rsync - Feb 2005 - Feature request: Being able specify that the destination should follow source directory structure.

Greetings.


If I do this:

rsync --hard-links
one.server.com::"module/somedir/images/redhat/3.0WS/en/os/i386
module/someotherdir/1.0/images/redhat/3.0WS/en/os/i386" /export/distros

I get:

/export/distros/i386/... and a conflict between the two sources.

I want for destination:

/export/distros/images/redhat/3.0WS/en/os/i386
/export/distros/1.0/images/redhat/3.0WS/en/os/i386

In other words, I would like to see an option that says to rsync to create
some of the subdirectories found in the source directory.  Something like:

rsync --hard-links
one.server.com::"distros/somedir/'images/redhat/3.0WS/en/os/i386'
distros/someotherdir/'1.0/images/redhat/3.0WS/en/os/i386'"
/export/distros

Notice the ' which would be an indicator for the list of subdirectories to
recreate on the destination.  ' is a valid character for filename, so
something else could be used, but I have put it there as an example.

Because I want to maintain the hard links, I do not want to run two separate
rsync commands to perform this copying.


Best regards,

You might be able to use two separate runs and --link-dest to get what
you want:

COMMON=images/redhat/3.0WS/en/os/i386
SRC1=somedir/$COMMON
SRC2=someotherdir/1.0/$COMMON
DEST1=/export/distros/$COMMON
DEST2=/export/distros/1.0/$COMMON
rsync -avH --link-dest=$DEST2 one.server.com::distros/$SRC1/ $DEST1
rsync -avH --link-dest=$DEST1 one.server.com::distros/$SRC2/ $DEST2

This presumes that identical files are in identical dirs.  If not, you
can use -R combined with some symlinks and --no-implied-dirs to make the
original command work like you want:

cd /export
mkdir -p links/somedir links/someotherdir
mkdir -p distros/images distros/1.0
ln -s ../../distros/images links/somedir/images
ln -s ../../distros/1.0 links/someotherdir/1.0

rsync -avHR --no-implied-dirs
  one.server.com::"distros/somedir/images/redhat/3.0WS/en/os/i386
  distros/someotherdir/1.0/images/redhat/3.0WS/en/os/i386" /export/links
