Backup database

[Helvis]

Hello everybody. There is a problem.
When I try to do automatic backups(sample copy of account):

@echo off
set user=my_login
set pass=my_pass
set path=d:\backup
set dbname1=account
c:\windows\system32\pdate.exe "\s\e\t \d\m\=H-M" > tmp.bat
call tmp.bat
del tmp.bat
set cp_time=%dm%
mkdir %path%\%dbname1%\%date%
OSQL -U%user% -P%pass% -n -Q "BACKUP DATABASE %dbname1% TO DISK = '%path%\%dbname1%\%date%\%dbname1%_%date%-%cp_time%.backup'"

Each new backup archive has the same mass. What am I doing wrong?

Sorry for my bad english

Same "mass"? Do you mean size? If so that is normal if you are doing full backups.

If you want scheduled backups then i would use maintenance schedules to do it as you have far more options such as cleaning away old files. You can also do things like database shrinking, reorganising the indexes and (in my case) compressing my backups to 7z so they are much much smaller ;)

Yes - I meant it. Thank you.
