Default Span backups

Many of you know me as an OpenBSD user but the problem I am trying to solve is not unique to OpenBSD. Namely over the years I aggregated about 50-60 GB of pictures and videos of my kids and family which is the most valuable data I have on my computers. I used to backup that videos periodically by burning additional DVDs once I accumulate another 4.xxx GB of data or whatever it can be burned on the typical DVD and send it to multiple family members/grant parents so that in the case of disaster I can recover. At this point I would like to have a script which will automatically split 60 GB of data into the chunks appropriate for writing on DVDs which I will store in safe deposit box. I am familiar
Code:
split
. However I would like to do this splitting and writing on the fly without the need for additional HDD to store those chunks. I also know that our own jggimi asked similar question on misc@openbsd circa 2004 when he wanted to write dumps across many DVDs. Could people kindly share their expertise in this domain. I am also open for other suggestion for permanently archiving my photos.

You may want to look into sysutils/shunt, which I used to use for this purpose. You can contact its $MAINTAINER if you have any questions.

I haven't used optical media for backup in a very long time, and these days, my critical data is backed up commercially via sysutils/tarsnap.

That worked as a charm. Maintainer was extremely responsive . I would like to worn people against blindly cutting and pasting commands from the package website

as they are written for Linux. Tar is actually gtar and cpio have Linux specific options. I have not played enough with pax.
