Tape backup is not available on Mac OS X.
Sybase software can back up and restore databases to tape drives that are compatible with Windows NT, including:
4-mm and 8-mm digital audio tape (DAT) formats
To back up a database to a tape drive:
Install the tape drive according to the manufacturer’s instructions.
This task includes installing an NT-compatible driver for the tape drive by using the Add/Remove buttons in the Tape Devices dialog box from the Control Panel. For instructions, see your tape drive and NT operating system documentation.
Start isql, and connect to Adaptive Server:
/sybase/bin> isql -Usa -Ppassword -Sserver_name
On Mac OS X, enter:
Use the NT tape device name with isql statements to name the tape drive.
For more information about using the dump and load commands, see “Examples of backing up and restoring databases”.
