How long (theoretically) would it take to upload a 1.65 GB file on an ADSL link with a 256KB upload speed assuming the ADSL upload is the main restriction to throughput?

Whenever I calculate these things I seem to get it wrong

Edited to add: I'm thinking in the region of 14 hours?

256kb = 25kB/sec = 100kB every 4 secs = 1.5Meg a min.

1650mb / 1.5 = 1100mins / 60 = 18hours 20 mins assuming full pelt

DOnt forget an average of about 20% overhead loss, plus contention issues.

That said, easier to just go with Jamies

or write a DVD and post it

I started sending it about 9:30.... Was just wondering if it was worth going to site in the morning. No point going if the file isn't waiting ready for me

Bloody 1.65GB .PST files... Once it's reinstated it's time to get the customer to do some cleaning out before it hits 2GB.

If its that large, its in danger of being already unstable. The psts tend to start to fail at around 1.6Gb...

Get him to archive and split off into date organised psts...

I'm well aware... I'll just be happy if I can get the file over there first

Wouldn't it be better to break it up using winzip of winrar into smaller chunks, say 40-50mb that way if something goes wrong and you've already got 1500mb and on the next file yours or his pc/connection fails you only lose that bit and not the entire 1.6Gb?

already done

256kb is actually 31.25kB/sec (1mbit = 125KB /sec) so at 25kb its already 20% under

Also, if you're FTPing it you're more than likely going to have issues above 2GB....

Depends who your ISP is, if it's NTL it might take a few weeks

Straight 'Doze file copy inside an IPSEC VPN.

In case it proves troublesome I need a fallback plan. I was thinking of putting it on our internal webserver and using a download manager to grab it from the client end?

Anyone have any better ideas or recommendations for a good download manager that can automatically recover lost connections?

It WILL fail, these things always do...

Write it to a USB key/DVD whatever, and post it - much simpler...

Add another 20% for the VPN overhead, but I can't see any reason why it should break :?
