I am not sure what you want here, but you're looking into taring something into tape, here's the synthax; assuming you're in a linux environment offcourse: "tar -Pcvzf ...."

Also if you can afford it bring the system to single user mode for the backup to avoid problems with open files and inconsistencies.

This backup methodology will work fine for everything except open(hot) databases.

Earlier versions of tar defaulted to the tape device without the -f tapedevice entry.

You are going to need to shut down any oracle/mysql databases prior to backing up like this.

The first tape device name is usually /dev/st0 (or /dev/nst0 for no-rewind), if you are using a normal SCSI/IDE tape drive.

If it is some other type of drive, a special driver might be required.

Check to make sure your 'st' module is installed (lsmod), and see what your console messages say with regards to 'st' devices (dmesg | grep st).
