# This script will backup local drives to a remote tape drive over ssh.
# written by David B. Peterson <dave@toppledwagon.com>
#
# Follow these steps before using it the first time:
# 1. Configure the env variables below, especially OPERATOR, TAPEHOST
# TAPEDEV, and FILESYSTEMS
# 2. run the following commands as root (on the machine to be backed up):
# ssh-keygen -t dsa
# cat ~/.ssh/id_dsa.pub | ssh OPERATOR@TAPEHOST 'cat - >> ~/.ssh/authorized_keys2'
#
# where OPERATOR and TAPEHOST are as you have defined below.
# We will run under screen so you can come back to the backup, if you need to.

exec screen $0

# ssh-agent allows us to backup securely without entering the passphrase so
# many times. This version uses openssh v2.9
