backup with cpio and compress

[karbach]

for our backup we use the following as command:

find / -print 2>>/home/backup/backup.err | cpio -oc 2>>/home/backup/backup.err | compress -v 2>>/home/backup/backup.err >/dev/ios0/rstape016

My question is :how can i use CPIO and UNCOMPRESS commands to restore a given file from the tape ?

I have used the following:
uncompress | cpio -icvmu but it gives me the following as error:
cpio: Bad header - checksum error.
cpio: Not a cpio file, bad header.

do you have any suggestion, it's urgent.
Thank you.

You need something like:

zcat < /dev/ios0/rstape016 | cpio -icvmu

1.) rewind your tape

mt rewind /dev/ios0/rstape016

2.) uncompress contents from tape and pipe to cpio
uncompress < /dev/ios0/rstape016 | cpio -icvdumB
