Windows systems do not specify rewind or no rewind devices and only support fixed-length I/O operations to tape devices. Sybase IQ requires variable-length devices. It does additional processing to accommodate fixed-length tape I/O.
While Windows supports tape partitioning, Sybase IQ does not use it, so do not use another application to format tapes for Sybase IQ backup or restore. Windows has a simpler naming strategy for its tape devices.
For more information about fixed-length I/O on Windows, see Sybase IQ Performance and Tuning Guide.
For information on naming and specifying tape devices on Windows, see the chapter “Backup and Data Recovery” in the Sybase IQ System Administration Guide.
