Message-ID: <1990Jun14.190735.918@is.uu.no> Date: 14 Jun 90 19:07:35 GMT Organization: International Systems A/S, Oslo, Norway. Lines: 17 I have been trying all sorts of ways to speed up our backups. I do *not* want to use volcopy, I prefer doing backups on a file by file level. This leaves me with tar/cpio (NCR supported software), and gnutar/pax/afio (from comp.unix.sources archives). I have not been successful in getting any of these to stream the tape. This applies both to a 400 with a Maxtor disk and the 45/60Mb streamer and a 600 with a SCSI disk and the 150Mb streamer. The file system appears to be so slow that the backup programs fail to feed the streaming tape devices fast enough to make them stream. Are my observations correct? Am I overlooking the obvious? Any comments? -- Robert Andersson, International Systems A/S, Oslo, Norway. Internet: ra@is.uu.no UUCP: ...!{uunet,mcsun,ifi}!is.uu.no!ra
