[lug] recovering a tar file that spans CDs

OK, so now that I know I've made a mistake, I'd like advice on how to
recover (if possible) and what might have been a better option (for
the future.)

I used tar and cdbackup to create backups of images from my hard
drive. The resulting tar file now spans 9 CDRs.

Unfortunately, I consistently get an I/O error on disk 3 when I try to
use cdrestore to grab the files back.

This probably happened back in the days of spanning tapes instead of
disks, but I'd just like to know if it's possible to recover in the
middle of a disk set when using tar.

As a separate point, anyone have a better scheme for creating backups?
I don't mind saving to CD/DVD, but perhaps one file that spans disks
isn't the best choice, but I'd prefer to not have to sort out ahead of
time exactly which files will fit on each disk.

Thanks for any info/pointers/FMs to R/etc.
