It doesn't have to pause for the entire backup period. The impact is similar to doing a local SQL backup to disk while the database is up. > We currently have local scripts in place that put the database in a > mainteneance mode and copies data to a data directory.

You may not want to. But there are features you get from the agent. * Don't have to maintain local scripts. They can break and people can forget about them. I've been called in to places that had 4 months of "good" backups on tape that were worthless because the local script had been disabled and the files being backed up weren't current. * DBA visibility of backups, ability to restore directly. Don't have to do a file restore followed by a DB restore. DBA can easily tell which tape backup has what data on it. * No local storage required for a second copy. Can roll straight to your media device. * Agent can tie into other NBU features like Advanced/Snapshot client for low I/O impact of backup and fast restores. I'm sure there are other features that assist DBAs more than backup admins like me. -- Darren _______________________________________________ Veritas-bu maillist - Veritas-bu@mailman.eng.auburn.edu http://mailman.eng.auburn.edu/mailman/listinfo/veritas-bu
