If you are just wanting to restore a single file, you can simply say:

cat <cpiofile> | cpio -id <pattern to match>

I am guessing that you want to restore the files in the directory. Thus:

cat <cpiofile> | cpio -id <directory>/*

How are you doing your backups now? In the past I've used:

find /path/to/backup | cpio -vdm /path/to/tape

Many other backup tools have appeared these days, but cpio was nice. Its features include:

- skipping bad spots on a tape
- easily backup of arbitrary listings
- better packing than tar
- ability to use multiple tapes

Cheers,

Keith
