Hi - I've been investigating doing encrypted backups to tape using afio and gpg. Unfortunately this method proved to be extremely slow compared to the standard backup (which was expected). Someone on the debian-security list suggested looking at using a loop device such as loop-aes that is connected to /dev/nst0 as this might be faster. The only problem I can foresee with this is if there are media errors on the tape. How does the loop device cope with this? afio manages to deal with this sort of thing by spooling forward until the corrupt data is passed over and a correct magic id can be found, but presumably if the tape is encrypted a media error will lose the rest of the tape... is this true?
