I wish to contents of 2 raw devices (unmounted portions of the hard disk)
as well as a "tar cf" dump onto 1 tape during night-time backups. I know
that cpio will do this job for me but I want to use tar for its portability
across systems. (Recent experiences have led to my doubting cpio's
portability.)
The following steps could be used :
1. dd 1st device
2. dd 2nd device with seek arg to start into tape
3. tar cf - ..... | dd with seek arg
but this would involve the tape continuously rewinding. I'm interested in
a solution that avoids this. Is my concern unwarranted ?
