Your SQL Server is configured to require you to have high-level permissions (such as administrator) when you run backups on a remote server. However, you are using a hosted server, and the Internet Service Provider (ISP) won't grant you those permissions.
You can back up your remote server databases even when your ISP won't grant you administrator permission on the server. DBQuick offers you a number of additional benefits; for example, you can re-create a database to a different name, or run it on a different version of SQL Server (including the free MSDE), and you can compress the backup.
Compatibility with SQL 2000/2005/2008, Express Editions
