Hi Andrej, A few comments inline.

Heck, downloading 50GB to > restore one file will always be irrational. Plus > waiting for 3 days to be able to get a file is just not acceptable. I don't agree on this point. By default, duplicity stores data in 5 MB chunks (.volX.difftar.gz) and uses indexes (.manifest) to retrieve only chunks required to restore the files you specified. > - backup running 5 days will most likely get interrupted at some > point and cannot be resumed 5 days is not that far from the theoretical maximum in your case of 3 days I just mentionned. During my tests on the allmydata.com grid I experienced a maximum throughput of 1 Mbps from Switzerland even thought my uplink is 5 times faster than that. > - Makes the whole Web Browser interface to virtual drive virtually > useless, and the whole "virtual drive" concept pointless. Yes ! This is why the great backup which just implemented by Brian Warner is so awesome, thanks Brian !
