Hiya, I'd like to use Dar instead of Amanda for backing up directly to LTO-2 tapes. By looking at docs I see the following: 'If the filename is "-" *and* no slicing is asked for (no -s option) the archive is produced on the standard output allowing the user to send the resulting archive through a pipe (or into a tape device).' Now I wonder how is one supposed to e.g do full backup which should span 3-4 tapes, iow. should one pipe the whole backup directly to the tape (how?) and dar will somehow handle spanning to several tapes or it's required to define slice size? In the latter case I wonder how to tell dar to directly write to each tape sequentially and not create all the slices and then cp them to the tapes?
