How are the files I have stored on Dropbox backed up by Dropbox? In other words, if the server that my files are on crashes, how does Dropbox restore the files? I am asking because I was asked by the Board of my non-profit if our membership list (Excel) is backed up. I said it was stored on Dropbox. They asked, how does Dropbox back up its servers?
I tried researching this myself, but every inquiry that mentions the word "backup" yields search results about how I can use Dropbox as a backup service for my own files. That is not what I'm asking.
I can find plenty of information on the steps Dropbox takes for security and privacy, but I can't find any statement about how Dropbox backs up its servers. I just need a paragraph stating that they do it (even though I know that of course they do it).
