=	MAKE SURE WHERE YOU ARE ON THE TAPE BEFORE YOU BACKUP! 
================================================================================

1. To check the machine status:
	> mt -f /dev/nrtape stat

2. To rewind the tape to the begining:
	> mt -f /dev/nrtape rew

*3. To go to the end the data:
	> mt -f /dev/nrtape feom

	repeat 1: mt -f /dev/nrtape stat
	Controller: SCSI
        Device: EXABYTE: EXB-850085QANXRC06X0    
        Status: 0x24260
        Drive type: 8mm(8500) cartridge
        Media : READY, writable, at EOD, block 564941

4. To copy data from scratch to tape:
	> cd /scratch/liu/akyel3-fmri-a/
	> gtar cvf /dev/nrtape ./* 
	or
	> gtar cvf /dev/nrtape /scratch/liu/*) 2>&1 logfile &

-----------------------------------------------
5. To list data on the tape:
	> gtar tvf /dev/nrtape 

----------------------------------------------
6. To get the data from the tape to scratch:
	a. cd /scratch/liu/
	b. check the machine status: mt -f /dev/nrtape stat
	c. foward the tape to the right place: mt -f /dev/nrtape fsf 1 (or n-1)	
	d. check the machine status again
	e. gtar xvf /dev/nrtape 
		or: gtar xvf /dev/nrtape martel3-fmri-o/*
-------------------------------------------------------------
7. To foward the tape:
	mt -f /dev/nrtape fsf 1 (or 2 ... blocks)

8. To backward the tape:
	mt -f /dev/nrtape bsf 1 (or 2 ... blocks)

(BE CAREFUL WHEN YOU USE /dev/tape, it always rewind the tape to the begining
after each command.)
