MS SQL Permission on IIS 6

[cVz]

:'( Hello everyone,

i wrote an application that makes database backups and zips them.

Can anyone please tell me what i need to do in order to get the apllication to work on IIS 6 windows server 2003 SQL 05

1. The application works fine on machines for both XP and VISTA.
2. The application runs fine on Win Server 2003 however :

my problem is : obviously the database is in use by the web site.

How can i give my application permission to make the backup while the website is connected to the database ?

regards,

You need to issue a backup command to the SQL Server and then archive the .bak file. You never want to access the .mdf and .ldf files directly.

Use this query:

BACKUP DATABASE [DBName] TO  DISK = 'C:\Program Files\Microsoft SQL Server\MSSQL\BackUpManual\DBName.bak' WITH  INIT ,  NOUNLOAD ,  NAME = N'DBName backup',  NOSKIP ,  STATS = 10,  NOFORMAT

Note: The file path is relative to the machine running the SQL Server, not the client issuing the command

PS the DBhandler.DbWinHandler is just a class we use to connect to SQL.

should i add any of the following ?

INIT ,
NOUNLOAD
NOSKIP ,
STATS = 10,
NOFORMAT

????

What is the error you receive?

[cVz]

well it just bounces ...

No error...

however the backup file is 0 bytes

[sknake]

Well try a full backup (using the query I posted) instead of a differential backup. This will indicate if backups are working at all.
