Hi all,
I know this is off topic but probably some of you had experienced this problem as well. I have a very large mapset (19 GB) which is not compressed by using bz2 (the final tar.bz2 file was 17.2 GB). I have a backup of this mapset on an USB hard disk but I would like to create another copy in a couple of double layer DVDs (I don’t want to take any chances with the data that I have). Does someone know how to create three smaller files which I can later burn on separate DVDs?
thanks,
Jaime

If you just want to chop the file up in a way that you can put them
together later to play with it (each segment won't be usable as-is),
then use either the Unix "split" command or the "dd" command. You
can specify how many bytes to split at. See the man pages for each.

tar --help:
Device selection and switching:
-f, --file=ARCHIVE use archive file or device ARCHIVE
--force-local archive file is local even if has a colon
-F, --info-script=NAME, --new-volume-script=NAME
run script at end of each tape (implies -M)
-L, --tape-length=NUMBER change tape after writing NUMBER x 1024 bytes
-M, --multi-volume create/list/extract multi-volume archive
--rmt-command=COMMAND use given rmt COMMAND instead of rmt
--rsh-command=COMMAND use remote COMMAND instead of rsh
--volno-file=FILE use/update the volume number in FILE
... so options -L and -M should be what you are looking for?
