Rebuilding a server and trying to do a restore. Can restore the etc/hosts file but most of the files are not showing on the tape. Have checked the tape in another server and all the files are there. Why would this be. Using cpio -ivdum -I /dev/rct0 "uniclass/*" but don't think this is the problem.

cpio files missing

Many of the system files (like /etc/hosts) are symbolic links to the actual file in a different location.
Example:
$ ls -l hosts
lrwxrwxrwx 1 root root 36 Sep 21 1997 hosts -> /var/opt/K/SCO/tcp/2.1.0Eb/etc/hosts
I'm not a CPIO expert, but maybe there's an option to restore the links as well as the actual files?

As pmcmicha says, did the backup include the -L on both servers or only on the one where the files are on tape? Alternatively, perhaps the server where the files exist on tape have been changed to get rid of the links and replace them with the actual files?

Don't understand the theory here. Here is the situation. 2 seperate unix servers. 1 tape with files on. Read tape on one server and can see all files to restore. Put tape in the second server and read the tape and it only shows a few files. How can this have anything to do with links?
If you wanted to restore all the files on the tape, why are you passing an argument?
cpio -ivdum -I /dev/rct0
restores everything.
But are you saying that cpio -itv shows a DIFFERENT listing on this machine than it does on another?
If that's the case, is this the identical tape drive?

OK. If you see different files with a listing (itv) then there's something screwy between these drives.
Recreate the backup (either from the original or restore these to a machine that wiill read them) but this time make sure compression is shut off on the tape. This does not make sense.. same OS version ?? If not, see -H flag at
Or, try dd'ing the entire tape to a file. Can you see the files you want using THAT file with cpio?
If none of that works, recreate the tape but use one of the supertars from Microlite or Lonetar (free demo downloads will work for this):
