I am currently using wget -m to mirror a remote FTP but the speed suck, what are the good alternative (command) so we can parallel to download in order to boost the speed up?

    Do you have any control over the remote FTP? Or does it offer rsync? That would be much more efficient depending on the data set you like to mirror.

Take a look at lftp. It's quite a powerful ftp client that has an option for parallel downloads:

'mirror' can download several files in parallel (--parallel option) and a single file with 'pget' (--use-pget-n option).

It's available in standard debian's repository so you should have it as well in ubuntu without using 3rd party binaries or compiling it from source.


As mentioned by pQd lftp is a great tool for that and it's included in "all" distributions.

lftp -u user,pwd -e "mirror --parallel=3 --verbose /$REMOTE_DIR /$LOCAL_DIR" $REMOTE_HOST

You can run it several times with time and different values of --parallel to find the best value.

    Worth adding here that mirror -R will mirror the local directory on the ftp server.
