your backup utility

Thu Jan 3 20:12:53 CST 2002

Matt:

I have to try that. Now I have another problem with
the tar command which I will CC the list:
Does tar/gzip has a file size limitation? I can only
tar -czf up to 2.0GB. I am trying to backup our NT
server which has a little over 6.0GB of data. When I
run the script with crontab it sends me an email
saying: 

gzip: stdout: File too large

What can be done to get around this. Is there another
flag I need?

Here's the script:

#!/bin/bash
#
##########################################################################
# Filename: 	backupNT
# Description:	This script will first mount the
necessary drives from 
#		the file server SERVER1 - 192.168.1.2 -  P and S
with
#		the mount command with Samba file system. Then it
will 
#		back up all the data from the drives with the tar
command.
