Easy way to upload files from a *nix server to a Synology NAS

Yesterday finally arrived the new NAS (Synology RS409) for the SEL Lab At UC3M. The first task was to configure and make a mirror of all the data on our old file server.

There are several ways to do this by command line, for example, SCP with SSH or rsync. At least this 2 options were the first that came to my mind but they didn’t work nice.

First, SCP seems to be the best way to do this, but what a surprise!, the Synology Software DSM 3.0 have a “light” version of SSH that doesn’t support SCP.

So the next move was rsync since it was supported I thought it will be a another good way, but the problem now was the speed, rsync spends a lot of CPU usage on the checksum verification (the NAS have a small ARM processor). So instead of having speeds about 25 – 30 mb/s I got an average of 5 mb/s.

I did a little research and I found that the easiest way to do this (Without having to install anything via ssh on the NAS) was using lftp this way:

#install lftp on the old server

sudo apt-get install lftp

#connect to the server

lftp -d [remoteServer] – u [username]

#make a reverse mirroring

mirror -R [localFolder] [remoteFolderToPutTheFiles]

And that’s all.
