Jan 26, 2020 at 14:58 comment added Pentium100 @roaima I do not need to append the archive, I can append the tape with a new archive. I just would like to be able to extract one small file from the tape in less than an hour and withough producing a lot of wear on the tape and head.
Jan 26, 2020 at 13:49 comment added schily @roaima Try to start with reading both man pages... I see no difference. BTW: This is not a Solaris invented option but exists since the very beginning of TAR in the 1970s. In general, it is however unfortunate that GNU tar introduced many options that are in conflict with older options of the same name from SunOS tar or star , but not in this case.

Jan 26, 2020 at 13:35 comment added Chris Davies @schily looks like the -B has different meanings between Solaris tar and GNU tar. Or I could be plain wrong. It's been a (very) long time since I last used tape.
Jan 26, 2020 at 12:56 comment added schily @roaima: Why do you like to tell tar to do multiple reads to fill a block by specifying -B? This is a non-helpful option with a blocked device like a tape.
Jan 26, 2020 at 12:35 comment added Chris Davies If you want to go down the "keep it really simple" route, I'm not sure what more you want than mt and tar -B on the tape's non-rewind device /dev/nst0. Remember that whenever you close the device you get an EOF mark so you can't update in situ, only append.
Jan 26, 2020 at 9:34 comment added schily genisofs was made by debian to create defective fileystem images. It is a bad choice in general and useless in ihis case in special, since it writes in variyng block sizes. The latter applies to its bug-free counterpart mkisofs as well.
Jan 26, 2020 at 8:44 comment added Jasen perhaps use genisofs instead of tar
