Subject: tob:remote backup
Hey Karel,
first, I find tob a useful tool for comfortable backups.
Here some remarks concerning the remote backup:
* There's no need to "su" to another user on the local machine: An adequate
"$HOME/.rhosts" -entry (lets say for the user "tape") on the target machine
should be sufficient. As an example:
cat /home/tape/.rhosts
machine_to_be_backed_up.domain root
This allows root on 'machine_to_be_backed_up.domain' a rsh on the target
machine.
* With a gnu-versions of tar or cpio and the above '$HOME/.rhosts' -entry
a remote backup is even still simpler:
BACKUPDEV="tape@targetmachine.domain:/dev/rmt0"
(This is how I backup my Linux-box to a tape connected to
an AIX-Tapeserver.)
The tar command starts the "rmt"-command for the user "tape" on
the remote machine via rsh and pipes the stream into it. rmt is
usually in /etc and that's where tar looks for it. (However, the
tar that comes with Slackware-Linux expects it to be in /sbin.
In this case one needs an appropriate link on the the target machine
or a different tar.) Maybe afio has a similar feature.
Maybe this is of help to you. If not, simply forget it.
