What is the probability that a file uploaded could be lost?

I think you might find this topic of particular interest and seems to have been made for you

And now the network attempts to maintain 6 copies now

What are the chances for data loss?

I made some quick calculations, but my math skills are terrible, so please correct me if I’m a complete idiot If we have a 1% chance of losing one of the minimum number of 4 copies within the time frame needed to detect and correct such losses, then we have a 1/100000000 chance to lose all 4 copies, which is really small. However, if we have 100,000 files, each 1 GB big (1024 blocks), then we would have only about a 36% chance that over any such time frames no file would get lost …
