I have often to backup a site using FTP or FTPS client. Many of FTP clients I have try but seems like I don’t find the best one for me. Until I try FileZilla Portable on my windows box. Actually I already have it for a long time, but it was rarely used. Until I remember that I have it on my hardisk and want to try it.
After using it. Wow, I was shocked. FileZilla now able to download a simultaneous file from one site. This is very good for me, because back in few years ago, I have to use a demo of a proprietary software to try a simultaneous download. But now, It’s all free. Just download FileZilla. Thanks to FOSS. 
If you are using Linux/Ubuntu:
$ sudo apt-get install filezilla
Simultaneous download:
Settings:
May be it would be better for FileZilla to be able to support simultaneous FTP connection to many sites beside simultaneous file download just from one site. Or do you have any suggestion… ??
