The Problem:- When I try to select files for backup to my CD-RW drive, using the Windows BACKUP utility, I get the message "The backup file name could not be used. Please ensure it is a valid path, and that you have sufficient access".
Resolution:-This happens as Removable Storage Management does not recognize CD-R, CD-RW, or DVD-R devices as backup pool media.
To resolve this issue, perform the backup to some other media type, for example, to a tape or to a hard disk.
Otherwise you may use a third party software like Firestreamer-RM,
it's a backup software for Microsoft Windows, which allows you to use the Microsoft Backup Utility (NTBackup) and Microsoft SQL Server Backup (SQLBackup) to back up your data directly to a wide range of backup media, such as DVD, HDD, Iomega REV™, flash memory and so on. Firestreamer-RM supports data compression and encryption, media and drive spanning, Windows Automated System Recovery, easy backup scheduling, remote media drives and more.
