help back up NT and AIX using tctl comands 1

[johndrake]

Hi,

I am trying to backup both AIX/NT onto a single tape. The
problem I am having is that the tape automatically rewinds, I
believe, after the first back up is done. I need to know the
tape command so that the tape does not backup after the first
backup is complete. Here is my script:

#switch to backup directory###
cd /notes

# create log file
DATE=`date +"%d%b%y"`;
touch $DATE.log.2

# generate list of files to backup
touch /notes/unix_incremental_files
find /home/xxxxx/PERLSCRIPTS -print >> /notes/unix_incremental_files

# perform backup
tar -cvf/dev/rmt1.4 -L /notes/unix_incremental_files

# move the backed up files list to the log file
mv /notes/unix_incremental_files /notes/$DATE.log.2

# remove old files
rm /notes/unix_incremental_files

# perform backup
/tools/samba/bin/smbclient '\\Kslnas1\home2' xxxxx -U xxxxx -Tc /dev/rmt1 '\xxxxx\laptop bkp\Personal\Mandarin2' >> ./$DATE.log.2

# rewind tape
tctl -f /dev/rmt1 rewind

# compress file
compress ./$DATE.log.2

I heard that the following may work:

tar -cvf/dev/rmt1.4

to prevent the tape from rewinding but it does not. Could someone please help me?

We are using AIX 4.3.3

Thank you

use the no rewind device rmt1.1 , rmt1.4 will rewind the tape.

export TAPE=/dev/rmt1.1
mt rewind
tar c /home/staff
mt weof
tar c /home/admin
mt weof
tar c /etc
mt weof
....
....

restore::
...
mt rewind
mt fsf 2
tar x
....

mt is posix tool that does same thing as tctl in AIX on many UNIX systems
