Thank you vbe and del for your hints!

Sorry for answering so late. I have had to read tons of manual pages of rsync, cp, dd, cpio, tar, rsnapshot.

My question was concerning an exact backup of my HD on a USB-HD and how to do it incrementally.

@drl

Off course rsync is also a tool for external HDs not only over network.

If I am right the command I will use in future is the following to make a incremental backup - you may still prevent a catastrophe with some helpful hints:

Code:

sudo rsync -tavu --delete / /Volumes/backup_2013/

The option -t preserves modification times. -a archive mode. -v verbose. -u update (only newer files are transferred - this switch I was looking for). --delete means all files which are deleted on the source HD are deleted on the destination too. Because I asked for an exact copy of my actual HD, this is the option I was looking for.

To make the external HD bootable (MacOS Lion) I have to make some researches again ... It is for a later post. (I am not sure, whether it will possible with an encrypted HD).

To make the external HD bootable (only to make this thread complete for some MacOS X users):

First try: I opened the HD Utility in the Utilities folder. I was hoping to find something like "Make Disk Bootable", but no help. I will not claim, that there is no such "button". I simply did not find it.

I have no Install MacOS X Disk Image in my Applications Folder. My idea was, to run the installer over the external HD to make it bootable. But to download this large installer file over the App Store, just to make an external HD bootable, I thought that this is overkill. So I decided to try the following and it worked:

The old version of CCC (Carbon Copy Cloner), which is now payable, is working! I just have had to run a copy of the HD over the external HD ...

I expected from this forum, to help me to find the right switches for rsync, and perhaps tell me, how to make an external HD bootable over the Shell. Disappointed!

Hope this helps somebody out there

pmerge

pmerge(8)						      System Manager's Manual							 pmerge(8)

NAME

       pmerge - Builds a network bootable kernel.

SYNOPSIS

       /usr/sys/bin/pmerge bootfile kernel.name new.kernel

DESCRIPTION

       The  kernel, vmunix, is not bootable over the network. The pmerge utility prepends the bootfile onto the kernel image (kernel.name) to cre-
       ate a new operating system image (new.kernel) that is bootable over the network.

       Instead of a booting a network loadable kernel, it is sometimes desired to bootstrap link a kernel over the network.  In this  case,  (ker-
       nel.name)  is the name of the sysconfigtab file on the server containing the list of modules to be loaded to the client.  These modules are
       then linked to create a bootable kernel on the client.

       The pmerge utility is used by doconfig(8) to create a bootable operating system for dataless management services (DMS)  client  systems	to
       boot over the network. The pmerge utility is automatically invoked by doconfig(8) during the kernel build process and should not be invoked
       independently.

       The pmerge utility is located in /var/adm/dms/dmsn.alpha/root/usr/sys/bin on the DMS server.
