[flexbackup-help] Extract problem

[Kelvin P. <kel...@ya...>]

With the help of flexbackup, I can backup files to the tape drive
I make Set 1 in /etc/flexbackup.conf
$set{'set1'} =3D "/bin /boot /dev /etc /home /initrd /lib /opt /root =
/sbin
/tmp /usr";
And start the backup using the command flexbackup -set all
The problem is, I don't know how to extract the file.
For example, I have a file in /root/bin/coWednesday.dmp.z
I use the command: flexbackup -num 9 -extract -onefile
bin/coWednesday.dmp.z
But no file extracted.
[root@intranet root]# flexbackup -num 9 -extract -onefile
bin/coWednesday.dmp.z
