# Back up another computer's drive to this system. To make this work,
|
|
# we need a convenient chunk of disk space on this computer. This
|
|
# version uses ssh to do its transfer, and compresses using bz2. This
|
|
# version was developed so that the system to be backed up won't be
|
|
# authenticated to log onto the backup computer. This script is
|
|
# intended to be used on a firewall. You don't want the firewall to be
|
|
# authenticated to the backup system in case the firewall is cracked.

# 2007-05-22: Changes for FHS compliance. Removed commented out
|
|
# references to ZIP drives. Now, if the archive does not exist on the
|
|
# client, we run save.metadata there.
|
|
|
|
# 2006-04-14: Use the script ../scripts/get.target to determine the
|
|
# host name. This makes the script more general, and maybe we can run
|
|
# it from one place & determine the host name from the directory
|
|
# name. Also, we now test to see if old backups exist before deleting
|
|
# them.
|
|
|
|
# 2004 04 03: added /sys to the list of excludes. It is a read-only
|
|
# pseudo-file system like /proc.
|
|
|
|
# 2002 07 01: We now set the path on the target to the zip drive with
|
|
# a variable. This fixes a bug in the command to eject the zip disk.
|
|
|
|
# 2002 07 01: The zip disk archives are now in bzip2 format, so this
|
|
# script has been changed to reflect that.
|
|
|
|
# Get the host name of the computer to be backed up and other info.
