I was running full multiple database backup. For some database it created the backup file properly & for some it cant. In the Redgate log file contains the folloing mesage:

8/25/2009 10:00:02 PM: BACKUP DATABASE [AG_IW] TO VIRTUAL_DEVICE = 'SQLBACKUP_FF2D8D54-5AF5-48FE-9C6A-C8A606DD29C0' WITH BUFFERCOUNT = 6, BLOCKSIZE = 65536, MAXTRANSFERSIZE = 1048576, NAME = N'Database (AG_IW), 8/25/2009 10:00:02 PM', DESCRIPTION = N'Backup on 8/25/2009 10:00:02 PM Server: D111SQL01\D111SQLI02 Database: AG_IW', FORMAT

Can somebody explain why is it happening?
