Hi, I have a 40gb backup folder 'samples' with multiple nested folders.
I have a copy of this folder on another partition for general use.

backup :- /mnt/hda3/samples
user :- /mnt/hdb7/samples

Many folders/files from the everyday folder are now missing.
I wish to copy the missing folders/files back to /mnt/hdb7/samples folder.

I have tried cp -u /mnt/hda3/samples /mnt/hdb7 but the response is

"cp: omitting directory `/mnt/hda3/samples'"

so I tried cp -u /mnt/hda3/samples/* /mnt/hdb7 but the the next
layer of folders are omitted.

ie
cp: omitting directory `/mnt/hda3/samples/folder1'
cp: omitting directory `/mnt/hda3/samples/folder2'
cp: omitting directory `/mnt/hda3/samples/folder3'
cp: omitting directory `/mnt/hda3/samples/folder4' ... etc

Any advice on the correct usage?
I didn't want to make a whole new copy as it takes hours.

Thanks

-R, -r, --recursive
copy directories recursively

(i.e. descend into subdirectories)

That worked great, thanks
