT = @@rowcount
COMMIT TRAN
CHECKPOINT
END
go

Dear Sir,

Is the compress backup functionaly only support Microsoft SQL Server 2008 Enterprise edition?

I tried to executed on my productin SQL Server 2008 Standard edition:

EXEC sp_configure ‘backup compression default’, ’1′;
RECONFIGURE WITH OVERRIDE;
GO

It retured error of:
Msg 15123, Level 16, State 1, Procedure sp_configure, Line 51. The configuration option ‘backup compresion defulat’ does not exist, or it may be an advanced option.

Thanks,
Edwin

Hello Zafar,

The ratio of backup depends of the data of database. Few factors like data type of data, consistency of data, whether data is already compressed or encripted decides the compression ratio. But normally comprassion is 40% to 80% of uncompressed backup size.
You can check the ratio in the “Backup_size” and “Compressed_backup_size” columns of backupset table.
Backup as well as resotre are faster on comprassed backup. The only thing that increases is CPU utilization.

Regards,
Pinal Dave

Hi Dave,

This is very interesting feature. But currently i instaled SQL 2008 Express with Tool, in the server option i see the Compress Backup checkbox, then i checked in. But it does not affect.

Then i tried your SQL statement to enable this by command. But it does not works too.

Did this feature avaiable in the express version?

Hi,
Could you make more tests with compression backups, I would like to know how much time does it take to backup a larger database (lets say 20 GB) with and without compression.

Also, it would be interesting to know how much CPU and memory is used, do you know where is the data being stored while the server is compressing the file (memory or disk)?

Thanks.
