I'm pretty sure the 'Z' option is needed - coupled with the 'P' option that tells afio to 'compress' using an external program that happens to be gpg. I've also tried switching off compression on gpg (by adding "-Q -z0") but that doesnt speed up the backup either. Whats annoying is, I think the main slow down isnt from the encryption, its from having to start gpg for every file in the backup (afio compresses file by file). Encrypting a 4mb file on its own is relatively quick with gpg. I cant backup to a file based archive, encrypt that and write the encrypted archive to tape in case of media errors. I'm assuming that even a 1 bit error in an encrypted archive will break the whole archive, or at least the rest of the archive following the error. This is what afio is good for because a media error only corrupts the file that it occurs in, not the whole archive. [I also neglected to mention that I need to backup to tape as the tapes are taken offsite as a further security measure (in case of fire etc). This rules out backups to encrypted filesystems on a harddrive as hard drives are easily breakable (if dropped for instance)] Thanks, Marcus -- Marcus Williams -- http://www.quintic.co.uk Quintic Ltd, 39 Newnham Road, Cambridge, UK This message is private [ ] public [*] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
