Does rsync detect file corruption?

[Daniel Carrera]

Ok, thanks. Do you have any idea if a corruption that leaves the file 
size intact is common or rare? What I could do is add the --checksum 
option only once a week:

if [ `date +%a` = "Sat" ]; then
         OPT='-a --numeric-ids --delete --times --checksum'
else
         OPT='-a --numeric-ids --delete --times'
fi
...
rsync $OPT $HOME latest


Thanks again.

Daniel.
