Backup error on exit

[Stephen White]

I just got an Exabyte Mamouth LT scsi tape drive

but if i tar

First question ?

as in tar -cvf /dev/st0 /home
it seems to work rewinds but then says
tar: Error exit delayed from previous errors

Second question

now if i
find . -print | cpio -ovB > /dev/st0

 i get truncating inode number
on some files

is there a ways to fix this an opion on cpio

Third and last

tried find . -print | cpio -ocvBH--format=newc > /dev/st0
but failed syntax

its a Redhat 7.1

Many thanks
