Hi,

I want to upload my backup to another location over the internet
throug VPN.
Most files are pictures (3-10mb) and Office docs.
The slowest connection is 1600KBit p/sec.

How long wil it take to upload 100mb?

Regards,

Cookie!!

Can't tell from the connection speed. What matters is STR
(Sustained Transfer Rate), but STR cannot be predicted based only
on the connection speed. {Well, OK, we know that STR will be
less than connection speed, but how much less depends on lots
of stuff.}
 
Hi
File size is measured by Bytes "B".
Network/Internet "Speed" is usually measures by bits "b".
1Byte=8bits.
If the Internet connection is 1600Kb/sec. (b=bits)
Translating it to Bytes mean 200KB/sec. or .2Mb/sec. (B=Byte)
To transfer a 100MB file should take under the best of circumstances.
100 / .2 = 500sec. (about 10Min.)
In reality, it would take quite longer since the Network/Internet traffic
would not maintain constant pick speed.
How long? I cannot tell since I have No experience with the efficiency of
your systems.
