Backup Database

[WesTurrant]

I am trying to backup my data in SQL 2005 SSMS and it gives me an error saying access denied.

Why am I denied access to my own database?

1) Are you a db_owner, or at least have the appropriate privs to the db?
2) Do you have write priv to the target location?
3) Atr other users currently accessing the database?
