Using scp command question

MikeL_4 — Wed, 15 Nov 2006 09:36:40 GMT

When doing a recursive scp between servers, the scp command will change and file links to a directory name and copy the entire contents of the linked directory to it.
scp -r mydir remotehost:mydir

Example, on local host:
lrwxr-xr-x 1 bin bin 16 Nov 10 04:30 latest -> 2006-11-10,0
4:30
On remote host after scp:
drwxr-xr-x 2 root sys 8192 Nov 11 05:52 latest

Is there a way to copy links as links ??

Easiest way to preserve everything is probably to use tar...

( cd localdir && tar cf - ./mydir ) | ssh remotehost 'cd remotedir && tar xf -'

I guess there isn't anything within scp to copy links as they are then ??

Whenever I have links and/or need the permissions preserved exactly....I use the tar command as shown above.

Mike,
scp is the doing the correct thing.
If it followed the links you would have to have the same mountpoint layout to copy the file to and then create the link.

So scp copied the data linked to on the original machine.

If you tar with absolute path, that is what happens. If you tar with relative path you can untar into a subdirectory and then move the data.

Can anyone tell me what the command would be to ssh to a remote host, tar up the directory and copy it back ?? I'm not sure of the syntax to do that if possible.

Essentially the same as what was shown above other than doing the ssh on the left side of the pipe:

ssh remotehost 'cd remotedir && tar cf - .' | (cd localdir && tar xf -)
