Error during database restore

Hi,

I'm trying to restore a database backup but I get this error. What does it mean exactly?

Thanks!

what this usually means is that you backed up your database to two different files, but are only supplying one file during your restore. Is this the case? Did you create a database backup to multiple files? If so, you need all of them to do the restore.
