Question

Strategies to increase upload speed...

Asked by: asgarcymed

I need to upload 80 GB of files to an online backup server (by FTP), and my upload speed (stipulated by my ISP) is very, very low! I have an ADSL solution, and my download speed is good (330 Kbytes/s  Attention! 330 Kbytes/s = 330x8 Kbits/s = 2640 Kbits/s) but my upload speed is miserable (27 KBytes/s). Thus, I need to collect as many strategies to increase upload speed as possible.

Here are 3 strategies I found by my own:

1)Before uploading, compress files using an archive format/extension/algorithm with very high compression ratio/efficacy. I found 3  UHA (WinUHA, UHA Command-Line); 7z (7-Zip) and RAR (WinRAR).

2)Use Zapu [http://www.zapu.com/] - «an unique application that increases upload speeds by up to 900%» (they say)...  

3)Use VFTPX - Ultra High Speed FTP Client [http://www.softslist.com/download-4-9-24209.html]

I would like you to comment about this strategies and to tell other (new) strategies  to increase upload speed.

Thanks in advance.
Best regards.

You've stated the best strategy - compression. Another suggestion. Schedule it for off peak hours. A simple batch file and Windows scheduler can accomplish that with simple FTP. Personaly I am very sceptical about upload/download assistance programs and "Magicware". Seldom does it provide any real improvement.

All speed increasers (up or down) seem to work by compression.

If you have already compressed your files then these "enhancers" will achieve very little benefit if any at all.

Personally, I believe transferring that much data (even compressed to say 10%) is impracticle with such poor upstream bandwidth. At that upload speed - even with 90% compression (8gb)  - transfer would take roughly 100 hours!

Is it possible to physically send (by DVD,Tape etc) the original 80GB then perhaps just FTP incremental backups - or was this just a one off excercise?

Another option (and a very expensive one) is to increase your upstream. e.g T3 or SDSL where your up and down speeds are the same. (Although I am sure you will have considered this already).

There is only one option to increase upload speed, that is to increase avalaible bandwidth.

Now, if you compress the file you will reduce the amount of data you need to transfer, but seriousnick is correct, with 90% compression and 27KBps it will still take a LONG, LONG time.

Again, as seriousnick suggested, physical media (tape, DVD, thumb/flash drive) may be your best option.

Hello asgarcymed,
    I think you need to use an FTP client that will just simply keep uploading all the time. I think if you use compression, ZAPU may not be of much further help.  Keep your computer on 24/7 and it will only take 34 days for 80GB at 27kbps
if it is compressed to smaller size, it will take lesser time. Multi-session upload option is enabled in ftp client, but if the bandwidth is limited to 27kbps (and not defined per session), you simply cannot increase speed to more than that.

better bandwidth for upstream maybe the only solution for lesser time
Regards,

arkoak

Everybody agrees that compression is the main software-based strategy, and it would be extremely important to deal with my ISP in order to increase upstream/upload speed. Unhappily, here in Portugal, all ISP only allow ADSL solutions always with a miserable upstream/upload speed. Being in Portugal, it is impossible to have a upstream/upload speed higher than 64 KBytes/s, what is very expensive and although very slow!!

Hi,

I would say that you should compress it, fist of all and once done that you could then take the file on an external harddrive and take it to a faster network and upload it from there (such as schools and colleges and offices)

Another option is to split the files if possible using the compression tools. Then you can upload one bit from you computer, and the other from other places such as your friends internet access  and library. This is the fastest way then.

Rethink:  (when you use 6 hours or more to backup these files daily)
If it is offsite backup,  you can use hot swap SATA Hard Disk or usb external HDD, and you can
periodically store these HDD's to backup site --- daily/weekly/monthly/....  because of 3Gb/s.  
Only you concern is the delivery issue.  My experience is fast and I gain more time to focus on
another important stuffs.
