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

svn-fast-backup

svn-fast-backup(1)					      General Commands Manual						svn-fast-backup(1)

NAME

       svn-fast-backup - very fast backup for Subversion fsfs repositories.

SYNOPSIS

       svn-fast-backup [-q] [-k{N|all}] [-f] [-t] [-s] repos_path backup_dir

DESCRIPTION

       svn-fast-backup uses rsync snapshots for very fast backup of a Subversion fsfs repository at repos_path to backup_dir/repos-rev, the latest
       revision number in the repository.  Multiple fsfs backups share data via hardlinks, so old backups are almost free, since a newer  revision
       of a repository is almost a complete superset of an older revision.

       This  is  good for replacing incremental log-dump+restore-style backups because it is just as space-conserving and even faster; there is no
       inter-backup state (old backups are essentially caches); each backup directory is self-contained.  It has the same  command-line  interface
       as svn-hot-backup(1) (if you use --force), but only works for fsfs repositories.

       svn-fast-backup keeps 64 backups by default and deletes backups older than these; this can be adjusted with the -k option.

OPTIONS

       -h, --help
	      Shows some brief help text.

       -q, --quiet
	      Quieter-than-usual operation.

       -k, --keep=N
	      Keep a specified number of backups; the default is to keep 64.

       -k, --keep=all
	      Do not delete any old backups at all.

       -f, --force
	      Make a new backup even if one with the current revision exists.

       -t, --trace
	      Show actions.

       -s, --simulate
	      Don't perform actions.
