[TriLUG] copying files

[Joseph Mack NA3T]

I want to copy all the new files in a directory to a back up 
directory on a remote machine (nfs mounted)

local machine has

/local_dir/directory_to_be_backed_up/

cd /local_dir
cp -auv directory_to_be_backed_up $remote_dir

this works fine except that the directory to be backed up 
has 10,000 files in it, at arbitary and varied depths, and 
the link to the remote machine is slow. The copy has to 
compare the dates of 10,000 files over a slow link for just 
one copy. It turns out that the comparison takes all the 
time.

However the files are updated exactly every 5 mins so I can 
quickly find the new files locally

cd /local_dir
find ./ -mmin -5 -type f | xargs

Now I only need to copy my short list of new files, one of 
which might be

file="./foo/bar/baz"

(where the depth varies for each file)

but now if I do

cp -auv $file $remote_dir

I get $remote_dir/baz

but I want

$remote_dir/foo/bar/baz

Anyone know how to copy a file and the directory structure 
it's sitting in?

Thanks Joe
