how to backup a file?

Hi, expert,

how to bakcup a file from a hp box to the tape of another dec box?

Thanks

You can do something like this:

find . -print | cpio -ocBv | remsh remote_host dd ibs=5k obs=100k of=/dev/rmt/0m

You will need to use the appropriate tape device on the remote host and enable remsh's by setting .rhosts and hosts.equiv. If you like, you can substitute tar or fbackup for the cpio command.

man find, cpio, remsh, dd for details.

You might export the file system under NFS and mount it on the DEC box, dumping it to tape from thence...

Clay,

that's possibly the dodgiest command I've ever seen.

I never would have thought of piping stuff into remsh.

I'm going to use that I think.


Thanks

Scott.

sunny,

Can you tell us what DEC box you have and what OS it is?

The concern is that some DEC os's are BYTE-SWAPPED.

My dex box is trux 5.1 , hp is 11.0.
Using the method mentioned by Stephenson, it is ok!

Thanks
