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