Our system is AIX 5.1.
1. I wrote a srcipt to tar FOUR directories:
tar -cvf /dev/rmt0.1 / >> /logs/coldbackup
tar -cvf /dev/rmt0.1 /usr >> /logs/coldbackup
tar -cvf /dev/rmt0.1 /var>> /logs/coldbackup
tar -cvf /dev/rmt0.1 /opt >> /logs/coldbackup
However at the end I found it tar ALL the directories in my system, such as /tmp, /abc, /def, ....etc. So what's the problem? I shouldn't put tar / (root) in the script? if there is alternative method to backup / ?
2. I saw there is some limitation on using tar to backup the file size which is bigger than 2 G, so how to solve?
