hi,
I have the script to take SQL databases backup as below but i wish to run it using a batch file and then use the schedule task to schedule the backup.
I am using the MSDE2000 engine.
I have tried using the script at the osql prompt and it works.
Use master
go
declare @IDENT INT, @sql varchar(1000), @DBNAME VARCHAR(200)
select @IDENT=min(DBID) from SYSDATABASES WHERE [DBID] > 0 AND NAME NOT IN ('PUBS', 'NORTHWIND', 'TEMPDB')
while @IDENT is not null
begin
SELECT @DBNAME = NAME FROM SYSDATABASES WHERE DBID = @IDENT
/*Change disk location here as required*/
SELECT @SQL = 'BACKUP DATABASE '+@DBNAME+' TO DISK = ''d:\backup\jaison\'+@DBNAME+'.BAK''WITH INIT'
PRINT @SQL
EXEC (@SQL)
select @IDENT=min(DBID) from SYSDATABASES WHERE [DBID] > 0 and DBID>@IDENT AND NAME NOT IN ('PUBS', 'NORTHWIND', 'TEMPDB')
end
Thanx,
Jaison lucas.

Put this into a file called backup.sql for example. In your batch file, call osql with the -i backup.sql syntax. You'll need to run it in master with an account that's db or backup administrator on the server.
