A new version of the backup utility.
This is an evolution of the old AUTOTBACK script.
If the script is called without any command-line parameters it will check if "dialog" is installed on the system and it will start the "semi-graphical" interface, otherwise it will display the "usage parameters" and it will exit.
The command line parameters are still the same:
$autotback ACTION DIRECTORY ARCHIVE MAIL PRINTER, where
- ACTION is backup or restore
- DIRECTORY represent, in case of ACTION=backup the source (what we will backup), or the destination (where the backup will be restored) when ACTION=restore. The default value is "/".
- ARCHIVE represent the location of backup. It is usually the tape device (by default is /dev/st0), but it can also be a simple file (/mnt/disk/archive_name.cpio - if we use an external drive mounted on /mnt/disk)
- MAIL represent the email address(es) that will receive the backup report. If more than one email address is required, then, on the command line, those must be surrounded by double quotes (
"aa@bb.c dd@ee.f gg@hh.i"). The default emails are
"backupreport@xxxxxxxx.com root@localhost"
-PRINTER represents the name of the printer used for the report. The default value is empty. The printer MUST be already installed on the system!

# @(#) AUTOTBACK 3.4 08/09/12
#
# 08/06/2012 (sorin@xxxxxxxx.com) add pre/post actions, embedd dialog
# 17/10/2011 (sorin@xxxxxxxx.com) modify to use tar
# 18/07/2011 (sorin@xxxxxxxx.com) add the restore section, add command-line parmeters
# 10/08/2010 (sorin@xxxxxxxx.com) autoremove lock after 8hrs and reenable backup. remove hit report
# 28/08/2008 (sorin@xxxxxxxx.com) modified for rhel5. skip /proc /sys /tmp. send mail with the result
# modified 9/14/2000 to provide hit reporting on web site
#
# Usage: $0 backup /source /dev/destination email@notification.address (printer)
# if no source nor destination is provided, / will be saved to /dev/st0
# $0 restore /destination /dev/source email@notification.address (printer)
# when restore is called, the script will ask you to select a partial restore
# by typing a file mask. Just type Enter to do a full restore.
# if no destination is provided, the restore is performed on / from /dev/st0
# All the reports and temp files are kept in the /var/autotback directory
#
#
# Exit Codes: 0 - OK
# 1 - [ESC] pressed
# 2 - A lockfile exists
# 3 - Can't create dir (am I root? is it /var mounted rw?)
#
#
# If not provided on the commandline, set local Variables. Must specify at least the main action (backup/restore)
