Oh, the joy of assymetrical internet access speed. 1MB/s down and only 100KB/s up.
I have setup cloud sync for my files. 2x25GB in Skydrive plus 22GB in Dropbox and the rest (around 100GB) went into AeroFS (which is not a cloud, strictly speaking, rather cloud sync filesystem).
To get 70 GB up into the cloud, it will take approximately 9 days. In the meantime, bandwidth throttling between those 3 services and 3 PCs, is a real nightmare. AeroFS does LAN sync, Dropbox does both LAN and cloud sync at the same time, and Skydrive, (bad word goes here), syncs only through cloud. Sad, especially taking into account, that Windows Live Sync was blazing fast over LAN.
There is setting in all of them to throttle bandwidth, but when 9 instances struggle over 1 pipe, result is disastrous. As, Forrest Gump said circa. 1995, Internet is like a box of URLs, you never know what error code you gonna get.
P.S. It is possible to run 2 different Skydrive accounts on the same server (Windows 7 in my case), each under different account/session.
