I'm trying to do a simple backup to an external disk and getting this error:
Backup failed for Server 'Server-name'
System.Data.SqlClient.SqlError: The media loaded on "C:\Program Files\Microsoft SQL.." is formatted to tsupport 1 media families, but 2 media families are expected according to the backup device specification. (Microsoft.SqlServer.Smo)`
Backup type: Full
Why am I getting this error and why is the message pointing to
C:\Program Files.. if the destination file is an external device?
