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
