But, that can happen when copying to anything... tape for instance... dump... tar... dunno about rsync whether it would survive with a good copy. But, in my case, as I said, I copy tars over NFS to other machines. So, as a fallback in that extreme example (never had that one in 14 years...but anything can happen), I resinstall the OS on a new HD and then copy back my latest backups from the other machines. So, in between an extreme case, I can recover and be running within minutes with my "DD" method.... Best regards, Jack L.
