Re: dump to remote machine

Hi !
First.... I hope you want to secure your session and use SSH... right ?
Hope the script below can help you...
But you have to modify the script to dump to local tape instead of disk....
(And maybe some modification caused by the fact I wrote this for Solaris)

1.
Create an SSH keypair without a password on the machine holding the tape
station.
2.
Put the public key on the machines you want to back up, and make sure you can
log on without a password from the tape machine to the machines you want to
backup.
3.
Run the script below (on the machine holding the tapestation) with the config
file as an argument. This will give you nice dump files of the selected
filesystems of the remote machines in the specified home directory (se script
below) of the tape machine.
(As said... you have to modify the script to dump to tape instead of disk..)
The script will also mail the result to the specified e-mail address in the
config file.

--- config file to use as an argument to the script above----
#      This is the input file for

  #   Syntax of this file:

  #   Hostname/IP  -- address of target machine
  #   Autodetectfs -- use 'df -F ufs' to automatically detect partitions
  #   Include      -- partitions to include
  #   Exclude      -- partitions to exclude

  # Example:

  # testuser_(_at_)_testdomain_(_dot_)_com 130.100.31.250 Y : :
  # testuser_(_at_)_testdomain_(_dot_)_com 130.100.31.250 Y : /opt:/export/home
  # testuser_(_at_)_testdomain_(_dot_)_com 130.100.31.250 N /usr:/var :

well that is some script! - although I like this, it is quite overkill....
:(

I only need some tips on how to do a backup via ssh to the backup machine...

Something to modify this so that it works under ssh:

#!/bin/sh
/sbin/dump -0au -f /dev/nrst0 /dev/sd0a


?
