MySQL [bash] Simple backup (cp) script but incremental
Hi all,

I would need a rather simple bash backup script that loops throught the (local) users and for each users backs up (cp!) its /home/username folder.
About the functionalities:

The script has to run every 2 hours (that's cron, so don't mind about that) and the files should be copied to the folder /oldversions/username/date-hh-mm (which have to be created every time)
Also it has to be incremental, only the modified files have to be copied to the folder. Anyways, compression (.tar, etc) is not needed!
The backups should be kept 7 days (168h) -> less important for now

As the permissions of the files&folders have to be kept, I found these lines of code that should copy preserving all this.
Code:
cd /old_dir
find . -depth -print | cpio -pdlmv /new_dir

I'm just finding my way through VBscript but still struggling with this bash scripting jobs. So thanks a lot, in advance, for helping me out!

Regards

rmf

rmf(1mh)																  rmf(1mh)

Name
       rmf - remove folder

Syntax
       rmf [ +folder ] [ -help ] [ -[no]interactive ]

Description
       The  command  removes all of the messages within the current folder, and then removes the folder itself.  If there are any files within the
       folder which are not part of MH, they are not removed, and an error message is displayed.

       You can specify a folder other than the current folder by using the +folder argument.  If you do not specify a folder, and cannot find  the
       current folder, asks you whether you want to delete instead.

       If the current folder is removed, it makes current.

       Note that the command irreversibly deletes messages that do not have other links, so use it with caution.

       If  the folder being removed is a sub-folder, the parent folder becomes the new current folder, and tells you that this has happened.  This
       provides an easy mechanism for selecting a set of messages, operating on the list, then removing the list  and  returning  to  the  current
       folder from which the list was extracted.

       Using to delete a read-only folder deletes the private sequence and current message information from the file, without affecting the folder
       itself.	If you have sub-folders within a folder, you must delete all the sub-folders before you can delete the folder itself.

Options
       -help	 Prints a list of the valid options to this command.

       -interactive
       -nointeractive
		 Asks for confirmation before deleting a folder.  By default, deletes a folder and its messages without asking	for  confirmation.
		 If  you  specify  the	-interactive option, asks if you are sure before deleting the folder.  You are advised to use this option,
		 since when deletes a folder its contents are lost irretrievably.

Examples
       This example shows how asks for confirmation when the -interactive option is used:
       % rmf -interactive +test
       Remove folder "test"? y
