I think this is taken care of by the fact they don't actually send the gzip stream directly to tape. What amanda does is create "chunks" of backup data from the file systems you are backing up. Each "chunk" is separately gzipped, then that file is streamed to tape. So, in theory, a bad block on tape can be gotten around (I think). - -- Seeya, Paul -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: Exmh version 2.2 06/23/2000 (debian 2.2-1) iD8DBQE80VoCuweSOVPxKO4RAtEuAKChYZuCgTLlWKptC+sTLBE/JA29vACcCExa yzXRgCrDQOlQUK3nboage/o= =zPHc -----END PGP SIGNATURE----- ***************************************************************** To unsubscribe from this list, send mail to [EMAIL PROTECTED] with the text 'unsubscribe gnhlug' in the message body. *****************************************************************
