Yes.

The difference between /dev/st0 and /dev/nst0:

   /dev/st0 is the *rewinding* tape device.  The tape rewinds on the
   completion of all operations.  You'll overwrite data.

   /dev/nst0 is the *non*-rewinding tape device.  The tape doesn't
   rewind unless explicitly directed to (mt -f /dev/nst0 rewind).

Peace.

Change the first /dev/st0 to /dev/nst0 perhaps.
When you use /dev/st0 the device is rewound on close.

See also 'mt' for operations on the tape drive line rewinding or
unloading.

trouble dumping whole filesystem to tape /sbin/dump

2002-01-09 Thread Thedore Knab 
Hi,

I am trying to use dump to backup some data.

I have been using this command:

/sbin/dump -0ua -f /dev/st0 / -L slash 2>> output.txt

followed by:

/sbin/dump -1a -f /dev/st0 /usr -L usr 2>> output.txt

When I do a restore -t 

The second comand rewrites over the data I recorded with the first
command.



I want to dump the whole filesystem to the tape.

How would I do that ?

My filesystem. 

#/dev/sda5   /   ext2defaults
1 1
#/dev/sdb5   /home   ext2defaults
1 2
#/dev/sdb1   /usr/local/blackboard   ext2defaults
1 2
#/dev/cdrom  /mnt/cdrom  iso9660 noauto,owner,ro
0 0
#/dev/sda9   /tmpext2defaults
1 2
#/dev/sda8   /usrext2defaults
1 2
#/dev/sda6   /varext2defaults
1 2
#/dev/fd0/mnt/floppy autonoauto,owner
0 0
#/dev/sda1  /boot   ext2defaults
1 1
#none/proc   procdefaults
0 0
#none/dev/ptsdevpts  gid=5,mode=620
0 0
#/dev/sda7   swapswapdefaults
0 0

Sample output.
