You don't say what backup software you are currently using. I'm guessing this is also MS SQL Server... either 6.5 or 7.0
Keep in mind that backing up an active DB with Backup software will require either special configurations or it will require add-on's that have licensng costs associated. This is to avoid issues with that would arise from the interruption of transaction processing, provided the backup did not simply error out on that file. There are options to avoid those costs, or to even avoid the software altogether... though I don't recommend the latter.
MS SQL Server has the ability to perform "database dumps". This is a way of backing up the specified db's by dumping the contents to a flat file, or files if more than one db. You could then take those dumps and copy them to another machine. This involves using SQL Enterprise Manager to create "backup devices" for those db's you wish to backup. Then creating a scheduled task (still within SQL EM) for each of those you wish to backup. The nice thing about these dumps is that they happen very quickly without interruption to SQL transactions.
If you have the SQL Admin Tools installed, these tools will include the SQL Online Books. Surprisingly, this has incredible wealth of information on operating SQL Server, including information on SQL commands and queries.
