Take the tour ×  So i have a backup system running that
basically stores all files in Dropbox using encfs. (In addition
i do a nightly rsync of the complete Dropbox folder to Amazon
S3). I'm quite happy with that solution, however i worry about
data corruption.  I have Dropbox running on about 5 machines (2
of them are not online all the time). While this is good for
having multiple copys of my files it also introduced multiple
points of failure. If any of the harddrives corrupt files for
whatever reason, Dropbox will happily sync that now corrupted
file accross all machines. Since there are lot's of files that i
don't use very often i would probably not notice in quite some
time.  So my question is: Do you have any ideas how i can
prevent this ? Notice when something happens ?  I was thinking
about keeping hash sums of all files in a db for the current
state (assuming all files are ok NOW) and then checking them
periodically but that would mean that files i WANT to change
also show up, which would make it ha
