Full Discussion: [bash] Simple backup (cp) script but incremental
Top Forums Shell Programming and Scripting [bash] Simple backup (cp) script but incremental Post 302343640 by Franklin52 on Thursday 13th of August 2009 06:46:35 AM

This script creates directories like /oldversions/`date`/user1, /oldversions/`date`/user2, and so on.
If that's not acceptable you have to do much more work......

Create a reference file with the touch command in the /home directory and set the date and time of the file with the last copy date.
If the last copy is from 13 aug 2009 12:00 you can do something like:

Code:
touch -t 200913081200 copy.log

Now your script should looks like (not tested!):

Code:
#!/bin/sh

cd /home

find * -newer /home/copy.log -print | cpio -pvdmu /oldversions/`date`

echo "Last copy on: `date`" >> copy.log

Regards

DESCRIPTION

       The  sulog file is a record of all attempts by users on the system  to execute the su(1M) command.  Each time  su(1M) is executed, an entry
       is added to the sulog file.

       Each entry in the sulog file is a single line of the form:

	      SU date time
	      result port user-newuser

       where

       date	       The month and date su(1M) was executed.	date is displayed in the form  mm/dd where  mm is the month number and dd  is  the
		       day number in the month.

       time	       The  time   su(1M) was executed. time is displayed in the form  HH/MM where  HH is the hour number (24 hour system) and	MM
		       is the minute number.

       result	       The result of the  su(1M) command.  A ` + ' sign is displayed in this field if the su attempt was successful; otherwise	 a
		       ` - ' sign is displayed.

       port	       The name of the terminal device from which  su(1M) was executed.

       user	       The user id of the user executing the  su(1M) command.

       newuser	       The user id being switched to with  su(1M).

       SU 03/02 08:03 + pts/5 user1-root
